Though I never had one (they are rare in France), it became sort of a pop culture icon. For me it was through the work of Rebecca Sugar on Adventure Time.
I always liked to play silly made up songs, so I made a silly instrument to go along with it!
If you want to listen to a true musician using it, I recommand Hijaq's work on YouTube[1]. He uses many other pocket instruments if that is an interest of yours!
Very interesting! It seems to be a great way to combine chords with scales within chords, something no traditional instrument can do. I see the key positions on the left is similar to a computer keyboard, perhaps it could be directly mapped onto a keyboard? That way it could be played even when without that hardware.
Wow, this seem great. I know pretty much nothing about making music, but I've wanted something that I can stim with that's nice and tactile, but also makes sound depending on how it's touched. I looked at Glo, The Polyphonic Whale, but never got one. I have an Otamatone, but don't like how I can't do more than one note at the same time (no chording).
Meta: This is a very messy title, it should just be "The minichord: a pocket-sized musical instrument" or something like that. We have the github info in the auto-generated blurb right after the title, after all. Thanks.
