I am a novice trumpet player returning after thirty years of not playing. I have been researching information concerning embouchure and practice techniques. I have been studying music theory and trumpet playing for about a week now. I find the above advice clear, concise, and and I will be following it. After thirty years of not playing I was able to play two octaves, C to C, from memory and actually hit the top C the first time I pick up the trumpet and it sounded ok (in tune)—not loud and not brilliant but ok. I was way relaxed and no pressure was on me to play. I started pushing myself and straining to play better right away. That didn’t work for me I could not play the same C to C scale after a few days of not so smart practice/playing. Thanks to TrumpetMaster I will be a better player.
