Harmonic Highlights

  • Sequential II-V Movement: The progression utilizes secondary dominants (Em7b5-A7 to Dm7b5-G7) to create a descending sequence targeting the ii-V-I cadence.
  • IV Chord Modulation: The transition from Bb7 to Eb6 functions as a classic I7-IV movement, incorporating blues-influenced harmonic shifts common in Stride-era compositions.
  • Chromatic Diminished Resolution: The use of Fยฐ7 between the dominant (F7) and the tonic (Bb6) provides smooth, stepwise voice leading for a delayed resolution.

Improvisation Focus Guide-tone targeting to navigate the frequent cycle-of-fifths dominant chains.

Difficulty Rating 3/5; navigating the rapid succession of secondary dominants and chromatic diminished chords requires more harmonic precision than basic diatonic standards.
