Harmonic Highlights:
- Employs
iii7 - V7/iii(Em7 - B7b9) for temporary tonicization of the mediant minor, a common Jobim harmonic device. - Features a strong
ii-V-iprogression in the relative minor (Bm7b5 - E7b9 - Am7), creating a distinct minor key section. - Incorporates unexpected chromaticism with the descending
Abm7 - Gm7sequence, adding sophisticated harmonic color and tension.
Improvisation Focus: Mastery of chord-scale relationships for ii-V-I progressions and secondary dominants, including altered dominant scales.
Difficulty Rating: 4 (Advanced Intermediate). The frequent harmonic shifts, minor ii-V-i’s, and chromatic passing chords require a solid grasp of jazz harmony.
