Spin up musical chord progressions in any key, hear them instantly, and turn them into songwriting prompts when you hit a wall.
This tool is on the way to the web. Meanwhile, Coco's app already trains the skill it's built around — free to start.
It builds chord progressions from music-theory rules — picking diatonic chords, common cadences, and tasteful borrowed chords — then plays them back so you can hear how they move before you commit. Choose a key, a mood, and a length, and get a progression you can actually use.
Songwriters use it to break writer's block, producers use it to sketch a section fast, and students use it to connect Roman-numeral theory to real sound. Pair it with ear training in Coco so you can not only generate a progression, but recognize what makes it work.
