I freaking did it! I almost forgot, and I was about to get ready for bed but remembered I hadn't done the high E string yet. This isn't my favorite of the things I've played this week; the more I listen to it, the more it just sounds like a complicated 'Twinkle Twinkle Little Star', but at the same time it felt like the conclusion to something, so... fitting, I guess!
Thank you for bringing this challenge back around, Dominik!! This was such a great exercise!
