Harmonic Highlights
- Prominent use of the I-vi-ii-V progression establishes clear diatonic movement in C major.
- Introduction of Fm6 (minor iv chord) provides modal mixture, borrowing from C natural minor for a darker color.
- The Am-Am/maj7-Am7 sequence over the vi chord creates a sophisticated, chromatically descending upper voice.
- The D7 (V/V) and D#ø7 combination introduces secondary dominant function and chromatic diminished tension.
Improvisation Focus Targeting chord tones and understanding dominant alterations.
Difficulty Rating 3 (Intermediate). While much of the tune is diatonic, the presence of borrowed chords, secondary dominants, and chromatic diminished chords adds significant complexity.
