Watch the Passing Diminished 1 online guitar lesson by Frank Potenza from Jazz Harmony Handbook

This lesson introduces the use of a passing diminished chord in Bar 6 (and NOT bar 5, as I say in the video). There is a discussion of the resolution of the bass line when using the passing diminished chord and related concerns. The two-bar turnaround in this segment is F7/D7/ G7/C7, a series of dominant 7th chords and another instance of backcycling that leaps from F7 to three steps back in the cycle of 5ths (D7) and then cycles back to the tonic chord.
