Saxophone Transposition

Why am I in a different key to the rest of the band?
This is a very common question, especially from anyone who has just bought a saxophone, taught themselves a little bit and then decides to play along with some other musicians. It can be a big shock to discover that the piano player, guitarist, bass player are all playing in the key of C, but when you join in on your alto or tenor, YOU ARE IN A COMPLETELY DIFFERENT KEY AND EVERYONE IS GIVING YOU DIRTY LOOKS. Welcome to the world of saxophone transposition.
