I've worked on this problem for some time on a personal project, and I'm pretty convinced you can basically solve this problem without deep learning or AI techniques, and instead use non-negative matrix factorization[0] as a bank of note templates (from their spectrograms). I have a fairly well working proof of concept and the approach is supported by the literature. [0]: https://en.wikipedia.org/wiki/Non-negative_ma…

This is the right approach for song recommendation too — try your approach there and see what happens. If you want help on the business side, reach out.

Against my better judgement I actually logged in with Spotify, only to find that it just didn't work. I'm not really sure what I was expecting anyway. There used to be a great trade in guitar chords online, but then lots of small sites got taken down and ultimategyitar tried to put a big shitty paywall around years and years of high quality content made by volunteers and often scraped from other sites.

Seriously ultimate guitar just effed over so many people who put time and effort into spreading guitar chords. That and their site is covered in so much ad content.

You would think getting the notes and converting them to chords, and tablature, would be one of those "exactly suited for neural nets" type of problem. If you want the chords to "Here comes the sun," you can find dozens of hits, but try something slightly obscure and they are hard to come by. (People with great ears have no idea what I am talking about.)

As an amateur musician I see this as a missing holy grail killer app. I'd love to have it just to pull the chords out of some of my own old recordings that I can't figure out how to repeat. If anyone knows of any apps (even prototypes) that can do this, please provide links.
