How to practise

Use dominant 7th chords for a bluesy feel, or plain major chords for a simpler sound. The last bar (V) is the turnaround that leads back to the start.

Play one chord per bar at 60 BPM with a simple down-strum on each beat.
Raise the tempo by 5 BPM once you can play eight rounds without a mistake.
Change the strumming pattern: down, down-up, up-down-up.
