Harmonic Highlights

  • The progression utilizes E°7 as a #I°7 passing chord, creating a smooth chromatic bridge between the Ebmaj7 tonic and the Fm7 (ii) chord.
  • The Bb7#5 functions as a decorative altered dominant (V7alt), using the b13 tension to drive melodic resolution back to the Ebmaj7 tonic.
  • The harmony relies on repetitive ii-V-I cycles in Eb major, characteristic of the 32-bar ballad form, ensuring a strong, stable tonal center.

Improvisation Focus Eb Major Bebop scale, emphasizing the natural 7th and the chromatic E natural passing tone to navigate the #I°7 to ii transition.

Difficulty Rating 2/5; the changes are largely diatonic and follow predictable functional patterns, making it an accessible entry point for studying standard jazz voice leading.
