Harmonic Highlights:
- Features an extended descending dominant cycle (
F7#11, Bb7#9, Eb7#9#11) utilizing colorful #11 and #9 alterations. - Employs a sophisticated minor tonic elaboration (
Dm, Dmaug, Dm6) with chromatic voice leading to add movement. - Includes a ii-V to Ab major (
Bbm7, Eb7) preceding the Dm tonic, creating a half-step dominant resolution or tritone substitution effect. - Exhibits a distinct parallel major tonic elaboration (
Dmaj7, Dmaj7#5, D6), providing significant harmonic contrast within the D minor key center.
Improvisation Focus: The D melodic minor scale and its derived modes (e.g., Lydian Augmented, Altered Scale) are crucial.
Difficulty Rating: 4 (Advanced) The complex altered dominant cycles, sophisticated tonic elaborations, and minor/major modality shifts demand advanced harmonic understanding.
