There is vertical phase difference and a large closed
quotient in male head voice and also the shape of the
electroglottograph signal is the same as in chest voice.
The folds are longer and thinner, but I see no reason to assume a
register event in the vocal folds themselves, nor a mix of two
registers, but simply an extension of the same vocal fold
vibrational pattern seen in chest voice. The registration event in
a well trained male voice takes place exclusively in the resonance
adjustment. >>
wim,
this is my understanding as well. i would go on to say that there
should be, given your description above, a constantly varying timbre going
from low to high and that the notion of registers is purely psychological and
not physical. in putting new strings on a guitar, as one stretches the new
string to the correct pitch, the timbre of the string changes as pitch is
increased. when a tape of a voice is sped up, there is a timbre change.
i don't know if you have ever tried vocalizing while muffling your sound
(by covering your mouth with a towel, for example) but, in doing so, and
thereby reducing the amount of sound feedback you receive from your voice, it
is remarkable how easy it is to go from low to high (i think lloyd even
talked about using paper towels, in such a fashion, to help male students
find their head voices).
as i have suggested before, the sound of an efficiently produced voice
may not be desirable for the singing of one's art. and therefore, the goal
of all singers in learning to sing, is to figure out how to produce the sound
they want, not how to produce the voice most efficiently.
