@zanc_zhao You’re proper, chord lens is complicated in the beginning look and that’s on us. We’re including a brief explainer within the app.
While you click on a bar, the chord within the center is what’s enjoying there now. The circles round it are non-compulsory swaps, no longer random chords. The internal ring is the nearest choices, similar level or robust useful strikes like tritone subs. The outer ring is extra colour choices that also proportion notes with the middle. The violet ring is the parallel key, so should you’re on Am you may see chords from A big. Thank you!
