How it works
Built around the three chords you already know.
1
Add your chords
Type chords or tap a popular progression like I–V–vi–IV.
2
Filter by genre
Narrow results to the styles you actually want to practice.
3
Play today, learn tomorrow
"One chord away" shows songs unlocked by a single new shape.
Under the hood
The frontend runs on TanStack Start with server-side rendering. Song search is proxied through server functions, so it can talk to the FastAPI recommendation service when it is configured, and falls back to a built-in catalog otherwise. Accounts, favorites, and ratings run on Lovable Cloud.
