Harmonic Highlights:
- Utilizes a chromatic diminished approach (C#07) to the iii chord (Dm7), functioning as a Vio7/iii.
- Features a sophisticated temporary shift to the subdominant area with Bb7-Eb7-Ebm7-Eb7, incorporating parallel minor and dominant functions.
- Employs an extended chain of heavily altered secondary dominants (G7#5 - C7#11 - F7#5) leading back to the tonic, a hallmark of Bebop harmony.
Improvisation Focus: Altered Scale (Superlocrian).
Difficulty Rating: 5 (Advanced). The rapid harmonic rhythm, pervasive altered dominant voicings, and frequent non-diatonic movements require advanced harmonic knowledge and execution.
