Harmonic Highlights:
- The piece frequently tonicizes A minor with iiø-V7b9-i progressions (Bm7b5-E7b9-Am6), creating a secondary minor key area.
- Prominent use of the minor iiø-V7b9-i progression (F#m7b5-B7b9-Em7) firmly establishes the E minor key center.
- A distinctive progression featuring Am/maj7 leading to a ii-V-I in G major (Am7-D7-Gmaj7) momentarily shifts to the relative major, adding harmonic contrast.
- Consistent application of V7b9 altered dominants (E7b9, B7b9) adds a sophisticated, dark harmonic color to resolutions to minor tonics.
Improvisation Focus: Navigating the various applications of the Harmonic Minor scale over V7b9 chords and minor tonics.
Difficulty Rating: 4 (Advanced Intermediate). The frequent temporary tonicizations, altered dominants, and shifts between minor and relative major tonalities demand strong harmonic awareness.
