Hi, I recently switched teachers, as my old teacher moved away. However, there is a big problem now, because the techniques my old teach taught don't agree with the new teacher. One of the biggest problems is resetting. My old teacher got me into a habit of resetting the mouthpiece whenever possible. Even before, I thought this wasn't exactly right, but because me teacher explained, how it would help tone and range I did it. Now, my new teacher says it's bad, but I can barely play a few lines without having to reset. I think it is because I have always played with moderately moist lips, when I reset, I clean off the extra accumulated moisture and play again. If I play continuously, moisture builds on my lips, and the mouthpiece slides and my lips are having a hard time staying together or keeping still. What should I do? Also, my range is still the same. Since I started trumpet three years ago, the first year, my range expanded up to a g on the top of the staff, then it just stopped. Over two years, I have gone to three teachers, and each hasn't been able to help me with it. The first told me that I wasn't practicing range, so he gave me long tones and other exercises. I had worked on them for a couple of months and it was the same: some days, I could get around g and work up a few notes, other days I could barely play a good c or d. The next teacher, told me it was because of braces, however, I had stopped improving five months before I got braces. He was the one that told me to reset. What he did was tell me to keep a good embrochure and practice being consistent with my setting and air. My current teacher, has been also saying it is beacause of braces, but he is more concerned with air and breathing. I have also problems with tone quality, and tonguing. At the top of my range (above a c third space), I have a lot of trouble getting the note out when I tongue. If I slur is, it is fine. My teachers have told me to say tu and ta, but it still doesn't work. The main problem is inconsistency. All these problems show up one day, and another only one, and another day none. I am so frustrated and even have been thinking of quitting. Please help!!
