Harmonic Highlights

  • The melancholic ‘ivm6’ (Ebm6) functions as a chromatic passing chord between the IVmaj7 and V7, leading back to the tonic.
  • A prominent ii-V-I progression to the subdominant (Fm7-Bb7-Ebmaj7) extends the IV chord area.
  • Chromatic diminished chords (Db07, B07) create tension, acting as passing chords or vii07/ii before the ii minor chord.
  • Secondary dominants like A7#5 (V7/iii) introduce altered tensions, hinting at temporary modulations or richer dominant colorations.

Improvisation Focus: Navigating ii-V-I changes using melodic minor and altered dominant scales.

Difficulty Rating: 4 (Advanced Intermediate). The frequent use of parallel minor subdominants, chromatic diminished chords, and altered secondary dominants requires sophisticated harmonic understanding and scale application.
