Harmonic Highlights:
- Features an Eb7#11 (IV7#11) as a Lydian Dominant, providing a characteristic jazz color and tension leading to the tonic.
- Employs a sequence of ii-V progressions, including a Cm7b5-F7b9 (iiø-V) leading to Bb, creating strong harmonic pull.
- Includes a temporary tonicization of the subdominant (Ebmaj7) via an Fm7-Bb7-Ebmaj7 ii-V-I progression.
- Utilizes altered dominant chords (G7b9, F7b9) to introduce tension and enhance dominant-to-tonic resolution.
Improvisation Focus: Navigating altered dominant scales (e.g., Altered, Lydian Dominant) over various V7 chords.
Difficulty Rating: 3/5. The standard use of altered dominants and common tonicizations requires an intermediate understanding of jazz harmony.
