I studied trumpet from ages 11 to 17, and am now picking it back up at 40. As I cannot afford private lessons at this time, I hope to rely on this forum for answers to some basic "get me going" questions: 1.In picking the horn back up, I noticed a tendency to center the mouthpiece more on my lower lip, especially in the upper register. I recall that this may have been a problem in my past and I don't want to repeat the same bad habits. Any views on proper mouthpiece placement? 2. I've heard that one should be able to play the horn with it "laying on a table" (i.e. no pressure) and it seems too much pressure was a problem previously. How important is this and how can I alleviate it? 3. I've been "buzzing" a mouthpiece to and from work, but don't want to develop any bad habits. Is "buzzing" generally encouraged and is there any thing I should concentrate on? 4. I learned with and have always used a 7c mouthpiece. I'm curious if another mouthpiece might be better suited for me. Any guidelines or resources regarding mouthpiece selection? Thanks in advance for your help.
