Harmonic Highlights

  • Employs tonic-dominant expansion via D7#5, utilizing the augmented fifth (A#) for smooth chromatic voice leading into the major third (B) of Gmaj7.
  • Features a sophisticated IV7 to iii7 transition (C7#11 to Bm7) followed by a chromatic bIII°7 (Bb°7) passing chord to bridge the gap to the ii7.
  • Incorporates a minor ii-V sequence (F#m7b5 - B7b9) targeting the relative minor (Em7), which then shifts through a secondary dominant (A7 as V/V) to return to the primary key.

Improvisation Focus Functional G Major scale logic with specific application of the C Lydian Dominant scale over the IV7 and diminished arpeggios for chromatic connectors.

Difficulty Rating 3 — While the tempo is usually a ballad, the soloist must navigate frequent non-diatonic passing chords and secondary dominants while maintaining a lyrical melodic line.
