Resonance has its effect on "mix" by giving the singer control over
the which partials are allowed to be heard and how strong these
partials are in their relation to each other. Physically it is not
possible to mix a chest voice with a head voice because the vocal
folds cannot do both of these functions at the same time. But the
folds can migrate in their action between chest (heavy) and head
(light) and these gradual changes are strongly influenced by
configuration of the vocal tract (resonance). >>
lloyd,
logic says that if the folds are migrating, they are either doing both at
the same time or, doing something other than chest and head (in other words,
a third action).
you have mentioned the influence of the configuration of the vocal tract
having a loading effect on the vocal folds before, and now, you also mention
the effect of 'standing waves' on the vocal folds. i understand how the
configuration of the vocal tract can have an effect on the height of the
larynx and how the position of the tongue can have an effect on where the
epiglottis is. i don't know what 'standing waves' are and i only have an
idea, from practice, the effect that resonance has on vocal fold behavior.
a lot of confusion on my part (probably from experimenting too much with too
many different ways to sing).
so, are you saying that the events in the vocal tract have a 'back
pressure' effect on the vocal folds? and is this air or, sound or, both?
obviously, different consonants create different degrees of resistance, in
regard to air pressure, that must affect the folds, noticeably or not ( M and
B for example). but do the vowels have the same effect or, do they have a
different effect?
