I’ve searched the archive of posts but I don’t see anybody specifically asking this question; namely, Can I put in a clef change that only appears in the part or only in the score? This is a very common occurrence. For example, I’m working on a score that must stay in C but includes several F horns whose parts will obviously be transposed. There are several places where the score should switch to bass clef for low horn lines, but the part should stay in treble clef nearly all the time. (I believe Elaine Gould suggests keeping the horn in treble clef down to a low C.)
Does Dorico yet support this?
(Yes, I can imagine a workaround: make new players with identical music to the horns in question, remove the clef changes, remove the new players from the score, and use the parts these new players create. This is kludgy and removes the benefits of having parts linked to the score; it’s also good recipe for a mistake creeping in to either the score or part and never getting corrected.)
