So I am making some changes in my playing and being patient about that but I am wondering if some dents in my horn are effecting my sound. I just feel like I have to blow a lot more then I used to and I feel like my sound is more dull then it was. I am trying to think back to when I dropped it and thats about about the time I noticed a difference in my playing. Im wondering if I just got frustrated at like a plateau of progress and I am using the dents as an excuse or if they can actually effect it. I have a small dent right in the middle of my lead pipe and then 2 fair sized ones at the bottom beginning of the bell (right where it connects to the valve) and directly above it after the curve of the bell.
