Diaphonia (διαφωνια, “sounding apart”), Greek name of dissonance; dissonantia is the Latin translation of the Greek diaphonia, namely in contrast to the antiphonal and paraphonal symphonies, i.e. octave, fifth, fourth, the remaining intervals of the tonal system; so also still in medieval musicology: Cuius(symphoniae) contraria est diaphonia, id est voces discrepantes vel dissonae (Isidore, III, 20); dissonantia autem et diaphonia idem sunt (Marchettus of Padua, GS III, 80b).
(translated from the German original in: Riemann, Musiklexikon, Mainz 1967, p.223)
Diaphonia refers to harmony, motivic work, formal structure, instrumental placement in space, instrumentation, and the use of live electronics.
