fata760 It's not just for my own playing!
Ahh, that makes sense. Although, ultimately, if it clearly communicates the musical direction, I think it should be fine. No one would misinterpret or overlook what you drew in.
But, having said that, if you want something that doesn't look drawn, maybe there's a score reader with preset annotation stamps? I think forScore has stamps, but I never use them.
Are you using an app like forScore?
Oh! Actually, I bet you could do it in MuseScore, but with the learning curve it might not be worth it unless you do this kind of thing regularly. Also, you might need the paid version, I'm not sure. If you're interested in MuseScore, you might make a thread with that in the title.
Re photo posting, yep, ease of sharing photos is one of the great things about PT!
