Not in agreement or harmony; creating a sense of conflict or discord.

Disharmonious → It is formed from "dis-" (meaning apart or away) and "harmonious" (from Greek "harmonios", meaning in harmony). The word "disharmonious" means lacking harmony or being in a state of discord.
Think of 'dis-' meaning apart, and 'harmonious' meaning in harmony — so disharmonious describes a state where things are not in harmony.
