[Harp-L] Vibrato Technique

[Wolf Kristiansen <wolfkristiansen@xxxxxxxx>]

More about vibrato; I'm not quite done.  What follows is predicated on 
agreeing that, in music, vibrato is a pitch change and tremolo is a volume 
change. If you don't agree, read no further.  

To my mind, no harmonica player can have a pure diaphragmatic vibrato 
(i.e. no contribution from any organ above the collarbone) for the simple 
reason that the diaphragm alone cannot affect the pitch of a note. The 
diaphragm can and does affect the volume of a note. Anyone purporting to 
demonstrate throatless diaphragmatic vibrato (what a mouthful!) is 
demonstrating tremolo, or, if a pitch change is heard, the player is 
involving his/her throat without recognizing it.  (Or involving at least 
the tongue and/or lips and/or mouth shape-- I think some players can get a 
vibrato without involving their throat).
