Synonym discussion
Sense: adjective/1
All four words describe sounds that are unpleasant to hear, but they differ in scope and register. Harsh is the most general and common — it can describe any rough, grating sound or even a texture or light. Tuneless is narrower: it says that something lacks a recognizable melody, which makes it a good fit for singing or instrumental playing that goes wrong. Discordant indicates that notes or parts clash with each other, often in a way that feels intentional or compositional rather than accidental. Cacophonous is the most formal and dramatic; it suggests a loud, jarring chaos of many sounds at once — a construction site or a room full of untuned instruments. In everyday conversation, harsh is the natural choice; in a music review, discordant or tuneless might be more precise. For example: "The choir's attempt sounded harsh and tuneless" versus "The new piece was deliberately discordant."

Etymology
Formed in English by adding the negative prefix un- (from Old English) to musical, which came into English via French from Latin musica (the art of music), itself borrowed from Greek mousikē (the art of the Muses).
