Hola! I'm completely new to the forums, so bear with me. I'm a seventh grade trumpet player in band and I've recently notice my sound is edgy. At first I thought it was just the mic because I may have been overpowering it with how loud I was, but then I really noticed it when I listened to my Jazz solo. It sounds really obnoxious, and I'm pretty sure the mic was good quality. So I'm assuming it's a problem with me, but what do I do to fix this? I've even used my iPhone 3G mic to record my playing and it sounded pretty much the same as the solo at Jazz fest. Please help me! I really don't like how it sounds Now my next question is probably something I shouldn't be as concerned with, but I was wondering what exactly in the embouchure determines a classical tone or a jazz tone? I'd prefer to have a nice jazz tone, but I should probably have a tone that's flexible for both seeing as how I can't be in Jazz band without a normal band first. Basically, I wanna sound good is really all. Thank you guys for helping out!
