Hi Greg. Here is a quistion not to be asked but again it has to. Some years ago I was playing High C to high E. Then I played too much...everything crashed. Then I had a surgery in my top lip...to times😢. I used Balanced Embouchure and that was great for me at that time. Now I can do G and A above staff, but do play 4'th in a couple of bigbands. Soloing but that is not my goal...I want to be heard and want to be able to have peoples eyes lift when I do solo...and for that I need better tone, more volume and a secure higher register. As you guess I am a happy amateour but want to play easier and in my way. So: (here is the quistion not to be asked but then...) If I stop playing in band(if that is nessesary) to get into the way you advocate, and do play for about an hour a day...for how long time will it be nessesary to do that before the new embouchure is ready to play in band again? If I do use shape you say and not force air I can do low C to G above staf ok but in band, it is all over the place of old, between and new... After that G....pffff...NOT Coffee time! Perhaps we have to meet via Skype? Take care Erik Denmark PS: Sorry for my spelling...my spoken english is better...
