Genres are categories that help classify various forms of art, literature, and entertainment based on shared characteristics. For example, in literature, genres include fiction, non-fiction, mystery, and fantasy. Each genre has its own conventions and themes, making it easier for audiences to find works that match their interests. In music, genres like rock, jazz, classical, and hip-hop group songs based on style, instrumentation, and cultural influences. Understanding genres allows creators and consumers to communicate more effectively about their preferences and helps in discovering new works that align with their tastes.
