Listen and watch! If you hear sounds in the background (not music), that is most likely my valves. they do that a lot! WARNING: may cause problems for people with medical things by the fact of the flashing lights and rapide visual changes.
NOTE: sorry about the trumpet! It's not great, but I've only been playing for 2 weeks! ALSO, I've been playing baritone for about 9 months! I will be making a better vertion at some
