Awesome. I'm trying to pick it back up and go further, and I realized that sheet music bores me and I want to try just finding chords of songs and banging them out. Relatedly, I ended up making a very kludgey tool (in bash, ASCII graphics) that would let me enter a few chords and would cycle through them with on the same screen-piano-keyboard (e.g. to better see the "transitions.") I'm kind of surprised I've never seen anything like that out there done more formally?
