12/8 BOOGIE SHUFFLE RHYTHM
Remember how you counted 12 beats in each bar in BLUEBERRY HILL? Count the same TRIPLET FEEL rhythm (4 groups of three beats) and TAP out a rhythm on the 1st and 3rd beats ONLY (leave out the 2nd beat)

Notice how it ‘SHUFFLES’ along. Now find these ‘2-note’ chord shapes with your Left-hand.

Try the rhythm using the two chord shapes
NOW TRANSPOSE the chord shapes to F and G
