How to practise it

In bars 9 and 10 the roots move down one fret. Make that half step the strongest move in your line. 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.
