Harmonic Highlights

  • Features a standard I-V-I foundation that moves into a I7-IV progression (Bb7 to Ebmaj7), a signature trope of early 20th-century popular song.
  • Employs the C#dim7 (passing diminished) to create a smooth chromatic bridge between the IV chord and the ii-V or tonic arrival.
  • Incorporates a secondary dominant (C7) acting as a V/V to strengthen the resolution to the dominant (F7) during turnaround sections.
  • Utilizes a diatonic walk-up (Bb - Cm7 - Dm7) providing linear melodic motion within the underlying Bb major tonality.

Improvisation Focus Bb Major Bebop Scale (emphasizing the transition between the major 6th and dominant 7th to highlight chord changes).

Difficulty Rating 2 (Beginner-Intermediate): The harmony is predominantly diatonic and utilizes standard functional resolutions, making it highly predictable for soloing.
