lately, i have been thinking about how the resonator (vocal tract)
affects the vibrator (larynx). while i think it is possible for the larynx
to work independently of the vocal tract, as they are connected, radical
movement in the vocal tract surely will have an affect on the behavior in the
larynx (as pointed out in titze's article on 'the raised and lowered
larynx').
when it comes to head voice, my understanding of head voice is largely
in regard to what is occuring in the vocal folds (an increase in
crico-thyroid activity with a lessening in activity in the vocalis muscles).
what i wonder about is, does this change necessarily have to affect how the
vocal tract responds to the new vibrational pattern? of course, it does
but, does it have to change in a particular way or, is there a wide variety
of responses? for example: the spread ugly sound of jerry lewis singing
high notes - is that necessarily chest voice or, is it head voice with an
ugly use of the resonator? or, is the vibrational pattern of head voice so
distinct, that only a few definitive sounds can be considered head voice?
if so, is this true for all voices, equally?
if the answer is no, to the last question, what about the very light
tenor? does his voice behave more similarly to a female voice than to a
bass? every once in a while, i come across a tenor whose voice didn't
change over night (the way mine did). instead, their voices got gradually
lower over the period of as much as two years. these guys usually have no
break or, falsetto.
