Or Beethoven, Schubert, Brahms, Tchaikovsky Wagner, Mahler, Strauss,
Bartok, Schoenberg, Berg, Stravinsky, Prokofiev, Ravel, Debussy, etc.,
not to mention the more "temporally advanced" folks you mentioned.
Plenty of jazz, and decent metal splits beats into fives, and you
can't play in a drum corps without perfect subdivision chops...
sometimes quintuplets are called "20th notes."

But if you want pieces that make heavy use of quintuplets, you would
want to check out Carter (start with the string quartets, for
instance).  Tuplets are often used to allow several people to play
music in different tempi while each attending to a "master pulse."  I
just played a recorder motet where the the low voice was in 3/2, the
middle voice in 2/2, and the upper voice in the equivalent of 5/10
time.  Or, in Carter, often the old quintuplet becomes the new 16th
note and the music proceeds at a faster tempo.

There are plenty of composers who do the same simply using time
signatures.  I've conducted pieces which go fluidly from one meter to
the next -- 3/4 5/6 2/4 3/8 31/32 5/4 19/10 etc.  It's not that hard
once you get the hang of it, but it is hard to get the hang of.

I believe that most competent musicians should be able to handle
rhythmic notation at least up to subdivisions of 6.  Not that they can
usually; but I believe it should be the case -- one can practice
rhythm anywhere.

In addition you can check out Stockhausen, Babbitt, Boulez, Wuorinen,
or most anyone who structures rhythm parametrically.  (pun)  Or, for
an extremely rich but different orientation, check out Carnatic (South
Indian) classical music -- look up "Korvai" for instance.

'the arabian dance' from the nut cracker ballet by tchaikovsky happens to have 
quintuplets. you can hear the piece here:

http://www.youtube.com/watch?v=rx8cCLumV10

listen to the lead melody. sometimes it plays some kind of a slow trill 
(quickly changing between two close notes), which happen to be quintuplets. i 
admit, that they sound like a duplet followed by a triplet, but i have the 
scores of the piece and they are written as quintuplets on 32nd's.

This reminds me, I was just reading The Negative Dialectics of Poodle Play
by Ben Watson, and he quotes an interview with Frank Zappa about his
favorite records:

"'Can I Come Over Tonight' – The Velours. Any musicologist that can find
that record and listen to the bass singer ... he's singing quintuplets and
septulets. And considering where it came from and when it was made (it was
on the East Coast Onyx label) it was amazing."

You don't see that because composers generally don't hide quintuplets by 
adjusting the time signature.  Put anything intended for human musicians into 
5/4, for example, and then you must subdivide the measure-- 3+2, 2+3, etc.-- 
because that's the first thing a player will want to know/feel when reading it. 
 So now each measure has some assymetrical subdivision.  Then any 
"anti-quintuplets" would have to be shown as tuplets (e.g., 4 in the space of 
5), which, even if there are fewer of them, would be unecessarily complex 
because common time is, well, common, symmetrical, and easier to subdivide.

With quintuplets, there isn't (or at least ideally shouldn't be) an implicit 
hierarchy of beats within the quintuplet.  I think that's why they are favored 
in late-Romantic piano music, like Scriabin's Prelude No. 1, Op. 15, to get a 
kind of floating, improvisatory quality in a melody against the underlying 
pulse.  The "anti-quintuplets" here would be everything that's notated in the 
standard fashion.

You see plenty of examples of what Kyle Gann, in his Nancarrow biography, calls 
divisive rhythm-- dividing a measure up into groups of 5, 7, etc.-- in 
Schoenberg and many others.  There was evidently a big divide between 
supporters of this procedure, and the additive procedure of Stravinsky et al of 
building asymmetrical rhythmic groups from a common small subdivision like the 
16th-note.  But for divisive rhythm, subdividing three or four levels deep 
quickly gets complicated and hard to read/conceptualize/perform/etc.  Many of 
Stockhausen's early scores (ab)use this degree of complexity.  He and others 
from the 50s evidently didn't find the need to stick strictly to one type of 
asymmetrical division, however-- there are triplets, nested in quintuplets, 
nested in whatever.  But who knows, maybe there's some integral serialist 
"pioneer" out there who decided to break with convention and write a piece only 
using nested quintuplets.

Henry Cowell divised a system of notation for things like "fifth-notes" in his 
book "New Musical Resources" from 1930.  I think he actually used them in 
Quartet Romantic, though I haven't seen the score in a while.

What is the nature of the rhythm you're trying to grasp by ear?  If it's rhythm 
within a common pulse that divides strictly into subdivisions of fives (instead 
of twos), I don't think I know examples of any music that do that.  But it's 
intriguing to think about some kind of dance music being written with this 
constraint.

What I have heard are a) quintuplets to notate an independent tempo in a 
multi-tempo context: Elliott Carter's "A Mirror in Which to Dwell" b) 
quintuplets as obsessively/excessively written-out rubato: Ben Johnston's 
"Sonata for Microtonal Piano" and c) tempo ratios like 4/5/6 in Nancarrow's 
Study No. 49.

There's also the music of Brian Ferneyhough, which I don't know as well as the 
others.  But it's basically divisive rhythm in which long pulses are divided up

I didn't say that quintuplets don't happen!

I mean that quintuplets are relatively rare, and they rarely are used that 
much in one piece. You could take a complete piece of 5/4 and write it 4/4 
and it would have quintuplets all over, and so you could take a piece that 
is mostly made of quintuplets and disguise it as a 5/4 without 
quintuplets, but if it wasn't all made of quintuplets, then the result 
should have some kind of anti-quintuplets, that is, multiplying the note 
durations by 1.25 times instead of 0.8 times. But I've never seen this in 
one notational form or another. Independently of how it's written, I've 
never heard it either.


So, there is this asymmetry whereby you can find plenty of patterns of 
accretion of durations in multiples of 5, but not much splitting of 
durations in multiples of 5.


I'd be glad to get references to specific pieces that contain a lot of 
quintuplets. Of the five composers you named, I only heard Nancarrow, I 
only heard of Nancarrow, and then, I don't recall any quintuplets in it, 
but I didn't see the score and perhaps I couldn't grasp the rhythm of it

It reminds me, I once applied in music composition at UQÀM, but when they 
sent me a letter telling me they wanted to test my piano skills with sheet 
music, I didn't reply, because I don't have any piano skills and can't 
read sheet music in realtime. The only instrument I was really ever 
proficient with was ScreamTracker, and boy did I abuse that thing. I made 
pieces in 21/8 time and whatnot. I found that notation much easier to deal 
with than classical notation... except for making quintuplets, that is.

You can also split note durations using a 2:1 ratio (2/3 + 1/3) and/or

There is music in 9/8 time-signature, and there is also music in 3/4

You can also find music in 5/4, 7/8, 11/8, 13/8, 15/8, and many

Make a random recursive partition of the fixed value, then shuffle it.

For example:

* start with the list 16 (one element)

* for each number in the list, throw dice to figure out whether you will
  replace it by two equal numbers. any new numbers shall have the same
  procedure reapplied to them (recursion), else I wouldn't be
  explaining it by saying "for each" when it's about a one-element list.
  this could give you, for example: 4 1 1 0.5 0.5 1 2 1 1 0.5 0.5 1 2

* a fair shuffle could give any sequence with the same number of 0.5,1,2,4 
elements in it, let's say 0.5 4 1 1 0.5 2 1 0.5 2 1 0.5 1 1.

maybe i should explain a bit more... the list is thougt as a sequence in 
(ms)values.
i use the length of a master sequence (ms) and divide it by these values 
( 2, 4, 8, 16, 32).
now my idea was to use random and gate to trigger the different results 
of the division into a new slave
sequence, the list. so the length of it depends on the random values...

thanks.j

I don't know if I understand correctly what you mean, but maybe
[list-equalize] from the [list]-abs collection can help. It scales all
elements in a list so that their sum is 1. 

If you add a new element into the list this will change the value of old
elements in the list of course.

[PD] list issue

2009-03-04 Thread YOhannes
hello,

ive got some trouble with list handling, maybe somone can give me a hand.

i like to group an unnown number of floats in a list. (these floats
are the result of different divisors, used all for a fixed value. like 
100/16, 100/32...)

what i want to do is to put them randomly into the list as long as the 
sum of all items
in the list equals the size of the fixed value. this seems to be pretty 
difficult...since i use
random i cant know what the next float will be.

how to handle that?
any experience with that issue ?

thanks,
johannes
