Pedal tones get way too much attention after all we can count on 1 hand how many times they have been played in public.

My views are based on having to fix other teachers problems. Time and time again I've seen pedal practice lead to an embouchure shift or evenlip damage if used to revive tired chops.

I never said that they did not work. I said that the RISK involved outweighs the benefits.

Today I was advised to alter my embouchure to play lower pedals inorder to increase my range. In order to give embouchure advice you have to at least know what embouchure the 'student' is using. BTW I have played Pedals in public.
