ahhh silly me, that's an off-by-one error - i had one less note in the music scale than the number of boxes.

Further improvement ideas: We should just just use https://tonejs.github.io/ here. It'll sound much better 🤓

Right, I shouldn't have include 12 (which is basically the same note as 0). 😅

I was just looking at that too... looks tone.js can do a lot if we are ok with pulling an extra dependency

Yeah, that's not a problem. We should definitely up our game sound-wise.
