Okay, I have been playing Trombone for five years and I want to learn to play Trumpet too. I DO NOT want to switch to Trumpet, I just want to learn for fun and because I have to teach the younger kids below me. I play Trombone for marching band, symphonic band, and jazz band. I do not want to change that, I just want to learn Trumpet to help others and thats it and MAYBE play it for Jazz band 2. (We have two Jazz Bands at my school). Now my question is, if i learn to play Trumpet, will it hurt my Trombone embouchure?
