Theme music refers to a specific piece of music that is associated with a particular show, movie, or character. It often plays during the opening or closing credits and helps to set the tone for the audience. For example, the iconic Star Wars theme by John Williams is instantly recognizable and evokes a sense of adventure and excitement. In addition to films and television, theme music can also be found in video games and sports events. It serves to create a memorable identity for the media it represents, enhancing the overall experience for viewers and listeners. A well-composed theme can become a cultural touchstone, like the Friends theme song, which many people can sing along to.
