"Composition" is the act or practice of creating a song or other piece of music. In many cultures, including Western classical music, the act of composing typically includes the creation of music notation, such as a sheet music "score," which is then performed by the composer or by other instrumental musicians or singers. Musical composition can refer to an original piece of music, either a song or an instrumental music piece, the structure of a musical piece, or the process of creating or writing a new song or piece of music. The word "song" is widely misused by people in the popular music industry to describe any musical composition, whether sung or played only by instruments. People who create new compositions are called composers in classical music. In popular music and traditional music, the creators of new songs are usually called songwriters; with songs, the person who writes new words for a song is the lyricist. Play or pay is usually non-negotiable for two main reasons: it assumes the producer paid the full composer’s fee and it allows the producer to reject the score if they feel it doesn’t fit. To keep the composer and producer on the same page, they can agree that the composer will provide part of the score and the producer can decide whether work should be continued. Prior to accepting the final score, the producer usually will retain the right to request certain changes, omissions or additions to the movie's music. In addition, the producer generally has the right to not use the composer's score in the final version of the movie provided that the composer has been fully compensated for creating and/or recording the score.
