I have made far too many errors when transposing music for horn players over the years. As a guitar player, C is always C -- except of course when we're using a CAPO. Try explaining that to a sax player.
Tenor sax wants Bb charts and baritone sax wants Eb charts. I always seem to mess up the Eb charts so here's a handy transposition chart I've made for myself which some of you may find useful.
