Cacophony
noun /kəˈkɒf(ə)ni/ — A harsh, discordant mixture of sounds.
Definition
A harsh, jarring mixture of sounds — discordant, unpleasant noise; the opposite of harmony or euphony.
Beyond the definition
Cacophony is sound as assault. Traffic, construction, a room of competing conversations at full volume — the experience of noise where harmony was expected. Sometimes used deliberately in music to create discomfort that makes eventual resolution more powerful.
Origin & history
From Greek kakophonia (ill-sounding), from kakos (bad) + phone (voice, sound). The opposite of euphony — the beautiful voice — cacophony is the bad voice.
