1. Play the notes of a G7 chord as an arpeggio – G B D F
2. Precede each chord with a semitone (half step) from below – F# G, A# B, C# D, E F
3. Use any combination of the two-note groups (approach note plus chord tone) making sure, however, that you always end on a chord tone (G B D or F)
4. Be creative with your rhythms and choices of register.
