Harmonic Highlights:

  • Frequent use of secondary dominants (G7 as V/ii, D7 as V/ii) and V7/IV (F7) to add tension and motion.
  • Chromatic passing diminished chords (B07) effectively connect diatonic chords, notably between Bb (IV) and F/C (I).
  • Unique chromatic progression featuring a B9 (bVII9) chord appearing between C (V) and Bb (IV), adding a distinct, slightly bluesy flavor.

Improvisation Focus: Chord tone improvisation, emphasizing arpeggios and appropriate scale segments for each specific chord.

Difficulty Rating: 4 (Advanced Intermediate) - The blend of diatonic, secondary dominant, and unexpected chromatic passing chords requires precise harmonic navigation.
