I'm think your post has persuaded me I should buy this or perhaps but it in my letter to SantaWhen I first started playing fifteen months ago, I faced the familiar difficulties with high and low notes, poor stamina, inconsistent intonation and physical and mental tension while playing. Working through John’s book over the last six months has resolved all these issues for me. I am now able to play notes in registers 1 and 2 in tune with little effort and greater consistency. My playing feels much more relaxed and I have a feeling of intimacy with my instrument. Like a golfer following a clearly defined pre-shot routine before striking the ball, John’s method has given me a setup routine for body and embouchure which I trust to produce a consistent, clear note every time. I’ve very much enjoyed studying the material and putting it into practice and am confident I will see further improvements in the months to come.
