A short progression of ukulele chords plays, with a marker sweeping the cards. The last card stays blank — listen to the chord voiced there and name it from the buttons. Every chord sounds as its real beginner uke shape (GCEA, high‑G). You start with C, G, Am and F; each level adds one more — Dm, Em, D, A, then E7, A7, C7 and finally Gm — and the progressions grow longer.
