This book is a visualisation of a song I sang in my high school choir (https://www.youtube.com/watch?v=zZPYRHDKIj0). Each colour of thread represents a different voice part, rising and faling as the pitch changes, and each page is the equivalent of a bar.

I left the back exposed because every performance has its flaws, and even if though still sounds good it exposes what weaknesses the choir has.
