Harmonic Highlights:
- Employs frequent ii-V-I progressions in Eb major, firmly establishing the tonic.
- Extensive use of secondary dominants (e.g., F7 to Bb, C7 to Fm) creates harmonic movement and temporary tonicizations.
- The G7b13 functions as an altered secondary dominant (V7/vi), introducing sophisticated tension and color.
- The Am7b5 chord, non-diatonic to Eb major, acts as a iiø7, hinting at momentary minor tonality or a functional substitution.
Improvisation Focus: Navigating ii-V-I progressions and secondary dominants, utilizing appropriate modal and altered scales.
Difficulty Rating: 4 (Advanced Intermediate). The standard demands navigating numerous secondary dominants, an altered dominant, and non-diatonic iiø7 chords, requiring precise scale application beyond simple diatonic improvisation.
