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'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!

Haxophone▲526I built this during Covid. When I released it, some of the parts went out of stock or skyrocketed in price, no longer making this an economic DIY project. Now that things are getting back to almost normal, I thought I'd share it here and request feedback. This is a very niche project for people who like the same things I do: saxophones, Rust, mechanical keyboards and the Raspberry Pi.

This is a keyboard in just intonation. It can play the notes a piano can. The big difference from a piano is that all the notes become consonant. At least, when you want to play a dissonant chord, you are clearly opting in to it because it's clear which notes are dissonant to each other. You won't bump into a dissonant note by mistake. You can play without knowing any music theory. Hit arbitrary notes with the rhythm you want, and the pitches will work. Not understanding the buttons is fine. Even rolling your elbow around your keyboard is fine. If you are a musician and press the wrong key…

Originally started as a project to restore patterns from now defunct website 808.pixll.de just for myself, but eventually i decided to share it with others. I've seen this website mentioned a couple of times on HN:) Currently it only supports Roland TR-808, but there will be more.

I made this as a side project because I've always loved music but never had a real instrument or lessons. It started as a simple piano to play online, but grew into something more: - 100% free, no installation or login required - Multilingual interface (EN/ES/PT, more coming) - Works on desktop and mobile - Step-by-step mode to learn songs interactively Try it here: https://pianoeletronico.com.br/en It’s not professional software, just a free and fun way to make music. Feedback and ideas are very welcome!

I always found sheet music way too hard to read - and I literally spent a year at a company building a sheet music rendering engine. I wanted an app that would display music like the tutorials on YouTube, but not be focused on upselling lessons etc. like most current apps, and also would let me import my own files This works on MIDI files. If it’s a valid midi it probably plays. Since releasing, I did add a subscription for classical music - on a theory that most normal users don’t know what a midi file is. It changed about a month ago from an up front price to in app purchases and/or a…
