Harmonic Highlights
- The frequent tonicization of bVI major (e.g., ii-V-I in Eb and Db) creates a rich minor key harmony often found in standards.
- A clear iiø-V-I progression (Gm7b5-C7b9-Fmaj7) establishes a temporary shift to the parallel major, resolving to F major.
- Significant modulations, notably a ii-V-I in Gb major (Abm7-Db7-Gbmaj7), introduce chromatic mediant relationships and expand the harmonic landscape far beyond the F minor tonic.
Improvisation Focus Chord-tone improvisation across transient modulations.
Difficulty Rating 4. Its rapid and extensive modulations to distant key centers, alongside frequent ii-V-I resolutions, demand a high level of harmonic awareness.
