Harmonic Highlights

  • Starts with a I-ii-V in Eb major before executing a sudden parallel minor shift (Ebm7-Ab7) to reach the subdominant Dbmaj7.
  • Features a clear minor ii-V-i (Gm7b5-C7b9-Fm7) to establish the F minor tonal center.
  • The bridge uses a chromatic shift from Abmaj7 to Abm7-Db7, modulating to the distant key of Gb major.
  • Employs chromatic dominant movement (B7 to Bb7) as a subV/V approach to create tension leading back to the tonic.

Improvisation Focus Navigating ii-V-I progressions through rapid downward modulations by whole and half steps.

Difficulty Rating 3/5 because the frequent shifts between major and minor tonal centers require precise scale selection and advanced harmonic visualization.
