Show HN: A piano chord-switch practicing tool I made

There are now many tools to learn chords. Here is one I made: https://chord-quiz.netlify.app/

You can connect a MIDI keyboard. It is open source: https://github.com/klavinski/chord-quiz

Looks interesting but I’m not sure how it’s supposed to work; at least, it does not seem to support touchscreen devices at all.

I just added mobile support, thanks for pointing that out. Basically its to help practice chord switches - you provide a list of chords and press Start and it will present a chord from that list and give you a set time to play it in. Then it plays the chord itself and you can see if you got it right.

Okay, that's basically what I figured, but it's not clear how you are supposed to input the chord - does this assume you have a MIDI device connected to your computer?

Just a fun little tool I made during a Christmas flight. Happy Holidays!

Very neat, thank you! This could be very handy.

Is it open source? I would love to have the ability to display intervals instead of note names (maybe both?).

It is open source! It’s on GitHub at github.com/aliabid94/chord_practice
