[Trombone-l] Embrouchure problem--help for a friend

[mcclurefamily@srt.com]

Does anyone know of an email list for trumpets?  Or a specialist
who helps players with embrouchures?

I have a trumpet embrouchure question on behalf of a friend. This
friend can play for a while then the muscles on the right side of
his embrouchure just quit. Some tingling, no pain, some numbness.
 Just no support, almost randomly. 

makes me think of Bell's Palsy, or Sling Palsy from my Marine
Corps Days (rifle range).

Any ideas? He is so frustrated...he doesn't have ANY bad habits
in his performing or practicing and uses the no pressure method
of playing already...plays on a Bach 1 (the largest trumpet mp
available). 

Please share anything you think may help. Or point me to other
sources. t5

Doublers, what say you?
