yes.

i guess so. i tried to get that oscillation to stop and i couldn't do it but, i can increase it without oscillating (visibly) the fundamental. (this is using a spectral analysis program.)

I thought that that was the situation for vibrato. It certainly is in the case of a stringed instrument, in which the vibrato is produced by slightly rolling the finger that stops the string. >>
whatever we call it, there is a difference in what we'll accept from a voice and what we'll accept in a stringed instrument. what you describe as 'vibrato' in a stringed instrument, matches my description of 'tremolo' in the voice.
my guess is that the terms existed and have been used long before we were capable of knowing exactly what is happening.
