This past year i went to a state solo & ensemble competition and i played Rustiques by Eugene Bozza(beautiful piece) and i played it rather well, getting the highest score. When i was done playing the piece for the judge the only real comment he had for me was regarding my embouchure movement. He told me that i sounded great but that the mistakes i made were because of a lot of movement in my facial muscles when i'm playing. He said that it wasn't so much when i was moving into the low and high registers but when i was playing notes within the same register. Afterwords i looked into the mirror when i was playing some Clarke exercises and i could definitely see what he was saying. Once i got to a certain speed in a moving line it became harder and harder to play; i felt like i was having to adjust my face to a lot of individual notes. I was just wondering what everyone here would recommend for limiting my movement when i'm playing and if anyone here had/has a similar problem.
