   Dear Mimmo,
   No problem at all about the duration of sound with your strings. I
   agree with Bruno Cognyl-Fournier : we are all very grateful -  or we
   should be -  for your brilliant a d continuous efforts to improve the
   quality of synthetic strings and the discussion about Mersenne and all
   that is only a way to satisfy our scholarly egos ð!  But please keep up
   the good work and thank you again for everything you do to help us
   pluckers to improve our performances of early music!

   Best wishes da Francia,

   Jean-Marie

Fascinating thread! I am delighted that after over 40 years in the
lute "business" (even mostly amateur) that good bass strings may
   be
emerging as an obtainable, affordable,  predictable, and PRACTICAL
reality. Mimmo Peruffo is to be congratulated for all his work

all these years.
Now, can anyone tell me if the new basses are now  available in
   the
U.S?

[LUTE] Re: Aquila Loaded Nylgut sustain

2017-01-09 Thread John Mardinly

Huh? Folks, sound and vibration are one and the same. If the string can
be seen to be vibrating and you can't hear it, it is either a problem
with your hearing (which to be sure comes naturally with our advancing
age), or there is sufficient ambient noise in the room or other notes
being played that the sound is overwhelmed. You can be sure, that if
the string is vibrating, there IS sound, whether your ears/brain sense
it or not. The attenuation of the vibration follows a mathematical
formula (exponential decay) that is related to internal damping and
parasitic loss (which is energy transferred from the string to the body
of the instrument). Attempting to ascribe a single time duration number
to the sustain is an absurdity that violates the laws of physics. You
can use a single number to approach some convenient threshold, say for
example 75% attenuation (time to 75% reduction in volume), but 100%
attenuation is something you would never be able to determine with any
useful accuracy. Rob's video shows that it seems relatively easy to
âqualitatively' assess the difference in sustain, but to put numbers on
it, you would need to decide on some terminating threshold, and realize
that the string is still vibrating and there is still sound beyond that
terminating threshold.

Not sure about that Mimmo... Mersenne is a scientist, therefore a
precise observer and his observations are worth considering seriously.
When he describes the duration of the sound of the bass stings of a
lute, he takes care to precise ""...le son des grosses chordes de Luth
est apperceu de l'oreille durant la sixiesme partie, ou le tiers d'une
minute...", the sound is preceived by the ear for 10 to 20 seconds. And
a few lines further he says : "...Il n'y a nul doute que la chorde se
meut encore long-temps aprÃ¨s que l'oreille en perd le son..." = there
is no doubt that the strings still moves a long time after the ear has
lost its sound. So he is not confusing vibration and sound, not at all
!
Now, as Matthew remarked, we don't know about the conditions in which
the test was done. If the lute is laid on a table, it might certainly
influence the parameters of the experience...

I am lucky: I have seen /installed strings on some hundreds od
lutes in
these last years. Maybe I can be in mistake, but I have never seen
a lute,
whose basses are roped strings or even loaded roped strings, whose
sustain
is so long. Even with modern Pyramid nylon wound strings (they have
in
absolute the higher density) .
I would like to know if here there is somebody that can have a
positive
experience in matter. At present I would stick that Mersenne meant
how
many time last the vibration, not the sound.

One thing nobody seems to have mentioned is the vast differences in
sustain
from one instrument to another. Maybe Mersenne's comments go to show
just
how good some lutes were at the time. If one was to rest a lute on
the edge
of a wooden table as they were wont to do at the time, then maybe
those 20
seconds are not so unrealistic.
