Greetings!
So I've been notating a piece for my son's school band (junior high). Copying the music from paper into LilyPond using Frescobaldi. And now I hit a wall. The music piece is written for french horns in E flat pitch. But the band's horns are in F pitch. I need to transpose the score appropriately. The band director expects staff with three flats (E flat major). I hope there's some easier way to do this than me manually re-writing the score. And I am not even sure how to do that. I would appreciate any help.
