Harmonic Highlights

  • The progression utilizes a II7#11 (F#7#11) immediately following the tonic, introducing a Lydian Dominant tension that defines the composition’s “slightly out of tune” character.
  • Frequent use of minor ii-V cells (G#m7b5 - C#7b9) functions as a temporary modulation to the relative vi (C# minor), adding harmonic depth to the primarily major tonality.
  • The Fmaj7 to Emaj7 transition employs a chromatic bIImaj7 “sideslip” resolution, providing a lush, bossa-nova-style cadence that avoids traditional dominant tension.

Improvisation Focus Lydian Dominant scale (specifically F# Lydian Dominant over the F#7#11) to highlight the #11 color.

Difficulty Rating 4/5 — The constant shifting between parallel keys and the non-functional chromaticism require advanced knowledge of melodic voice leading and chord-scale relationships.
