How to practise it

Cycle the key in 4ths with the routine panel. That is how jazz players drill ii–V–I through all twelve keys. Start at 70 BPM with the drums and chords on, and say each chord name as you reach beat one. Once it flows, switch on memory mode, then raise the tempo with the speed builder. Earn bronze for playing it through, silver at 120 BPM in quarter notes (2 notes a second), and gold at that pace from memory.
