The foundation of improvising: finding every chord’s root, 3rd, 5th and 7th with your eyes closed。
① Pick an example and a pattern (root-3-5-7 / 3-5-7-root / 5-root-7-3 / random / Guide Tones), then set the feel and repeats
② ▶ Demo: plays automatically — staff, numbers and keys all light up together
③ 🖐 My turn: follow the flashing cue and play it yourself — non-chord tones are greyed out and silent, so you cannot play a wrong note
