Gamified musical pitch recognition

What it does

A gamified way to develop pitch recognition. Daily challenges split into 3 levels of difficulty. In the IOS version, users get a pitch accuracy visualisation to know which keys they need improvement on. Don't know piano? Don't worry, there's a beginner mode to get you up to speed with all the keys. If you're competitive, you'll have fun climbing ranks in a League of legends inspired style leaderboard

    Perfect Pitch Puzzle – a musical Wordle daily ear training game2023 · perfectpitchpuzzle.com · ▲225

    Hi all! Thanks for checking out the side project my family and I have been working on (on and off) for the past year. We were playing wordle when we thought: wouldn't it be fun if you had to guess musical notes (ABCDEFG) instead of words? And what if the notes you had to guess were actually the first six notes of a familiar melody? My brother and I both have perfect pitch, which has been really helpful when we want to cover a song that we like, or improvise in a jazz or blue grass setting. We don’t promise that this game will help you gain perfect pitch, but it is possible to train your ear…

  • I trained a 125M model to autocomplete piano on-device17d ago · simedw.com · ▲598

    I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

    A tool for creating chord charts on the go2024 · tiniuc.com · ▲150

    Author here - one of the most notable facts about the app is that it's made entirely in Godot Game Engine! I think it's great for apps like this because it makes it especialy easy to iterate on GUI designs such as this one. Feel free to ask me anything about Chord Chart Memo, or my experience with Godot.

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
