pitch simultaneity

Noun

 * 1)  Any two or more pitches or pitch classes all of which occur simultaneously, or at the same time. It may be thought of as a more general term for any possible chord. Any chord progression or harmonic progression is then a simultaneity succession, though not all simultaneity successions are harmonic progressions and not all simultaneities are chords.
