I am working on a score that goes between major/minor keys and open keys.
As a percussionist, I never really worried about keys so much, as I just played the notes on the page. But I am wondering from a conductor’s point of view/rehearsal point of view. With a score that goes back and forth so much, should I make a textual description that the music is now in an open key? Or should I just leave it alone?
I have been in many rehearsals where the conductor states, “Let’s begin at the key change after M”. This issue with this, is that if the instrument was in C (no sharps/no flats) at M, the open key after M doesn’t show an indication of a key change, other than the double bar. Currently I have been placing a boxed text stating “Open Key”, but I am wondering is this is really worth it or not.
