Well, B for sure is not the horn players key of choice, but surprisingly, F# is not bad at all...

You have to remember that tenor sax and trumpet (and soprano sax) are all Bb instruments, so when you are in F#, they are playing in Ab, a pretty good key for a horn!

But playing horn (I play trombone) with a lot of guitar bands, you get pretty used to playing in a lot of sharp keys! If only guitarists tuned a half-step flat...
