Harmonic Highlights:
- Features frequent non-diatonic minor chords (e.g., Dm7, Am7, C#m7) within the Ab major key center, introducing unexpected color and harmonic tension.
- Employs clear II-V-I progressions that rapidly modulate to distant keys, such as Abm7-Bb7-Ebmaj7 and C#m7-F#7-Bmaj7, showcasing Coltrane’s characteristic modulations by major/minor thirds or tritones.
- Includes abrupt shifts like Ebm7-Ab7 (II-V to Db) resolving deceptively to Dm7, highlighting Coltrane’s innovative reharmonization and altered resolutions.
Improvisation Focus: Navigating rapid modulations and non-diatonic chord changes by effectively outlining arpeggios and modes.
Difficulty Rating: 4 (Advanced). The complex modulations and frequent non-diatonic chords require a high level of harmonic sophistication and agility.
