Harmonic Highlights:
- The recurrent C7 (IV7) creates a blues-inflected, pre-bebop sound against the G major tonic, diverging from standard functional harmony.
- Extended II-V progressions, such as Bm7-E7-Am7-D7, demonstrate sophisticated functional harmony leading to both minor and major tonics.
- C#o7 functions as a passing diminished chord, creating strong voice leading from Cmaj7 (IV) to Gmaj7 (I), often implying a V7/ii substitution.
- Tonicization of the relative minor (Em7) via F#m7b5-B7b9 showcases a common jazz device for temporary modulation within the major key.
Improvisation Focus: Navigating II-V-I progressions effectively using chord tones and appropriate modal scales.
Difficulty Rating: 3 (Intermediate). The tune features accessible II-V-I patterns alongside characteristic jazz elements like the bluesy IV7 chord and passing diminished harmonies.
