Great, thanks to both of you! Very clarifying. \transposition is, thus, going in the direction of instrument -> playback, whereas \transpose goes in the opposite direction, if I understand it correctly.
I do a lot of brass stuff. And as you've realised, it's \transpose not \transposition.
I just think "\transpose for printed music, \transposition for midi". How accurate that is I don't know.
The other trick I always use (given that a trombone plays both bass clef in C, and treble clef in Bb, and worse when you get an American bass part in Bb ?!?!?!), is I transpose on input as well as output.
When copying a part IN to lilypond, I'll wrap it in "\transpose c c" or "\transpose bf c'" depending on whether it's a bass or treble part. So I know all my music fragments in lilypond are in C.
Then I'll wrap them the other way on output to put them in the correct printed pitch. That way I never have to transpose in my head to make sure things are correct.
