Re: Double-flats used by Lilypond after transpose

[Toine Schreurs]

The transposition of the instrument does not depend on the key of the
music. On a B-flat sax a written C sounds as a B-flat. That's all the 
information
you need. 

So use \transpose bf c' {the music}

And indeed, key E-major goes to F-sharp-major. The original transposition
from E-major to G-flat-major implies an A-sharp saxophone.
