Harmonic Language: Harmonically, Oregon favors modal frameworks, quartal intervals, open fifths, and occasional classical voice-leading. Towner’s piano work often blends impressionistic cluster voicings with folk-like modal harmonies; on guitar he applies classical technique, alternate tunings, and rhythmic arpeggios to produce shimmering harmonic beds.

The album represents a definitive shift in the landscape of jazz fusion, moving away from the high-volume electric rock-fusion popularized by artists like Miles Davis or Mahavishnu Orchestra toward a purely acoustic, multi-textured approach.

A solo piano piece by Ralph Towner. This track highlights the recording’s warmth. The piano tone is full-bodied and resonant. It serves as a palate cleanser, demonstrating the group's connection to the classical tradition of Satie or Debussy.
