I made a tool for learning scales, chords, and how to combine them▲36
This started out when I vibe-coded a guitar scale fingering generator. It came out pretty good, and I started adding stuff to it: chords, then how chords and scales interact. Then I added charts for other instruments I mess around with: piano, cello, alto recorder. There's a complexity toggle to go from basic harmony to extended/experimental stuff. It's honestly still mostly a toy, but I thought other people might be interested in playing with it. Source is on github, so it's easy enough to run locally and fork. https://github.com/aleshh/gtr-scales

A free tool to visualise scales on a guitar▲27
Hey everyone, I wanted to share something I’ve been working on that I think could be really helpful for fellow guitarists. It’s called StringScales (https://stringscales.com), and it’s a free tool that I built because, honestly, I've been able to learn so much about music on the internet, and I wanted to contribute something useful. It started as a personal project. I’ve always felt that a lot of the tools available for guitarists could be better... more intuitive, more accessible, and without the constant need to pay for basic features like CAGED or 3NPS position highlighting. So,…

See chords as flags – Visual harmony of top composers on musescore▲129
I designed a relative piano-roll-based music notation. I used 12 colored arranged in a specific way to make visible the main effects and oppositions of Western tonal harmony. The tonic is always white, so a manual annotation/interpretation is required for each MIDI file. All chords are flags of three to four colors. Minor mode is darker, major mode is lighter. Colors are arranged in thirds. I sorted the pieces from simple complex harmony. I also wrote a bit of text to explain what you may see. There's also a corpus of structures: hyperlinks of tags that allow you to find similar…
