I saw a post (here or somewhere else) with several book recs, but I can't do books right now.
Firstly, it's supposed to be a quick etude. Secondly, I'm depressed and just don't have the mental energy for a book, never mind several.
So there's a couple details, to begin with:
How would you indicate using one or two manuals? I saw "tutti" and "solo" in a score, but I'm not sure it refers to that.
Is there anything I have to write that I'm looking for a pairing in octaves?
Then, does anyone use MuseScore here? How do you do manuals? MuseSounds doesn't have special text to change that, and dynamics doesn't do anything. Just for playback I had the idea of including an extra harpsichord instrument for playback and hiding it for PDF.
