When-in-Rome

For just chord analysis, there's "Harte notation", which is meant to be unambiguous representation of the notes (https://ismir2005.ismir.net/proceedings/1080.pdf). That obviously doesn't get you all of the additional information necessary for engraving and full representation of the music, but there are research datasets available using it like https://github.com/smashub/choco. I've also used the https://github.com/MarkGotham/When-in-Rome dataset for some analysis work, but again that's not 100% what you're looking for. You might like the "iReal Pro" app for the replacement and transposition of jazz standards on your tablet. It's pretty great for that use case versus camera scans.

Yeah, I see your point. You want same alterations on different Roman numerals to look the same. (In my current system b9 over I and b9 over V look different.) I briefly explored this appoach: https://rawl.vercel.app/edit?a=beethoven_op10no1mov1 (Although it was a mess.) In current Rawl terms I call it "annotate modulation at every chord". Back in the days I thought it's better. It turned out that: - You need to do tedious annotation. So you can only work with classical repertoire datasets like https://github.com/MarkGotham/When-in-Rome - Worse even, you need to look at two places simultaneously: to the score and to the string of Roman numerals - And worse still, all chords then look the same. The score itself becomes bland. Most of the time, if you aren't deep inside the jazz repertoire, there isn't that many alterations. So you'd mostly
