I'velearned not only in music, but in any cohesive entity whether it be a sports training company or a frat withhold secrets for reasonable purposes. However, music in my opinion is not really supposed to be competitive, because I believe it is more so about honesty,communication, soul etc. but I'm finding that people with-hold trumpet secrets ; I don't know whether its the old selfish "find out for your self .. I had to thing" or more so a coltish thing like "your not my brother thus, I have nothing to tell you". I don't believe in such things, I haven't been playing that long but I'm glad to share just a few things I learned along the journey; feel free to share "your secrets" or things you overcame that were difficult, because of course getting a sound out the horn and figuring out how to play scales isn't really secret if you have a computer-teacher etc. But other things are a bit more difficult to overcome. A jazz trumpeter revealed that improving his tone was partially attributed to playing in corner walls in his home as they amplified his sound so he could listen to it better. if you watch miles davis play alot of the time its pointing to the floor and other directions, its because he was obsessed with how the sound of the notes changed as he pointed it in different directions. Most of you already know that high notes actually require less air but faster which requires compression. Maynard Ferguson got a boy who couldnt play high notes to point is horn to the ground which gave him the leverage along to the concepts I just alluded to play the high notes. Alot of little things like this helped me improve my playing. Does anybody have things/moments they recall that unlocked a personal trumpet mystery/problem?
