Oliloqui Valley (F major) - Jazz Analysis & Chords

Chord Distribution Analysis

No obvious ii-V patterns detected.

Harmonic Highlights

• Employs a modal, non-functional harmonic structure primarily utilizing dominant 7th suspended chords (7sus4), which bypasses traditional V-I resolutions.
• Features a prominent whole-step downward shift (F7sus to Eb7sus), creating a “planing” effect characteristic of 1960s post-bop.
• The 7sus voicings function as “soft” dominants, blending dominant and subdominant colors through quartal harmony and the avoidance of the leading tone.

Improvisation Focus Mixolydian mode (F and Eb), emphasizing the 4th and 9th to maintain the open, suspended quality of the harmony.

Difficulty Rating 3/5; although the harmonic rhythm is slow, the absence of functional cadences requires the soloist to create melodic tension and narrative shape without relying on standard resolutions.
