Absent bad behavior, the force put on the Lark's bicep is under 10 lbs. How
determined? Swing really fast, compare effort to a 10# barbell curl. My
wife is a great swing partner (and game for the experiment, which we tried
from both sides in "traditional ballroom" hold). Slower/normal swing was <5
lbs.

Obviously bad behavior clampers, leaners and hangers would change the
situation.

 I think normal force should be easy. That can be built into a pad on

 Unless we had multiple pads each of which had force sensors in all 3

 Now that I think about 3 axis force sensors, i wonder if there's much

Another possibility would be either a university dance department or the
department that does human performance (sports) and/or physical therapy.
They might have the required gear to analyze dance motions.  But, they will
probably ask, what problem are you trying to solve?  Once you have the

 What I call support is against centrifugal force, not vertical. Of
 course, there's no need to lift the other dancer, and it's a really poor
 idea.

 As Jeff pointed out, in a fast swing, there's a lot of centrifugal
 force, as seen from our rotating frame of reference in the swing.  For
 physics buffs, centrifugal force increases as the square of velocity, so a
 swing that goes around three times in 8 beats rather than twice (1.5x
 faster rotation, the first-level "fast swing") has 2.25 times as much
 outward force to support.  Estimating a 25 cm radius (about 50 cm between
 the centers of mass of the two dancers, in the middles of their abdomens,
 which I measured with a tape measure) and a 70 kg (150 lb) dancer, that's
 an outward force for each of the two bodies of almost 390 Newtons, or
 nearly 90 pounds.  Much of that will be borne by the friction between the
 dancer's feet and the floor, but the rest will be held by the supporting
 dancer(s).  How much depends on how they lean.  For a standard swing (2
 rotations per 8 beats), it's just under 40 lbs.  Fortunately, you only have
 to hold it for four to eight seconds at a time, or actually less as you
 accelerate and decelerate inside that time, though the peak force will then
 be higher.

 ...and now I add...

 Despite starting with it above, myself, I think we're somewhat
 misleading ourselves with this Mv**2/r calculation.

 The key thing here is that a centrifugal-force calculation
 (centripetal, actually) makes some assumptions that we dramatically violate
 when we dance. We are not rigid bodies. At best, we're collections of many
 light rigid bodies (our bones) linked by ligaments, tendons, and muscles,
 and bearing all sorts of other masses that move relative to one another,
 storing momentum until we can deal with it in the next step.  We
 effectively pump momentum up from our feet, into our bodies, and down to
 our feet on each step. We transfer it to the other dancer through our arms
 and theirs, and their

Are you actually thinking of doing this?  Why? Would it help anyone dance
better? If someone does this kind of thing for work and could tap into
those resources, it might be practical.  Otherwise, this looks like the
kind of setup that would require significant thought, effort, and expense.

One approach would be to green-suit up in a video-game studio, and then tap
into the calculations that the game software uses to create game motions
from human ones.  That wouldn't be measurements of forces directly, but it
would be pretty comprehensive.  You'd know where all the momentum went and
it would calculate transmitted forces through every surface, which you
could sum for the hand and arm, etc.  They might also have force sensors of
some sort.  Somebody must have, at some point in the development of those

Funny thing, I wrote the email below last Sunday and thought, do the
world's callers really want a physics calculation on their mailing list?  I
decided the better of it and didn't send it.  Ok, I guess I was wrong...

What I call support is against centrifugal force, not vertical. Of course,
there's no need to lift the other dancer, and it's a really poor idea.

As Jeff pointed out, in a fast swing, there's a lot of centrifugal force,
as seen from our rotating frame of reference in the swing.  For physics
buffs, centrifugal force increases as the square of velocity, so a swing
that goes around three times in 8 beats rather than twice (1.5x faster
rotation, the first-level "fast swing") has 2.25 times as much outward
force to support.  Estimating a 25 cm radius (about 50 cm between the
centers of mass of the two dancers, in the middles of their abdomens, which
I measured with a tape measure) and a 70 kg (150 lb) dancer, that's an
outward force for each of the two bodies of almost 390 Newtons, or nearly
90 pounds.  Much of that will be borne by the friction between the dancer's
feet and the floor, but the rest will be held by the supporting dancer(s).
How much depends on how they lean.  For a standard swing (2 rotations per 8
beats), it's just under 40 lbs.  Fortunately, you only have to hold it for
four to eight seconds at a time, or actually less as you accelerate and
decelerate inside that time, though the peak force will then be higher.

...and now I add...

Despite starting with it above, myself, I think we're somewhat misleading
ourselves with this Mv**2/r calculation.

The key thing here is that a centrifugal-force calculation (centripetal,
actually) makes some assumptions that we dramatically violate when we
dance. We are not rigid bodies. At best, we're collections of many light
rigid bodies (our bones) linked by ligaments, tendons, and muscles, and
bearing all sorts of other masses that move relative to one another,
storing momentum until we can deal with it in the next step.  We
effectively pump momentum up from our feet, into our bodies, and down to
our feet on each step. We transfer it to the other dancer through our arms
and theirs, and their back, if we have a hand there.

With that in mind, consider this model of a swing.  Each dancer's upper
half is trying to execute rigid circular motion.  Our lower bodies (hips
down) are doing something else, and half our mass is down there.  So, drop
my estimated 90 lbs to 45 just for that (I'll drop it more in a minute).
The lower half is essentially stepping a figure with 90 or 135 degree
corners on each beat.  Consider the left foot.  In a standard swing (2x in
8 beats), it is walking a square, directing momentum along the sides of the
square that the upper body picks up and turns into rotation.  Half of each
square side brings that leg closer to the middle, the other half takes it
farther away.  We land, push off, and do it again and again. That push-off
supports the centripetal needs of both legs (through the hip joint) and
some of the upper body.  If there is an outward lean off the right foot,
additional centripetal support is needed from either the legs or arms.  The
right foot is mainly a pivot, while both feet support gravitational weight.

Good dancers constantly adjust how far out their left feet land on each
step and how hard they push off, simultaneously satisfying both their
centripetal needs and the required spin rate.  This lets them control how
much inward force they draw from their feet into the upper-body rotation to
supplement the arms.  That reduces the support needed from the arms well
below 45 lbs.  It can reduce it to zero.  Tweaking the lean also adjusts
where the axis of rotation is, to balance the different masses of the
dancers and make their differing force impulses produce matched torque
impulses.  Dancers use the beat to step in sync with the other dancer's
legs, or these torque impulses would come at different times, and the swing
would wobble and fall apart, as Chris Lacey alluded to.

So, yeah, it's complicated, yet even children solve this problem when they
swing.  Everyone is an intuitive physicist!  And, each time I think about
this kind of thing, I get more amazed at the engineers who make robots.
Has anyone taught a robot to do a contra swing, yet?

I had poked around with the math as well, but struggled with all of the
estimates. I'm happy to see Jeff taking a stab at this and discussing.

I think likely some of that force is taken by core muscles, and transferred
to the feet against floor, and such.

This would be a really cool practical kinesthetics research paper!

Hi Chris,

Thanks!  Note that it's a bit more complicated than where the center of
mass is: you need the moment of inertia.  For example, imagine comparing
(a) a point mass at r=1ft and (b) the same mass divided into two bits at
r=2ft and r=0ft.  The center of mass in case (b) still rotates with r=1ft
but the cases aren't equivalent: you need 2x the force in case (b). [1]

But you may well be right that the effective radius is under 1ft!

Jeff

[1] Doing the math:

F_a = m (ω2πr)^2 / r = m * r * (ω2π)^2
F_b = m/2 (ω2π(2r))^2 / (2r) + 0 = m * r * 2 * (ω2π)^2
F_a = 1/2 * F_b

 don't think swinging with a scale between your hand and partner's back and
 your hand would be comfortable, and it would be hard to read.  Let's try a
 bit of physics.

 If you like to swing quickly you might go 4.5x around in twelve beats,
 which is 45rpm at a tempo of 120bpm. Let's guess the people each weigh
 150lb and approximate them as point masses two feet apart. Doing some math:

 r = 1ft
 m = 300lb
 ω = 45rpm = 0.75 hz

 v = ω2πr
   = 0.75 hz * 2π * 1ft
   = 4.7 ft/s

 F = mv^2/r
   = 300lbm * (4.7 ft/s)^2 / 1ft
   = 300lbm * 23ft / s^2
   = 6662lbm * ft / s^2

 1lbf = 32.17 lbm * ft / s^2
 1lbm = 0.0311 lbf * s^2 / ft

 F = 6662 lbm * ft / s^2
   = 6662 * 0.0311 lbf
   = 207lbf

 This says you need ~216lb of force to hold the dancers together! If
 you're rotating more slowly, perhaps 2.5x in twelve beats, it's still a
 significant 64lb.

There's actually another factor of two if you both have your hand on the
other person's back or shoulder. To get the needed centripetal force, you
both are contributing.

You might say, "you need to lift me and I need to lift you" but that's not
quite right, because my shoulder is lifting your hand and your shoulder is
lifting mine.

To be more explicit let's use your 200lbf example which should actually be
100lbf. My hand can provide 50lbf to your shoulder and my shoulder can
provide 50lbf to your hand. I didn't feel the force my shoulder is
providing to your hand because it's so close to my core.

This is also how we can be uneven in strength and still rotate in place. If
I'm weaker and my hand is only providing 25lbf to your back, my back can
provide 75lbf to your hand, but that feels easy.

I'm going to address other forces that are in pay in a separate message.

Hi Chris,

Thanks for reviewing the calculation!  Imagine that I hold you around your
back with both hands, and you put your hands up in the air and enjoy the
ride.  While I don't think we could get anywhere near 4.5x around in 12
beats if you did that, do you agree that where my hands meet your back I'd
need to provide both enough force for our combined weight?

(I'm not claiming each person needs to provide ~200lb, but that this total
force must be covered by the couple somehow)

I think you're trying to calculate two 150lb dancers, but you've calculated
for a 300lb mass, but you shouldn't do that doubling. I'm exerting enough
force to provide your centripetal force and vice versa. Those forces oppose
one another, but they don't add up. That is a factor of two error.

I have to think more about one foot radius and 45 rpm and read upthread
more.

216 lb?!  That's certainly not in accord with my lived experience over decades 
of contra dancing. Jeff, assuming your physics and math are all correct, how 
much of that force is accomplished by our feet on the floor, rather than upper 
body connection with a partner? 

I haven't been dancing in a while, but I remember many swings, even fast ones, 
feeling almost weighless.

I was curious about John's "The shoulder-blade connection is purely to
counteract centrifugal force.  That is not normally a lot of force, so it
shouldn’t make you tired." above.  While ideally you could measure this, I
don't think swinging with a scale between your hand and partner's back and
your hand would be comfortable, and it would be hard to read.  Let's try a
bit of physics.

If you like to swing quickly you might go 4.5x around in twelve beats,
which is 45rpm at a tempo of 120bpm. Let's guess the people each weigh
150lb and approximate them as point masses two feet apart. Doing some math:

r = 1ft
m = 300lb
ω = 45rpm = 0.75 hz

v = ω2πr
  = 0.75 hz * 2π * 1ft
  = 4.7 ft/s

F = mv^2/r
  = 300lbm * (4.7 ft/s)^2 / 1ft
  = 300lbm * 23ft / s^2
  = 6662lbm * ft / s^2

1lbf = 32.17 lbm * ft / s^2
1lbm = 0.0311 lbf * s^2 / ft

F = 6662 lbm * ft / s^2
  = 6662 * 0.0311 lbf
  = 207lbf

This says you need ~216lb of force to hold the dancers together! If you're
rotating more slowly, perhaps 2.5x in twelve beats, it's still a
significant 64lb.

Jeff

Here's a 1989 recording the Portland OR dance did in a recording studio:
https://www.youtube.com/watch?v=4o_qLQUH-7k .  I see almost all "outer arms
making a point, gent's right hand behind lady's back, lady's left hand
behind gent's shoulder" hold (hereafter 'ballroom' though as illustrated
above that's a fraught term).  At 0:58 and then again at 1:28, 1:58, 3:02
etc there's a couple with a symmetrical hold where they each have their
right hand around the other's waist, with their left hands joined low in
the center.  I didn't watch the whole video, so it's possible there were
other couples that did other holds at some point?

Here's 1987 in Mendocino: https://www.youtube.com/watch?v=pTOKMwrl-7Q .  I
only see ballroom holds.

Here's 1986 in Cambridge MA: https://www.youtube.com/watch?v=n2-pBs9BY3Q .
Outdoor demo performance.  Almost all ballroom holds, but at 4:04 the
couple all the way on the right has outer hands in a forearm hold (which
they continue doing in later iterations of the dance).

Here's 1986 in Francestown NH: https://www.youtube.com/watch?v=O09f-3yGMuE
At 0:30 I see two ballroom holds and two where the outer arms are holding a
bit above the elbows.  At 1:06 I see two ballroom holds, one of the hold
from 0:30, and one of the symmetrical holds I described in the Portland OR
video, though note that this is many of the same couples.  Jumping ahead to
8:38 I see three ballroom holds and where the outer hands hold each other's
forearms. Separately, I really like how enthusiastic the balances are: you
can feel the room shake through to the camera!

Here's one labeled 1986 Chico Contra:
https://www.youtube.com/watch?v=UCYAyEj6jWg  Almost all ballroom holds,
except for one couple where the lady's left hand is on the back of the
gent's right arm instead of behind his shoulder (doesn't look comfortable
to me!)

Here's 1976 in Bloomington: https://www.youtube.com/watch?v=_n2A3955G2w .
Looks like a performance.  At 0:10 I see three couples where the outer
hands are joined as in ballroom, the gent's right hand is around the lady's
waist, and the lady's left hand is again on the back of the gent's right
arm.  Then there's one couple doing the symmetrical swing with left hands
joined low between their bodies. Same again at 0:44, 1:11, etc.

Here's 1967 somewhere in New England:
https://www.youtube.com/watch?v=q6E1AtqyvFM .  I see ballroom at 0:35,
0:37, 3:15, 3:16, 5:08, 5:10.  Then at 1:05 (and then again in the
background at 5:11, and then again at 5:23 and 5:33) I see a forearm hold
with arms that are straighter than I'm used to.  At 2:08 I see a hold where
the gents hands are both around the lady's waist and the lady's hands are
both over the tops of the gent's shoulders.

Here's 1981 in Belmont MA, but it's an hour and I'm going to bed:

2024-03-26 Thread Stein, Robert via Contra Callers
Thanks for this practical and historical approach.  I recall Ted Sanella 
advocating a barrel hold swing.  I like that because both swingers share 
equally in the tension to counter the centripetal force. To reemphasize, the 
hands are not around the back but on the shoulder blades (or sides of the back 
if very different in height).  It is true this brings the dancers closer 
together, but also prevents touching in front.  Personally I prefer one or 
another barrel hold swing because of the extra security and equal strain on the 
two shoulders.  When dancers insist on a ballroom swing I have to swing slower 
to avoid the right arm strain. (This has nothing to do with supporting your own 
weight which is of course necessary.)  Barrel hold is also the customary 
position for Scandinavian turning couple dances where there is a lot of 
centrical force.  I have never found differences in height to be a problem. It 
just needs a slight adjustment of where the hands are higher or lower on the 
other person.  I swing with some people a foot taller than me and others a foot 
shorter.  If a person is very sensitive about their personal space then perhaps 
a crossed arm hand grip is the way to go to swing fast.  However, that is less 
secure because of the possibility of a hand losing its grip.

Looking through old media to figure out what swing positions were common
sounds like fun!  I think video might be more promising?  Here's a few
annotations of a video, where the numbers are timestamps and each bullet
describes the couple that's in the middle of the frame at the timestamp.  I
only counted each couple once:

Cambridge MA, 1990: https://youtu.be/dC0qQYWjdh0?si=JWkNH0g93yo6VWrC
* 3:41: lady's hands behind gent's arms, gent's right hand behind lady's
back, gent's left hand behind lady's arm
* 4:12: outer arms making a point, gent's right hand behind lady's back,
lady's left hand behind gent's shoulder
* 4:14: outer arms making a point, lady's left hand on gent's shoulder,
gent's right hand on lady's back
* 4:44: outer arms making a point held way out, lady's left hand behind
gent's shoulder, gent's right hand on lady's back
* 5:16: outer arms overlapping, inner hands on backs with lady above gent
* 5:17: outer arms making a point held low, gent's inner hand on lady's
back, lady's inner hand behind gent's shoulder
* 5:18: outer arms making a point and held out, gent's inner hand on lady's
back, lady's inner hand behind gent's arm
* 5:48: both lady's hands behind gent's shoulders, gent's left hand behind
lady's elbow, gent's right hand behind lady's back
* 5:49: outer arms making a point, gent's right hand behind lady's back,
lady's left hand behind gent's shoulder
* 5:50: outer arms making a point, gent's right hand behind lady's back,
lady's left hand behind gent's shoulder

The "outer arms making a point, gent's right hand behind lady's back,
lady's left hand behind gent's shoulder" hold, which I think of as the
standard today, was about half of them, but there was quite a lot of
variation.

I tried to do this with a Fitzwilliam 1975
 clip, but there were too many
cuts.  The 1964 video  would
be another one to try?

Responding to various points.
And, obligatory acknowledgement that there's always regional differences
(and, perhaps ultimately that is what this thread is really about?)
I beg you forgive me for directness, and please assume a friendly tone and
desire for friendly discussion, as that's what's intended.

I just thumbed through two big choreo milestone books marking approximately
the beginning of the less-1s&2s age of contra - Balance and Swing, and
Zesty Contras - and absolutely Ted Sanella and Larry Jennings.
The short version: despite being contemporaries and the books published a
year apart (1982 and 1983), they describe slightly different swing holds,
where:
- a gent's right hand is either on the waist on the small of the back
(Sanella) or a little higher (Jennings, via the illustration on the cover
which he points out in the description is what to follow)
- a gent's left hand is either a typical ballroom palm-up supporting the
lady's right hand (Sanella) or behind the lady's right upper arm (Jennings,
with Sanella noting the variation as well) - with a lady's hands
- a lady's left hand is resting on the top of the upper arm (Jennings) or
"behind the upper arm" (Sanella)

So even in 1982/1983, there was no agreed traditional swing position, and
holds described by both did include women holding men in ways that were
supporting from behind rather than everyone agreeing that their hand is
"resting on top" as with other couples' dances.
Obviously dance evolves over time, and I'll circle back around to that
after I touch on some specific points:

RE: Joe: "They lean back or sideways or press back against the Leftie’s
supporting right hand."
Agree, these are bad habits. The "leaning back" may be describing "the
feeling of centripetal force", but also I have definitely experienced
people who lean back.

RE: Neal: "both-palms-flat swing  ...  forces the swing together because
you are limited to the length of the shorter arm."
I don't think this is accurate.
This was covered elsewhere in the thread. The shoulderblade isn't small,
and adjustments can be made to adjust for height or size differences.
There's always exceptions, sure.
Certainly, when I swing young kids, we're not doing shoulderblades. Then
again, they have a lot less mass than an adult, so there's less support
that's needed to be given.

RE: Neal: " putting your palm in the middle of my back means you’re going
to be on top of me."
I agree, however, a good flat-palms swing hold is not in the "middle" of
the back. There's a gap between shoulderblades, so a hand in the middle is
partially off the shoulderblade.
I like how Lisa Greenleaf describes it as the curve of the hand often can
naturally curve around the shoulderblade.

RE: Neal: " if partners are the same height/arm length then the arms are
coming in at the same point and going to the same point, resulting in
collision. SOMEONE has to adjust up or down AND forward."
I mean, I suppose, technically speaking? But I think everyone on this list
here has been dancing for years, and "elbow collisions" isn't a thing I've
really experienced or heard discussed.
So, I conclude that this may in theory be possible, but people just ... do
it?
As a lark/lefthand role, my right arm comes into a swing from a bit of an
under-scooping motion. As a robin/righthand role, my left arm comes in more
open and I wait half a moment to let the lark engage their right arm before
I try and wrap my right arm around.
It's similar-ish to the anticipation leading into a good connection on a
star promenade.

Further to this point, if I were using the traditional "woman left arm
rests on top", I'd have to wait until the lark's arm has engaged, anyway.
Which means that traditionally, women have done that extra bit of work in
the dance of that waiting, reading the other dancer's movement, and timing
their own move --- and I wonder how much of that had gone unnoticed.

This all said, the explanation that you give, Neal, may not work as
wellwhen it's not taller men dancing with shorter women.
Some women are tall and dance the Robin/Righthand role.
Some men are tall and dance the Robin/Righthand role.
Some women are shorter and dance the Lark/Lefthand role.
Some men are shorter and dance the Lark/Lefthand role.
Some men dance with men, some women with women.
Etc.

So dancing requires a need to adjust our arms to "make a swing work for
both people" as a universal and generic skill.
Thankfully, I think it's one that's actually more automatic than it may
seem!

Regardless of how we discuss the technical and kinesthetic aspects of
contra, I teach (and I think most callers teach) that dancers need to
adjust themselves to every partner and neighbor, and find a happy medium
that works for both people.
If someone doesn't want to put their hand flat on my shoulderblade, that's
fine and I'll adjust by limiting my upper-end swing speed.
I think we all share the value that a skilled contra dancer can adjust
their style to meet another dancer's di

Hi Julian,
Regarding both dancers trying to put their palm flat on the other persons
back, I agree with Joe.

The both-palms-flat swing does multiple things.

First, it forces the swing together because you are limited to the length
of the shorter arm. I’m six feet tall with broad shoulders and long
arms—putting your palm in the middle of my back means you’re going to be on
top of me. I don’t care who I’m dancing with—I want space, and I’m not OK
with that.  With a standard hold, I can give partners lots of space.   (Also,
I sweat from the head a lot. You want that space, and no one wants their
hand on my back.)

Second, if partners are the same height/arm length then the arms are coming
in at the same point and going to the same point, resulting in collision.
SOMEONE has to adjust up or down AND forward. This means a changed angle
for one person, and due to the change in angle a shortening of the hold to
match the arm that adjusted (usually on top), thereby pulling the swing
closer together than otherwise necessary…which also puts the other person’s
arm (typically lark, and also typically longer) in a non-natural position,
which is likely to be physically uncomfortable and potentially harmful.

Hi Jeff,

  No, I mean horizontal force.  People don’t keep their own balance 
or their own weight, especially if they have been told to “give weight”!  They 
lean back or sideways or press back against the Leftie’s supporting right hand. 
That is what is tiring.  That pressure is often much greater than the 
centrifugal force.

 

Happy dancing,

Hi John,

 

I think people may be using two different things by "support" here?  Julian and 
I, along with a few others in this conversation, are using "support" to mean a 
horizontal force, providing a counterbalancing force to resist the centrifugal 
force that would otherwise send the two people off in opposite directions.  I 
think you're interpreting "support" to mean a vertical force, which I agree you 
shouldn't need to provide.

 

If you're swinging quickly there really is quite a lot of centrifugal force.  
Sometime I'd like to try getting some sort of scale involved to figure out how 
much!

Hi Joe,

You mean, palms flat on the back of shoulderblades? If so, it's how I teach
it, lots of callers teach it, and this is the first I've heard a complaint
about it.

That said, you describe: "I've had my elbow bent backward by eager robins
pressing my elbow in to get their elbow in the right place."

That _sounds like_ what I call "arm clamping". While yes, putting Robin's
hand on the outside of the shoulder also alleviates the clamping, it's not
the only way to fix it. A Robin can lift their elbow. (I just workshopped
the issue with my partner in the living room to test a variety of height
and holds out to confirm what you were saying, as well.)

The other issue is that if both dancers don't have hands flat on the backs
of each other, it's more difficult to maintain an open frame when swinging.
One usually winds up _closer_ when hands are resting on shoulders, unless
one dancer is significantly stronger and the other is fairly petite.

I know that my right arm will get seriously fatigued and sore if I have an
evening too many times as Lark with Robins providing insufficient support.
And I've heard plenty of dancers say similar.

That said, all bodies are different. If yours works where the swing hold
works better for you the way you describe, that is what it is, yeah? But I
might recommend considering workshopping swings further, because what
you're requesting is counter to prevailing teaching. If I understand
correctly (and it's always possible I'm missing something.)

In dance,

Not the standard ballroom, with the robin's arm on top of the lark's, but
an alternative that I've seen occasionally, but for a number of years now,
where the robin tries to put their left hand in the same location on the
lark's back as the lark has their right hand on the robin's back.  I know
at least one prominent caller who teaches this hold in their newbie
workshop and tells their dancers that both sides need to do this to provide
equal support in the swing.

While I like the principle, the practice can hurt. If the dancers are not
grossly mismatched in size/arm length, it won't be possible to do this
without their elbows occupying the same space.  I've had my elbow bent
backward by eager robins pressing my elbow in to get their elbow in the
right place.  Even if it doesn't go all the way to pain, it pretty much
eliminates my ability to provide any support, unless I "fight back" by
pushing my elbow out and resisting the inward pressure, essentially
refusing the position.  I'm also focusing entirely on protecting my elbow,
so it kills any enjoyment in that swing.

Please gently discourage this hold.  If a robin wants to give major support
in a swing, the symmetric swing holds, the barrel, the one Jeff described,
or even a mirror of the ballroom where the lark's arm is on top are much
better opportunities.  A robin whose arm is longer than their lark's arm
can also reach over or around the shoulder in a ballroom hold (robin's arm
on top) to add support.  Just don't push down on the shoulder.

Personally for me, the standard ballroom swing helps me to "flip the
switch" in the brain on which side of the swing I'm "supposed to" end on
(assuming we're not switching roles back and forth for fun lol). If my left
arm is the "pointy arm," I'm ending on the left; if my right arm is the
"pointy arm," I'm ending on the right. I don't have to consciously tell
myself "I'm the Lark" or "I'm the Robin," my muscle memory just takes over
and I just end on whichever side my arm position tells me to 😅.

I enjoy neutral swings, but if we're not planning on switching roles
without warning through an individual dance, I tend to stick with the
traditional ballroom figure.

"At the time, it almost never happened that the one in the lady's role
actually swung like a lady.  I'm not sure when that became the norm."

When I started dancing both roles, around 2005, I remember initially doing
it as you said, with gender-neutral swings with the gents I encountered.  I
remember being surprised sometime around 2006-2007 when I ran into a few
guys dancing switch who indicated they wanted to do the standard ballroom
hold.  By 2008-2009 I think my male friends and I were dancing the lady's
role in the standard way?

I love the barrel hold, but some of my partners have reacted in a way that
indicated it was too intimate for them.  This is especially true if I have
to lean over to do it, as that puts my face pretty close to theirs (I'm
pretty tall).  It's also difficult to do without frontal contact if one or
both partners is well on the heavy side.  But, all that aside, if you and
your partner like fast swings, it's a great hold, more stable than
ballroom, with four arms providing support rather than one.

In the late 1980s and early 1990s, when guys danced the lady's role (using
the terminology of the time for reasons you'll see in a moment), we'd
almost universally be offered the "gender-neutral swing", which is
symmetrical and very stable for fast swinging: both right arms are around
the other's back and both left arms go over/around the other's right arm,
bend 90 degrees at the elbow, pass between you, and clasp left hands around
each other's forearms between your bodies.  At the time, it almost never
happened that the one in the lady's role actually swung like a lady.  I'm
not sure when that became the norm.  I would occasionally do it with a
particular guy partner whom I liked to dance with.  We practiced it first
and then did it with each other, but we gender-neutral-swung our
neighbors.  We got some pretty surprised looks from our neighbors when we
swung each other. At least one guy asked me if that partner and I were an
item.  Times and role terms and what people read into dance behavior
change...

In general, I'm quite happy to swing with guys in either role when they're
happy to swing with me.  But, it's awkward and uncomfortable in the extreme
to be going up an entire line of consecutive frowns, growls, and looks of
disgust as a guy dancing the robbin...enough that I haven't returned to the
dance weekend where that happened in Fall 2022, even though it was pretty
great in other ways.

The one swing style I really dislike is a modified ballroom position where
the robbin tries to put their hand on the lark's back in the same place
where the lark's hand is on theirs.  I know some people actually teach it
this way, I guess as some kind of equality thing.  It's terrible, because
their elbow and the lark's elbow then have to occupy the same space, which,
well, physics.  If I'm the lark and their arm is outside mine, when they
try to provide support, it hyperextends my right elbow, eliminating any
chance I can provide support and sometimes inducing pain before I can
either force my elbow back out, displacing their hand from my back, or pull
my arm up to rest it on their arm in a mirror of the traditional ballroom
hold.  I hope we can convince everyone to stop teaching this hold, as it
usually doesn't work as intended and it can hurt the lark.

One assist that does work in ballroom position and requires no
communication is, if the robbin's arm is as long as or longer than the
lark's, they rest their left arm on the lark's right, extending the entire
length of the arm and then reaching around/over the lark's shoulder to
provide some support on the shoulder blade.  In my case, at least, if they
are short enough that they can't do this, then they're often also light
enough that additional support isn't critical, though it does make for more
connection.  It's important not to press down on the shoulder, though. Only
pull forward.

At the last couple of dances in the last few days, I thought about this
email thread and observations.

Short and simple:
A "barrel hold" swing:
- Seemed to provide a little bit more space than a ballroom hold
- One neighbor offered it (by chance) really clearly, as a lark, with his
left arm curved into a sort of "offer a hug" type position. As we engaged
in the swing hold, he placed his left arm in place, and it guided things
in. It worked pretty well for me, at least as an experienced dancer.

I can’t answer whether the robin's would always HAVE to go above the lark’s in 
the modified ballroom swing, but I would intuitively think that having that 
rule/understanding might make it easier for dancers to make the transition from 
ballroom to modified ballroom because the robin’s arm is always on top in 
standard ballroom swing. Also, the lark’s hand is typically cupped upwards with 
the robin’s hand above the lark’s in things like a balance or even a handhold 
in a circle move, so having the hand/arm orientations the same in the swing 
would also seem more intuitive to me if I were just learning this swing.

I personally plan to start teaching this modification as an option for a
swing in my beginner's lesson. I'm just curious as to whether there's a way
one can quickly signal that you'd like to do this modified swing instead of
the traditional ballroom... Like, if you want to ricochet through a Hey for
Four, you put your hands up in front of you; if you want to twirl/be
twirled, you raise your joined hands (and the other person can decide
whether to oblige or not). Is there a quick signal that allows one to
quickly get into this modified swing without needing a verbal discussion
about it?

[Callers] Re: Modified ballroom swing position: seeking more conversation and info

2024-03-15 Thread JJ via Contra Callers
I think the neutral swing is pretty cool, and I want to give it a go myself
just for fun, but I have an aside:

On the one hand, nobody should be forced to touch someone they don't want
to touch, that's basic consent. And people have every right to refuse to
dance with someone they're uncomfortable with, and this style of swing is
one good method to make people more comfortable...
However, my spidey-senses tend to go off whenever I encounter a man who
doesn't want to swing with another man... My question to those men is:
what's going through your head when you swing with a woman? Is dancing so
sexualized for you that you think everyone is thinking sexual/romantic
thoughts about everyone they're swinging with? It just makes me concerned
for just about every woman a man has danced with when he reacts so
viscerally to a 10-second swing with another man. Nobody's asking you to
marry them, nobody's inviting you into their bed, we're literally just
there to dance and make friends. It gives me the ick.

Larry Jennings ("Zesty Contras", "Give and Take") called what we've been 
calling the ballroom hold because it's a modification of the position for 
ballroom dances like waltz and polka, that modification being that the inside

intentionally step between your partner's feet; when you're in the 
ballroom-dance hold, of course to rotate you alternate stepping forward and

and if you try to do that in a contra swing the results are somewhere between

Anyway, as a result, the arm that goes to the partner's shoulderblade is 
necessarily stretched to some degree across the front of your partner's body - 
more stretched if your and your partner's feet are further apart, less 
stretched if they're closer together - and it's much easier for that arm to

Katherine --

I think that the way you were doing the ballroom swing before you modified it 
is not how most of the rest of us do it, and that this in itself produces some 
of the problems your modification solves.

I'm sure under the impression that the 'standard' ballroom swing [*] has the 
robin's arm on top

Here's a video (from the East Coast) whcih sure looks to me (from the West 
Coast) like how we do it out here.

https://youtu.be/lQ0R5iHT-l8?si=OYKTgBXg0dLyKQza

(Of course there has to be some adjustment for height difference, and you don't 
want a tall person having to bend way forward and then support a short person 
or a short person getting their shoulders stretched by reaching way up; your 
modification (robin's hand goes on upper arm rather than shoulder blade) is 
sometimes the best solution for height differences even when the default hold 
is 'standard' as shown in the video.

Please try the 'standard' hold with your husband and see if it's any better for 
you that what you were using..  And then we can at least all be talking about 
the same thing.

I say "some of the problems" because I think the appropriate solution for 
creepy dancers lies in counseling or ejecting them rather than in changing the 
hold, because creepy guys gonna creep regardless of the hold.  It's really only 
a solution for people who are dancing too close for comfort and don't realize 
it, and I think the solution for that is for people they are making 
uncomfortable to either tell them or tell management and have management tell 
them.

I  don't see why in either hold anybody should be grabbing you by the waist.  I 
also think that there's going to be some irreducible minimum of innocent / 
unintended boob and butt grazes, especially among unsure dancers - the chances 
of a new dancer in a courtesy turn having their behind-the-back hand in an 
unexpected place and the other person, trying to take that hand (which they 
can't even see, by the way)  is going to end up putting their hand on hip, 
waist, or butt.;  Do you want to change the courtesy turn hold to avoid that?  
Because you don't have to interoperate with other dances, you could change the 
courtesy turn hold into a hands-in-front promenade hold and avoid that risk)

On a pedantic note, I've been having trouble understanding the hold before you 
posted the picture, because "modified ballroom swing" is, as I recall, what 
Larry Jennings ("Zesty Contras", "Give and Take") called what we've been 
calling the ballroom hold because it's a modification of the position for 
ballroom dances like waltz and polka, that modification being that the inside 
of the feet being square-on to partner, or slightly offset so that you 
intentionally step between your partner's feet; when you're in the 
ballroom-dance hold, of course to rotate you alternate stepping forward and 
stepping backward.  Modified to fully offset, you both step forward the whole 
time.

(One of the reasons an ex of mine hated contra dancing was that she'd fully 
internalized the step-between-the-feet thing in foxtrot, one step, waltz, etc, 
and if you try to do that in a contra swing the results are somewhere between 
unsatisfactory and actively dangerous.)

Anyway, as a result, the arm that goes to the partner's shoulderblade is 
necessarily stretched to some degree across the front of your partner's body - 
more stretched if your and your partner's feet are further apart, less 
stretched if they're closer together - and it's much easier for that arm to 
contact the front of the partner's body somewhere in the boob area than it is n 
a square-on ballroom hold.

As far as I can tell -having only fairly-small man boobs -  you can manage to 
reduce the impact by adjusting the angle at which partners are facing and how 
close your the right side of your right foot is to the right side of theirs.  
All the stuff that you'd naturally want to do to avoid unintended forearm-boob 
interaction is, counterintuitively, unhelpful so long as you're keeping the 
shoulder contact  - you want to keep your distance so you keep your feet 
further away, and that changes the angle, reducing the clearance between arm 
and boob.  Or you want to pull the shoulder near the grazed boob back -recoil 
from the touch, or whatever - and that also makes it worse because it changes 
the angle and brings more boob surface into contact with the arm.  
Counterintuitively, adjusting things so that the pointy-end side is farther 
apart helps by increasing clearance on the blunt-end side where the boob 
contact is happening because it brings you closer to square-on, reducing the 
arm-boob a
 ttack surface.

Sorry everyone - I am clearly not the global authority on this hold,

something unexpected-


In the case of me and my partner dancing, it was actually better for 
both of us if his arm went below mine even though he is taller-  I guess 
because he is taller, his upper arm is also longer, so somehow it still 
made sense for my arm to go on top. (If anyone thinks they can better

2024-03-13 Thread Julian Blechner via Contra Callers
I would love to read elaboration / articulation on why a ballroom hold
feels more "intimate" than other holds?

Is it a matter of the historical social attachment we have in our minds
with couples dances that use the hold, and romance in our culture?

Is it a physical proximity? (I find ceilidh holds to be closer, crossed
arms has my hands bearish their belly which has its own intimacy to me,
though sometimes barrel holds can be done with a bit more space - though I
wouldn't say the default)

Is it something else?

Maybe if we looked at the why, it'd give insight to what a solution to an
alternate swing hold and/or an adjusted mindset might entail?

Hello!
I was the one who suggested the modified ballroom swing, and I'm going 
to respond here to both some of Becky and Jerome's and John's questions/ 
thoughts.


Women's discomfort in conventional ballroom hold
I did actually mention in my initial email that as a cisgender woman, I 
have really appreciated the additional space that the modified ballroom 
hold creates between me and the men I dance with.
Actually as a not particularly touchy-feely human being, I appreciate 
the additional space it creates between me and anyone I dance with!

But I have especially appreciated the space between me and any male partner.

Interestingly, I didn't think about it too much in the past.  I was 
fairly comfortable swinging with anyone, and our group has a good vibe 
so there isn't much creepiness.  I felt fine with the conventional 
ballroom swing.
But -- now that we have implemented the modified ballroom hold as the 
standard with all neighbours and also as the standard with a partner if 
you don't discuss otherwise, it's been *very* interesting
I've sometimes swung with a male partner who decides to use conventional 
ballroom without discussing it --and  I suddenly feel VERY 
claustrophobic about it!
I will usually say to them when I get a chance - "let's remember to use 
the elbow-hold now!" - and as soon as they do, I  instantly breath a 
sigh of relief.  It just feels way more comfortable to me.  Without 
exception.


-- (and to give these fellows who launch right into conventional 
ballroom hold the benefit of the doubt- they tend to be our longest-term 
dancers and it I think in a lot of cases they just have a hard time 
re-programming - we have only been doing the modified ballroom for about 
6 months, and not everyone comes to every dance. I'm giving them time to 
get used to the new normal.   That said, I am pretty sure there are few 
men who think, "oh, she is a caller, she is an experienced dancer, she 
will be happy to swing closely with me!" .  I have this idea because a 
few of them seem to roll their eyes a bit when I remind them that I 
prefer to dance with the new modified hold :D  Incidentally this has 
never happened with a female partner)...


Inadvertent "boob touching"
This is not something I have ever heard of before in the swing, but 
someone did bring it up a few dances ago when we tried to use a 
modified, more role-symmetrical hold for the courtesy turn, with both 
hands crossed in front.  One of our longtime and larger-busted female 
dancers told me that this was *not* going to work, due to all the 
inadvertent boob touching that happened to her when her partners were 
getting into position.  So we canned that idea! :)  And it made me more 
aware of this issue as something to watch out for.

Thanks for drawing attention to it as a potential aspect of the swing.


Robins arm-clamping and robins feeling like they have to skitter backwards
I haven't consciously encountered either of these issues but look 
forward to hearing more.


(Jerome's point) -Signalling which flavour of swing to use?
So in our community, we have just made it clear that this modified 
ballroom hold is now the new standard.
So, that means for every neighbour you meet, this is how you swing with 
them.
And with your partner, this is what is expected --unless the two of you 
have a consensual conversation and decide on something else.


(and sometimes for fun we do show partway through the dance, some other 
swing holds that partners may like to experiment with, if they are 
comfortablewith each other. John S's page has been very helpful in this 
regard!! Thank you John :) )


Of course, if two neighbours meet each other in the line and they know 
each other well (e.g. maybe they are spouses!), they may spontaneously 
do something else becauuse they know each other well enough to feel that 
out on the spot.  But we make it  very clear that you should not assume 
that your neighbour or partner wants to do something other than the 
standard hold, unless you have an explicit discussion.  Since that's not 
really feasible with neighbours, it means that neighbours in almost all 
cases are going to swing with the modified ballroom and that is that :)


Regarding John's request to get a visual of this hold
- i'll be curious if anyone else on this list is using this new hold, or 
if it is just us in Halifax.


I can't even remember now how we came up with the idea.  It may have 
been through our own experimenting.  A bunch of us have been chatting 
after some dances about how we can make our figures as 
gender-neutral/symmetrical as possible, and we have been trying out all 
sorts of different swing holds to see what might work best for us. 
Sometimes we start with one of John's examples and then see how it might 
be modified if it feels too close.    As I suggested above, we've also 
been trying to figure out more symmetrical-hold courtesy-turn 
alternatives (for robins and larks chains) but so far haven't found a

Hi all,

  The Swing Workshop videos are all available at 
http://contrafusion.co.uk/SwingWorkshop.html - 20 variations!  Plus lots of 
hints and tips on good technique, and how to signal or initiate a certain type 
of Swing.  At the bottom of that page you will find links to more articles 
about Swings.

 

  I would never recommend that the person who’s arm is on top 
(Raven/Lady) tries to reach the shoulder blade.  The lower arm can easily reach 
the shoulder blade, the upper arm can’t.  It is just basic physics.  Lots more 
on that subject at http://contrafusion.co.uk/LadysLeftHand.html

 

  If both people relax and the left-hand person connects with their 
hand on the right-hand person’s shoulder blade then that is enough connection 
for a good Swing.  I always emphasise that you PLACE your hand on the shoulder 
blade, you don’t put pressure on it, or pull it towards you.  Centrifugal force 
will do that anyway if you build up enough speed.

 

  The failure to relax and putting pressure on any other part of 
your partner (hang, squeeze, clamp, grip) are what cause most problems.  I 
start every Swing Workshop for experienced dancers with asking them to relax 
and then telling their partner about anything that is causing pressure or 
discomfort.  Many experienced dancers need this!

 

  I hope some of that helps.

 

  Please could someone post a picture or video of the modified 
ballroom hold that is being discussed?  Or send it to me and I will add it to 
my Web site with a link so that people can see it.

 

  Thanks. 

 

Happy dancing,

   John

Subject: [Callers] Modified ballroom swing position: seeking more conversation 
and info

 

In the discussion about some men being uncomfortable doing ballroom dance hold 
swing with other men, the modified ballroom hold (hand above elbow of partner 
instead of on robin’s shoulder) was mentioned. 

 

In this discussion, much has been said about men who don’t want to do ballroom 
hold with other men, but what nobody has mentioned yet is the scads of women 
(both straight and queer) who have long been uncomfortable dancing ballroom 
swing with men (or often just with particular men). I am intrigued by this 
modified ballroom swing idea because it might solve many problems at once. 

 

I have two simultaneous (and conflicting) emotional responses to men 
uncomfortable swinging with other men:

The ungenerous one is: "As a lesbian I had to get over my discomfort swinging 
with you in order to participate in the joy of contra. If I can do it, you can 
do it." But more importantly (and more generously): We’d like everyone to be as 
comfortable at contra dances as is reasonably feasible. To that end, I am very 
interested in this idea of the modified ballroom hold. It might solve MANY 
different problems. Here are a few that come to mind:

 

1. The enforced intimacy problem: this is not just a problem with straight men 
being uncomfortable swinging with other men. There is a lot of forced intimacy 
in the ballroom hold. Maybe that intimacy is not the best thing to force on 
anyone?. Modified ballroom swing would help with the problem of not wanting 
enforced closeness/intimacy with others for all kinds of reasons: keeping 
distance from the lecherous dancer who uses the ballroom hold as an excuse for 
unwanted intimacy; but also simply to provide a bit of space for folks who 
simply aren’t comfortable being that close to ANYBODY. I recently struck up a 
conversation with a new dancer who was leaving early (because we need to know 
why we’re losing potential dancers) and she said “It just feels too intimate.” 
She didn’t say too intimate swinging with men or with women. Just “too 
intimate” and I got the definite feeling that it was the enforced close hold 
(with everyone) that was difficult for her. I wonder if we would have lost her 
if we used the modified ballroom swing (hand above elbow instead of on 
shoulder). 

 

2. There are other difficulties with the ballroom hold: sometimes there is 
simply not enough room: short arms or large girth can make it difficult to 
reach the back of the shoulder of the other partner at times, and this leaves 
the Lark in the uncomfortable/dangerous position of “where do I put my hand 
now?” While trying to avoid the “accidental side boob graze” issue. 

 

3. Speaking of which, is nobody else out there having trouble with this “side 
boob graze” problem with the ballroom hold? I’m a lesbian who dances the Lark 
role because of knee and hip issues. At least once/even

2024-03-13 Thread Jerome Grisanti via Contra Callers
One challenge is implementation: if the whole group learned the same swing
position, symmetrical or asymmetrical, from scratch, your proposal would
not be a problem unless/until your dancers visited other dances — and even
then. perhaps not a big issue.

In a community with mixed crowds (both experienced and newcomers), dancers
would need to signal which flavor of swing they wanted. And what about
folks with two different preferences meeting for a neighbor swing?

So developing those signals, and defaults, would be my focus. As for the
swing itself, I believe John Sweeny or one of the other UK members of the
list has a video catalog of various swings on a website. Good teaching tips
too.

 Hi, Becky,
This is one that without a good visual to know exactly what this means, I'm not 
sure I like this.  The reason why people are taught to put a hand on the 
shoulder blade is that the shoulder blade is a good solid part of the body to 
put a flat hand and provide the weight to go around in a satisfying swing.  I 
can't imagine this "hand above elbow" thing.  I *have* seen the hand below 
elbow thing, though, but I feel that putting weight on the elbow is more likely 
to cause injury than on the shoulder blade, especially if you are pushing 
upwards on a bent elbow.  I'm guessing that what you are describing is 
something different than I am imagining.  
As for the boob problem, that is something that I feel can be solved by good 
swing technique.  My main issue is when you swing, the hips should be side to 
side, but the torso is should still be somewhat square so that my arm doesn't 
go across the breast.  And as a man I make great effort not to brush against 
anyone's breast by going around as best as I can, by going all the way around 
to the back of the shoulder.  And those times when I do brush against the 
breast, I apologize profusely, and most people are understanding, as the 
apology shows that I'm not there to grope.  

I *think* a lot of people can tell the difference between a grope and accident, 
but I'm probably wrong about this.  I'd like to hear some more thoughts from 
other people on this.  It would be good to know what to do to help prevent 
accidental boob touching.
