I've always wanted to practice playing piano chords on my computer, so I built this simple game that gives you a random chord to play.

The game supports input from a computer keyboard, a mouse, a touchscreen, and even a MIDI keyboard.

There is a training mode that will highlight the notes to play.

You can also adjust the difficulty, the oscillator type, and the root note of the generated chord.

Built with React/TypeScript.

Hey bbx,

Nice job! Some feedback:

- Add a toggle that automatically plays the chord when you request a new one

- Consider getting a simple soundfont (guitar, piano) - it'll make the previews/playback a bit more natural sounding

Thanks for the feedback. The toggle should be simple enough actually. Adding a soundfont is also a good idea (I'd never heard the term before).
