Harmonic Highlights:
- The opening alternates between G minor (Gm) and G major (Gmaj7, Gm/maj7/F#), establishing an early modal ambiguity and sophisticated tonic treatment.
- Features frequent and smooth modulations, notably to Eb major (Fm6-Bb7-Ebmaj7) and Bb major (Cm7-F7-Bbmaj7) via cyclic
ii-V-Iprogressions. - Employs extended chains of dominant-oriented
ii-V-Imovements, rapidly shifting key centers before returning to G major. - Includes a prominent Abmaj7, functioning as a bVI in the temporary Eb key, adding a rich chromatic color.
Improvisation Focus: Navigating successive ii-V-I progressions across multiple key centers.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent and rapid modulations, coupled with extended ii-V-I sequences, demand a solid grasp of key center outlining and voice leading.
