I'm trying to pick up some music skills, and part of that is doing ear training. Those who have ever tried it know that it starts with singing a bunch of stuff: just pitch matching, singing scales, singing chords, intervals, etc. Of course, the best way to do it is against a real instrument, but when you're especially bad at it like me, sometimes you want to practice with a tuner to make sure you're even hitting the correct pitches. Singing with a tuner is rather boring, so I made (yes, vibe-coded) a little browser game that is supposed to make it more fun. It's inspired by a TikTok mask with similar mechanics that went somewhat viral. Unfortunately (fortunately), I don't have TickTock, so I had to DIY it with a slightly different style.

Some gotchas: - It's very new, so, might be glitchy - Ideally, you want to sing with a drone, but it'll interfere with pitch-detection so, use headphones - It works on mobile (iphone), but I've seen some rendering issues. If encountered, try refreshing the page.

Otherwise, enjoy! I find the Random mode particularly fun.
