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

I'm building a video conferencing app designed to facilitate better remote piano lessons. My hope is to solve a lot of the challenges piano tutors and new students deal with when taking lessons through Skype/Zoom. It leverages WebRTC's data transmission to send media, MIDI state, and (eventually) send sheet music files and other musical data. I'm surprised with how well the MVP has worked and would love to hear any feedback or suggestions!

Hello HN, I just released this music theory and ear training mobile app for guitar which I've been working on for a bit more than a year on the side. The idea was to make something for the eternally "intermediate" guitarist (myself included). There are a lot of beginner apps which rely on learning songs, toolkits which give you a bunch of stuff with no explanation but not many in-between apps to actually learn and practice more generic and somewhat advanced stuff. The app contains short lessons, recaps and most importantly challenges (visual, audio and pure theory) along with a very complete…

This is a project I've been building in my spare time over the past few months. It's a library that provides methods for working with musical harmony ‒ intervals, notes, chords. For example, it can parse almost any chord symbol (Fmaj7, CminMaj9, etc) and turn it into notes, or it can identify a chord from a given set of notes. I started this project with the idea of using formal grammar to parse chord symbols. I wanted to use it instead of a hand-written parser, which is the common approach among similar libraries. Lua caught my attention because of Lpeg, a Parsing Expression Grammar library…

Pianolyze▲149Hey HN, I'm a pianist who's always been obsessed with understanding how great players think through harmony. What voicings are they using? How do they voice lead through changes? What's actually happening under their hands? Back in 2022, I built Harmonic Analyzer (https://www.youtube.com/watch?v=iNgSgvUmiOs) – a Mac app that used ML to transcribe polyphonic piano recordings. It got some traction, but I never quite finished it. Requiring users to download a Mac app felt like unnecessary friction, and I didn’t want to limit distribution to Mac users. I just shipped Pianolyze…
