A song is a musical composition, often with lyrics, that is performed by an acoustic instrument or the human voice. It typically has a structure that includes an opening section, followed by a bridge and climax, known as the chorus. Most songs also have a pre-chorus, which is usually shorter and provides the listener with a taste of what’s to come. The word song can also be used to describe music without words, such as an instrumental piece.
There are many different styles of song, including folk, opera and pop. A popular song is a type of lyrical music that is widely played in radio and television, as well as being sold in stores.
