- The progression Em7b5 - A7b9 - Dm establishes a strong, characteristic tonicization of the relative minor, Dm.
- The use of C7#5 adds a colorful, altered dominant quality, expanding the basic I-V progression in F major.
- An abrupt, brief tonicization of A major via an E7-A movement creates an unexpected harmonic twist before returning to F-related harmony.
- A clear ii-V-I progression to Bb major (Cm7, F7, Bb) introduces a modulation to the subdominant.
Improvisation Focus: Melodic flexibility to outline altered dominants and adapt to shifting key centers.
Difficulty Rating: 4 (Advanced Intermediate) - The unexpected modulations and frequent use of altered dominants require a strong command of harmonic substitutions and scale choices beyond basic diatonic playing.
