How it works
Build with musical parts
A block is a small musical move: repeat the motif, answer it, add a bass floor, walk away, or come home. The whole phrase is just those choices snapped together in order.
Try these
Start with Motif A, then Echo. Does it feel like a call?
Add Bass Floor before Ending. Does it feel more settled?
Move Bridge before Motif A. Does the phrase still make sense?
Why this lab
Kids compose by arranging reusable musical ideas. That is closer to real composition than pressing a generate button: choose a part, hear its job, then decide what comes next.
