Harmonic Highlights
- Prominent tonicization of the subdominant (Ab major) via its clear Bbm7-Eb7-Abmaj7 ii-V-I progression.
- Frequent use of secondary dominants and altered dominants (e.g., C7, C7b9, C7#5) to build tension and drive harmonic motion.
- Creative harmonic shifts exemplified by the iiø-V of F minor (Gm7b5-C7b9) redirecting to a V7/Bb (F7) before the home key’s ii-V.
Improvisation Focus Applying melodic minor modes over altered dominant chords.
Difficulty Rating 4 - The frequent use of altered dominants, transient modulations, and varied ii-V progressions requires a sophisticated harmonic understanding.
