- The shift to Ab7 (bVI7) introduces a subdominant minor flavor, functioning as a chromatic “backdoor” coloration that provides a distinct bluesy contrast to the C major tonality.
- The progression features an extended secondary dominant chain (VI7–II7–V7), utilizing the circle of fifths (A7 to D7 to G7) to create strong directional pull back to the tonic.
- A passing diminished chord (C#dim7) is employed to bridge the I (C) and ii (Dm7) chords, facilitating smooth chromatic voice-leading in the bass and inner voices.
Improvisation Focus Chord Tone Arpeggios, specifically targeting the 3rd and 7th (guide tones) to clearly outline the shift from the diatonic major scale to the secondary dominants.
Difficulty Rating 2/5: The slow harmonic rhythm and logical, repetitive sequences make it an accessible entry point for learning how to navigate non-diatonic chords.
