Harmonic Highlights:
- Prominent
ivm(maj7)(Bbm/maj7) andbIIIm(maj7)(Abm/maj7) chords establish a distinctive minor-major 7 sound, often in descending motion. - Features a clear
ii-V-Itonicization of Gb Major (Abm7-Db7-Gbmaj7), a Neapolitan relationship to F minor. - Utilizes sequential altered dominants (
C7#5#9toF7#5) creating strong harmonic tension before returning to theivm(maj7). - Includes a
iiø7-V7altto Eb minor (Fm7b5-Bb7#5), introducing another temporary, remote key center.
Improvisation Focus: Melodic minor scale applications, particularly over minor(maj7) chords and altered dominants.
Difficulty Rating: 5 (Advanced) - Frequent modulations, altered dominants, and non-functional minor-major 7 chords demand high harmonic sophistication.
