Speaking of music and AI models - something I thought of yesterday which is an application of AI that would be insanely useful to me is giving it an audio file of a song and having it spit out the chords. I've seen software that attempts to do this in the past but it's all been unimpressive and inaccurate in my testing. I'm still kinda ignorant with how these models work under the hood, and perhaps that would involve a bunch of new training on music that hasn't been done (and maybe that could be a difficult dataset to train on in terms of copyright). But I play piano, and I can play a song if given the chords, but I'm terrible at transcribing stuff myself. So I'd pay money for a service that does this.

  Just tried this out. The stem isolation is pretty cool, but looking at the spreadsheet of chords it spit out, it seems to miss out on a lot nuances of chords. The song I used to test was Again by Mac Ayres[1], which I compared to some tabs I found on Ultimate Guitar[2] which I've played and sound very accurate. The main 3 repeating chords, Ebmaj7 Gm7 Abmaj7 are close to what Fadr spit out, but it missed them being 7 chords. It gave D# Gm G#. Getting a little spicier with chords, there's a move where the Cm7 has the bass move down a half-step to Cm7/B. Fadr wrote it as a single Cm chord for the whole thing. That's the kind of thing that can be tricky to figure out. It kinda seems like it doesn't know anything outside of straight-up major and minor chords at all? Cause I don't see a single 7 in the entire spreadsheet, and that's not even that complex of a chord. Still a neat tool, and trying to learn off of a stem track would probably be easier than the whole ensemble. But I think there's tons of room for improvement in the space.
