Products that do what I made a tool for learning scales, chords, and how to combine them does
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 built a free, browser-based tool for exploring scales, modes, and their diatonic chords. Pick any root note and scale (major, natural minor, all seven modes, and 70+ other scales) and instantly see which chords (triads, 7th, 9th, etc.) belong to that key. It also includes a built-in sequencer so if you've found interesting chords for your scale, you can arrange them into a progression and hear how they flow together. No need to switch between a theory reference and a DAW just to test whether a ii–V–I sounds right in your preferred scale. No signup, no ads, no paywall, just a tool I wished…

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…

I'm excited to share with HN a new pet project I've been working on to explore how AI can create and explain harmonic chord progressions - Chord Variations. The project uses GPT-4 to generate unique and interesting chord combinations based on user input chord progression. It's akin to having a virtual musical assistant that can help non-musicians and musicians alike explore and create harmonious sound without needing any prior knowledge of music theory. The generated chord suggestions maintain a similar vibe to the user input. Alternative chord progression includes extended chords, chord…

Hi HN, As a beginner guitarist who loves guitar solos, it felt amazing when I improvised over a backing track with a pentatonic scale. I wanted to make it easy for any beginner to pick up the guitar and start jamming solos, so I put together Guitartonic. I plan to add more features as my personal learning journey unfolds, and I'd love feedback from other learners as well as experienced musicians. Happy jamming!

Hi Hacker News, I've created Chord Nebula, a simple web-based game designed to help users learn and practice piano chords, basic progressions, and harmony fundamentals. The game integrates with MIDI keyboards, allowing you to play chords in real-time and receive immediate feedback based on the key you choose. GitHub Repository: https://github.com/yottanami/chord_nebula Live Demo: https://chords.yottanami.com Requirements: To use Chord Nebula, you'll need a MIDI keyboard connected to your computer. Current Status: Chord Nebula is still a simple project. I'm…

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…

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,…

Hey guys I've been playing the guitar for many years but I felt like I had hit a wall and wasnt making progress. One of the things I realized was holding me back was unfamiliarity with the fretboard. I'd often find myself in situations like “Uhh…Where’s the C# here?” “Where’s the flat-3rd of this root on the 4th string?” “Sure would be nice to know the closest min7 triad shape to play over here..” I tried memorizing the fretboard the obvious way but it extreeemly boring for me. Being a developer, I decided to turn it into a game. I'd love for you guys to try it out and let me know what you…

Hi folks, About seven months ago, via HN, I got nerdsniped into a silly guitar transcription problem and made a bunch of really senseless code but what came out of it was what I thought at the time could potentially be pretty useful - a guitar fretboard mapper and fingering scoring algorithm. So as of yesterday morning I've finally put those bits of code to "good" use, creating gtrsnipe to convert between MIDI files (.mid) and ASCII tab (as well as VexTab and ABC notation) and any combination/direction among the set of formats. gtrsnipe tries to intelligently find the best neck and…
