- The progression utilizes a chromatic descent (Dm7 - Db7 - Cm7 - F7) where the Db7 acts as a tritone substitute (subV/V), leading smoothly into a ii-V of the IV chord (Bbmaj7).
- Frequent minor ii-V cells targeting the relative minor (Em7b5 - A7b13 to Dm7) and the supertonic (Am7b5 - D7b9 to Gm7) create a sophisticated, shifting tonal center.
- The employment of the Eb7 chord serves as a backdoor dominant (bVII7), providing a classic jazz resolution back to the F major tonic.
Improvisation Focus The primary concept is navigating minor ii-V-I patterns using the Locrian #2 and Altered scales to address the frequent tonicization of non-tonic chords.
Difficulty Rating 3/5. While the ballad tempo is forgiving, the dense harmonic motion and frequent secondary dominants require a solid understanding of functional voice leading.
