Harmonic Highlights:
- Primary ii-I progression (Fm11 - Eb69) establishes the Eb major tonic.
- Fm11 features the 11th, adding typical post-bop chordal density over the ii chord.
- Prominent Dbmaj9 functions as a non-diatonic bVIImaj9, creating a characteristic Wayne Shorter modal interchange sound.
- Alternation of Dbmaj9 with Eb69 generates tension via chromatic root movement to the tonic.
Improvisation Focus: Navigating the non-diatonic bVIImaj9 chord (Dbmaj9) by emphasizing its specific scale (e.g., Db Lydian) in relation to the Eb major key center.
Difficulty Rating: 4 (Advanced Intermediate) - The blend of functional harmony with non-diatonic modal interchange requires a strong grasp of harmonic flexibility.
