Harmonic Highlights

  • Prominent use of secondary dominants, such as E7 (V7/Am) anticipating the ii chord, creating harmonic tension and forward motion.
  • Clear temporary modulation to the relative minor, Em, through the F#m7b5-B7-Em7 ii-V-i progression.
  • Significant modulation to the subdominant, C major, via the Dm7-G7-Cmaj7 ii-V-I progression, expanding the harmonic palette beyond G major.
  • Inclusion of non-diatonic dominants like C7 (bVII7) which often leads to unexpected resolutions or serves as a coloristic device.

Improvisation Focus Navigating temporary key centers and secondary dominants with precise chord-scale application and guide tone targeting.

Difficulty Rating 4 (Advanced) - The frequent modulations and secondary dominants demand precise harmonic awareness and advanced melodic navigation.
