Hi!!! I just wanted to say something. On piano, an easier way to explain a chord is that all are made of two consecutive tetrachords. And something kinda weird is that I have my own arrangedment of Mad World. It's an awesome story!!! =D
I've only read the first few chapters to far, but this story appears to be awesome. I love how it feels as if you're looking in on another kind of life, and I think you wrote this very well. Keep up the amazing work!
