A musical genre is a category that groups together music with similar characteristics, styles, or themes. Genres help listeners identify the type of music they enjoy and can include a wide range of styles, such as rock, jazz, classical, and hip-hop. Each genre often has its own unique instruments, rhythms, and cultural influences. Genres can also evolve over time, leading to the creation of subgenres. For example, rock music has subgenres like punk rock and alternative rock. Understanding musical genres allows people to explore different types of music and appreciate the diversity within the art form.
