Harmonic Highlights:
- Frequent secondary dominants (G7 as V7/vi, C7 as V7/ii) propel the progression, creating a driving cycle of I - V7/vi - V7/ii - ii - V - I.
- The
Gb07chord functions as a chromatic passing diminished (e.g., bVIIdim7 of Fm7 or tritone sub for C7), adding tension and color. - Clear ii-V-I progressions (Fm7-Bb7-Eb) are fundamental to establishing and reinforcing the tonic.
Improvisation Focus: Targeting chord tones over secondary dominants and ii-V-I progressions.
Difficulty Rating: 3 (Intermediate). The active harmonic rhythm with multiple secondary dominants and the chromatic diminished chord demands a solid grasp of functional harmony and specific scale choices.
