Harmonic Highlights:
- Frequent use of secondary dominants (G7 as V/ii, C7 as V/V, D7 as V/vi, Bb7 as V/IV) to create strong forward motion towards various scale degrees.
- A sophisticated chain of dominant chords (D7-G7-Bb7) preceding the IV chord (Ebmaj7), showcasing a complex circle of fifths progression.
- Inclusion of an explicitly altered dominant (F7#5) for added tension and color, alongside a passing diminished chord (E07) for chromatic voice leading into the V7.
Improvisation Focus: Altered Scale application over dominant chords.
Difficulty Rating: 3 (Intermediate) - The standard employs common jazz harmonic devices like ii-V-I and secondary dominants but introduces altered dominants and complex dominant chains requiring focused melodic navigation.
