One-minute changes: switch between two chords as many times as you can, cleanly. Count every switch — a few minutes a day beats an hour once a week.

Classic pairs: A–D D–E A–E Em–G C–G G–D Am–C Am–Em C–F Dm–G F–G G–Em

A 3-beat count-in, then the clock runs. Tapping is optional (Space, or tap the screen with a free finger) — you can also just count out loud and type the number at the end.
