Harmonic Highlights:

  • Frequent use of secondary dominants (G7 to Cm, C7 to Fm7) creates strong resolutions and forward motion.
  • A ii-V-I progression to the subdominant (Bbm7-Eb7-Ab) temporarily tonicizes the IV chord, adding harmonic color.
  • The piece relies on clear diatonic harmony with interspersed standard ii-V-I progressions in Eb major.

Improvisation Focus: Applying Mixolydian modes over secondary dominant chords.

Difficulty Rating: 3 (Intermediate). Requires navigating several secondary dominants and a ii-V-I progression tonicizing the subdominant within a clear major key.
