When I’m proofing parts I will find extraneous dynamic markings and hairpins. After cleaning up one part I’ll find that another part I had previously proofed is now missing the occasional hairpin or dynamic mark. Obviously, I’m deleting things that are grouped that I didn’t realize are grouped. It may be the result of copying and pasting sections of music from one instrument to another.
Does anyone have “best practice” suggestions for avoiding these kinds of problems? I’ve wasted a lot of time editing and re-editing.
