Intro - basics
Alto sax is a transposing instrument. Alto sax is in Eb meaning when it plays a written C it sounds Eb, a sixth lower.
If I want to have the alto sax score in Eb minor, I would expect the key signature of the sax music to be in Gb. (Enharmonically D# minor would have a key signature of 6 sharps - F# major). I can get Dorico to create a concert pitch A major score and a sax score in F#, but can’t see how to force it to Gb.
Has anyone an idea - please?
