Re: How do I tune to a guitar
I play a lot of blues and classic rock, so I play with guitars often. Being that the alto is in the key of Eb, you need to transpose to whatever key they are playing in. Just subtract 3 steps. If they're in C, you're in A. Here maybe this will help.
Some of these fingerings take practice. Our band does a lot of songs in A, G, and E. Those keys are well suited to guitar and vocals.
