Harmonic Highlights:
- Frequent use of altered dominants (D7#5, B7b9) adds tension and color before resolutions.
- The C7#11 (IV7#11) introduces a distinct modal interchange or Lydian Dominant color, briefly moving away from diatonicism.
- A descending chromatic diminished chord (Bb07) serves as a sophisticated passing chord, connecting Bm7 to Am7.
- Features a common ii-V-i progression to the relative minor (F#m7b5 - B7b9 - Em7) followed by a V7/ii to Am7.
Improvisation Focus: Navigating altered dominant scales and arpeggios for sophisticated voice leading.
Difficulty Rating: 4 (Advanced Intermediate) - The blend of diatonic, altered harmony, modal interchange, and passing diminished chords demands a strong harmonic understanding.
