During the interval at last night's village concert band rehearsal I had a quick look at the sousaphone player's music for the last piece and saw it was in the key of Bb. My cornet part was in G, so I thought to myself 'my part adds 2 sharps to this one, my instrument is Bb therfore theirs must be concert pitch (same as when transposing a piano melody to Bb trumpet).'
When I asked the sousaphone player about this he said no, the pitch of his instrument is Bb - the same as mine. When I asked why we din't have the same key signature I didn't get a very satisfactory reply.
From what I could see the Eb bass was playing the same part, and when I asked him if he was transposing he said no, so I don't know what was going on there either.
Does anyone out there have the answer?
Regards,
Mark.
