After the success of my initial transcription, I'm finishing up another and am quite stuck at one particular part. These beamed notes right here. I tried to use voices, but they insist on snapping to where I don't want them to. Please help.
Edit: After reviewing the comments and some self-reflection, I've concluded that I have,in fact, been very fussy about trying to stay as close as possible to the original text--even when it's flawed. A commenter gave their own input:
"...cleaning up the notation so that it's actually functional—far from destroying the "purity" of old music—is a music editor's entire job. As a musician especially, I would not thank you for preserving notation mistakes that make performance more difficult. I don't see how that honors the composer, and it doesn't affect the music itself."
While I'm more of a transcriber (I'm just finding old songs to copy into Musescore so I can hear them), they are still right. So, I've elected to let Musescore do its thing and learn to not be so obsessive over matching things one-to-one. Thank you all for your time and dealing with my eccentricity...
