Symphonia(i) (Lat., from Gk. sumphōnia: ‘an agreement of sounds’, ‘concord’, ‘harmony’)
Extract
In late Greek and medieval theory, consonance, as opposed to diaphonia or dissonance. The word symphonos also sometimes meant a unison as distinct from antiphonos, an octave, and paraphonos, a 4th or 5th.
