Harmonic Highlights
- Prominent use of minor ii-V-i progressions (F#m7b5-B7b9-Em7), establishing the E minor tonality and featuring altered dominants.
- Frequent temporary tonicizations and modulations, exemplified by the A7b9-Dm7 sequence, shifting briefly to D minor.
- Integration of modal interchange, such as the Cmaj7 (bVImaj7) in the E minor context, providing color and harmonic variety.
- Strategic use of descending bass lines and passing diminished chords (C07/G leading to Gmaj7), creating sophisticated voice leading.
Improvisation Focus E melodic minor scale and its derivative modes (e.g., altered scale for dominant 7b9 chords).
Difficulty Rating 4 (Advanced Intermediate) - The piece requires navigating complex minor ii-V-i progressions, multiple temporary modulations, and varied harmonic colors.
