ExamplE2 DOMINANT 7b5 CHORDS in a RHYTHM CHANGES MIDDLE EIGHT
ch¡ This example uses the ords from the middle-eight bars of ‘rhythm
Rh£ythm, Ole£o, changes’; tunes based on I Got Flintstones etc. The first four bars are basic chords, but from bar 5 we add the ‘pure’ tritone substitution, where D7 moves to A 7 5; G7 moves to D 7 5, etc. As jazz developed, players were happy to use every chord as a 7 5 colour, as in bars 9-12. If you want to go further, use tritone substitution from the D7 5 and the C7 5 in bars 9 and 10 and convert them into A 9#11 and G 9#11. Then the last run will become chromatic 9#11 chords. Far out!
