I’m facing a particular case which doesn’t seem to have a solution, but I wanted to know your opinion. I have a section where horns 1 and 3 are tacet and horns 2 and 4 are in the F clef register. This means that in the score I want those sections to be in the F clef, but in the parts, I don’t want the horns 1-3 to show an F clef. Both score and parts are transposed, so I can’t use the “show in concert pitch” trick for the clefs.
The only think I can think of is to put the f clef in Horns 1 and 3 use the good ol’ trick of hiding it in parts with alpha channel and size, and hope of or enforce no system breaks at that point. Is there any other option?
