Harmonic Highlights

  • Extended Dominant Cycle: The progression utilizes a sequential chain of secondary dominants (E7-A7-D7-G7), traversing the circle of fifths (V/vi to V/ii to V/V to V) to return to the tonic.
  • Secondary Modulation: The bridge features a brief tonicization of the dominant key (G major) via a II-V-I movement, a hallmark of early Tin Pan Alley songwriting.
  • Modal Mixture: Employs the minor subdominant (Fm6), providing a classic “sentimental” chromatic resolution (ivm6 to I) common in ballad and swing eras.

Improvisation Focus Guide tone connectivity through the extended circle of fifths dominant chain.

Difficulty Rating 2/5 (Beginner-Intermediate). The slow harmonic rhythm and predictable cycle of fifths make it an excellent vehicle for mastering secondary dominants without high-speed technical demands.
