Pretty cool. It’s nice that computing the good fingerings takes a while, makes my brain feel less ‘out of a job’ that it can do that nearly real-time. Would be good to see some harmony and how the solver would deal with multiple notes at once.

If you’re seriously writing out tabs and need some software, I’ve been using Dorico and it’s pretty damn good. It gives you a medium grade solve and then you hit a few keys to move a note between the strings where it is currently playable.

I think in one of the algorithm lectures by Eric Demaine he outlines the idea of making a dynamic programming algorithm for good finger positions for chord progressions. Although you have to carefully design your cost function (moving the finger from one place to another is costly)

I did implement the one for normal notes and the extension to chords shouldn't be that difficult but the execution is instantaneous because the sequence is not that long.

I think I understand what you mean. A trained guitar player would not need such a tool, and a beginner should probably avoid using it :). My original idea was to explore how I could rapidly get playable tablatures of jazz solos from available sheet music that I still cannot read fluently.

Actually, a few tweaks and the use of optimization options allowed to dramatically reduce the execution time for my 20-note example.

Yes. I think it would take some effort to adapt the current set of constraints but it should be feasible.

Thanks for the tip. They don't seem to offer a Linux version though.

Check out Soundslice (https://www.soundslice.com/) for an excellent tab and notation editor. It’s web-based and hence works well on Linux.
