Harmonic Highlights

  • Frequent use of sequential ii-V-I resolutions, specifically alternating between Eb Major (Fm7-Bb7-Ebmaj7) and Ab Major (Bbm7-Eb7-Abmaj7).
  • Secondary dominant chords, such as C7 and F7, provide chromatic tension and strengthen the tonicization of the succeeding ii-7 chords.
  • Integration of the “backdoor” dominant (Db7) provides a sophisticated subdominant minor flavor when resolving toward the tonic or mediant.
  • The progression demonstrates functional fluctuation between the F minor home key and its closely related major centers.

Improvisation Focus Voice-leading through sequential ii-V-I cells.

Difficulty Rating 3/5 - While the ballad tempo is forgiving, the frequent modulations and shifting tonal centers require a solid grasp of guide-tone navigation.
