33.21Level 9 — pivot sonority

A pivot is something that can belong meaningfully to more than one harmonic environment.

Traditionally that might be a diatonic chord shared by two keys.

In modern harmony it can also be:

  • common-tone voicing
  • slash chord
  • pedal structure
  • ambiguous upper structure

It acts as a bridge.
