Harmonic Highlights:
- The iconic opening employs a striking chromatic alteration of the tonic (F, Faug, F6, Faug, Fmaj7), creating a lush, yearning quality.
- The Ab7 chord (bII7) functions as a chromatic dominant, exhibiting an unusual resolution to Am7, adding a sophisticated harmonic twist.
- Utilizes the bVII7 chord (Bb7) as a “backdoor dominant,” effectively leading to the tonic Fmaj7, a common and effective jazz idiom.
- Employs secondary dominants and deceptive resolutions, such as D7 moving directly to Fmaj7, which enhances harmonic surprise and flow.
Improvisation Focus: Targeting chord tones and guide tones, especially when navigating the song’s numerous chromatic alterations and deceptive cadences.
Difficulty Rating: 4 (Advanced Intermediate). The frequent use of chromatic alterations, deceptive resolutions, and a complex harmonic rhythm requires careful navigation beyond basic diatonic understanding.
