There is no teacher. This is just for anyone who is in band and enjoys playing their instrument: brass, woodwinds, percussion or otherwise. However you must figure out my riddle: In the key of E flat concert, start on c. Go up a third (interval), down a fifth, and up a sixth. What note are you on? It is in lowercase and if it is a flat/sharp (not saying it is) write flat/sharp w/o a space.
