quite frequently (at least in arrangements for wind bands at school) cues are not only for knowing what happens, but they are also meant for “play, little baritone player, we will never have a bassoon in this band” or “play, saxophone player, our trombone girl is ill today”. At least in the latter case, I’d get a bewildered look and a helpless shrug because of the bass clef.
In cues settings I propose an option:
- clef change if needed (clef reflects the source)
- no clef change (clef reflects the destination)
