I received this in an email from a trumpeter who began studying BE two months ago. Although it can vary greatly, it is typical for the BE student to experience notable improvements in embouchure function at the 2 month mark.
This is Erik. Just an update. My endurance and playing have improved dramatically. I actually have been doing BE combined with another method. I started with the other method a while back before I got the BE book you sent me and I just kept going with both. The other method is a collection of exercises with no emphasis on embouchure formation, so I think it works well with BE.
I was able to play my first triple high C last week (not very loud, but still was able to hit it). Thinking it was a fluke, I tried it again after a short break and was able to do it again. High C which used to be an "iffy" note for me is a pretty easy note, now. In performance, I am hitting high notes with confidence and power and the band and audience are definitely impressed.
I am determined to turn my previous weaknesses into my strengths. Before I was known as the guy who could play but was inconsistent. My goal is to be known for my consistency.
You mentioned to me before that I might be "thankful" that I am self-taught, and I see what you mean now!
Anyways, hope you are doing well. I will send you another update when I get further along.
Another thing, I am able to play almost any type of mouthpiece now. Before, I could only play big mouthpieces and would bottom out on small pieces. Now, I am playing very well on a 10 3/4 CW.
