- The progression oscillates between C major and its relative A minor, utilizing both major and minor ii-V-I cadences to create tonal ambiguity.
- The Dm7b5-G7b9-Cmaj7 sequence employs a “borrowed” minor ii-V to resolve into a major tonic, adding a distinct melancholic color.
- Frequent use of secondary dominants, such as A7b9 and B7b9, provides chromatic tension that drives the harmony toward the IV chord (Fmaj7) and the V of A minor (E7).
- The sequence Am-Am/G-F#m7b5-B7b9 features a descending bass line and a ii-V in the key of the dominant, creating a sophisticated bridge to the E7.
Improvisation Focus Guide-tone voice leading to navigate the transition between major and minor ii-V-I sequences.
Difficulty Rating 3/5. The harmonic rhythm is predictable, but the soloist must accurately switch between different sets of alterations for the major and minor dominant chords.
