Harmonic Highlights

  • The distinctive opening progression Bbm6 - D7/A - G6, featuring a non-diatonic bIIImin6 leading to the V7 of G major.
  • Frequent use of secondary dominants, exemplified by B7 (V7/vi) resolving to Em6.
  • Chromatic embellishments in the II-V sequence, such as the Ab7 - A7 - D7 progression, where Ab7 (bII7) functions as a chromatic precursor to A7 (II7) before the final D7 (V7).

Improvisation Focus Targeting chord tones with strong chromatic embellishment.

Difficulty Rating 4 (Advanced Intermediate). The non-diatonic chords and intricate chromatic movements, coupled with the typical brisk tempo, demand advanced harmonic understanding and technical fluency.
