Harmonic Highlights:

  • Frequent chromatic dominant approaches to the tonic, notably Eb7 (bVII7) and Db7 (bV7) resolving directly to Fmaj7, providing distinctive color.
  • Use of altered dominant F7#5 to Bbmaj7 (V7#5 to IV), adding tension and a sophisticated sound to a standard resolution.
  • Incorporation of a descending chromatic diminished chord (Abø7 after Am7) leading into the ii-V of Bb (Cm7-F7), creating smooth voice leading and harmonic interest.

Improvisation Focus: Altered Scales and Chromaticism, essential for navigating the numerous non-diatonic and altered dominant chords.

Difficulty Rating: 4 (Advanced Intermediate). The frequent use of non-functional dominants and altered extensions requires a sophisticated understanding of melodic choices beyond diatonicism.
