Harmonic Highlights

  • The structure relies heavily on diatonic ii-V-I progressions in Eb Major (Fm7-Bb7-Ebmaj7), emphasizing stable tonal centers.
  • Secondary dominants appear via Gm7-C7, functioning as a ii-V of the supertonic (Fm7) to add harmonic forward motion.
  • The inclusion of Abmaj7 (IV) creates a subdominant expansion, softening the resolution back to the tonic or the next ii-V cycle.

Improvisation Focus The Eb Major Pentatonic scale, combined with rhythmic emphasis on the “Clave” or Calypso feel, is essential for capturing the tuneโ€™s melodic simplicity.

Difficulty Rating 2/5; the predictable harmonic rhythm and lack of complex modulations make it an ideal vehicle for mastering basic ii-V-I vocabulary.
