Hi everyone, According to my band director and couple of members from the symphony orchestra I'm playing in, I have a very bright sound and tone quality. This is good for some pieces that need me to float on top of the orchestra, but for some pieces I can seem to get a dark or warm tone. Some one said that the brightness could be mistaken for my sharp pitch which I seem to have a habit of playing in. Is there anyway to fix my "brightness" in tone quality (which could just be because I'm sharp) through an embouchure change? I'm looking for a slightly darker, richer, or warmer tone to my classical playing. If the problem is due to my pitch, should I just keep pulling my tuning slide out even more, or should is it due to the numerous dings and dents that riddle my trumpet bell (thank god none of them are on the leadpipe)?
