ExamplE6 BeBop BlueS uSing DiminiSheD anD 13 voicingS in a jazz groove
This be-bop blues progression features all the chords we have been looking at - m7 5, diminished 7 and 13 9. In bar 2 the B 9 is actually a Dm7 5 chord and in bars 3, 7 and 8 the Am7 5 is substituting for F9 (it’s an F9 without the root). Th3ere are several diminished chords - moving up in minor 3rds in bars 2, 6 and 8, and as passing chords in bars 1 (chromatically) and 4 (diatonic). Dominant 13b9
chords are moving in minor 3rds in bar 10, and are working with the m7 5 chord in the final II-V-I resolution in bar 12. This may all sound bewildering to read, but playing through the examples should clarify things nicely.
