The Steven Universe music book Live From Beach City! came out today. It’s got sheet music, prompts to write your own music, related activities (like ‘design your own album cover’), and other cute activities (like 'create a fusion of you and a friend). It’s really super cute and informative (probably, I know nothing about music but I assume the chords they go over are correct).
Here’s a few pages and pictures I really liked. But the whole book is excellent, I just can’t take pics of the whole thing, haha.
