Harmonic Highlights

  • The progression utilizes a classic I - ii/IV - V7/IV - IV movement (Ebmaj7 - Bbm7 - Eb7 - Abmaj7), effectively tonicizing the subdominant via a secondary ii-V.
  • Frequent secondary dominants (F7, C7) and their related ii-minors create a chain of cyclic ii-V sequences that navigate through the circle of fifths back to the tonic.
  • A minor ii-V-i (Am7b5 - D7b9 - Gm7) provides a temporary shift to the relative mediant (iii), requiring an understanding of minor functional harmony within a major key context.
  • The Db7 chord functions as a “backdoor” dominant (bVII7), a common non-diatonic substitution that resolves upward to the Ebmaj7 tonic.

Improvisation Focus Mastering functional voice leading through secondary ii-V-I sequences and utilizing the Bb Mixolydian/Eb Major scales to bridge shifting tonal centers.

Difficulty Rating 3/5. While the key center is stable, the rapid succession of secondary dominants and the minor ii-V in the bridge require intermediate-level harmonic navigation.
