In band class today we were listening to the recording of the concert that we had a few nights ago and one of the things I got hung up on was my bright, almost nasally sound. It was especially prevalent during high passages (which, just my luck, were all over the place - yay, lead playing!).
I spoke with my band director and she agreed that maybe my sound could stand to darken up a bit.
Unfortunately, she's a clarinet player, and only generally knows how to make a trumpet sound darker. My jazz band director, a trumpet player, was out of town for a conference and my private teacher's in New York.
I need some advice - what's a good way to darken up my sound? The only info I really have to go on is drop my jaw and think "OH" when I'm playing. Do you have any suggestions as to how I can make my sound darker on the "software" side of things?
