I have come along over the years but still find myself biting too much when playing the alto in big band high and loud. I think I have bad instincts and want to work with the embouchure muscles when most of the work really should be on the air support. Intonation then becomes more of a struggle than it should be and the tone is not as full as I wish. Any suggestions on how to overcome this most effectively? I have studied with a Joe Allard student which has helped but there is more progress to be made.
