Here are some examples of how cacophony can be used:
* Music: A piece of music with dissonant chords and clashing rhythms.
* Literature: A description of a bustling city with honking cars, shouting people, and loud construction.
* Everyday life: The noise of a crowded marketplace, a busy street, or a construction site.
In essence, cacophony is the opposite of harmony. It's a chaotic and unpleasant combination of sounds that can be both overwhelming and disturbing.
