I'm supposed to be teaching a brass sectional for a local high school later this month. Seeing as I'm just a trumpet player, and fresh out of high school, I thought that I might read up on some other instruments' characteristics. I'm currently writing out some technique builders and some range exercises. I know what works for me, but I'm wondering if other brass instruments follow the same rules. So is concert Bb the same fingering/slide position as concert F, concert Bb (up an octave), concert D, etc? And are there any things I should know about low brass before I teach them basics? One thing I definitely DON'T want to do is teach someone wrong.
