Actually, crooked teeth and lack of a music stand probably had more to do with my starting embouchure than any other factor. My left upper incisor is partially in front of the right upper. That for sure made me aware of the detrimental effects of pressure. I also used to point the trumpet not straight ahead, but slightly off to the right. This changed in 1997 when I started to play Monette. Maybe it was the mass of the Ajna2 that made me hold the trumpet differently or the fact that very small differences became very audible - or both. I don't know. I did become much more aware of my body use after starting to play that horn. Looking at various photographs of me playing, the trumpet position wandered to straight ahead (still angled down slightly) within 3 months and none of it was a concious effort on my part. The mouthpiece position on my face has remained unchanged.
