Composers write and direct original music used to produce various types of media entertainment. They help to tell a story in a film, television show, play, or video game. Soundtracks that are created need to suit the project and convey the appropriate mood and tone. Composers create and arrange musical scores for anything that requires a soundtrack. The scores written need to be technically correct in order to create flawless performances by choruses, musicians or instrumental ensembles. Sound recordings produced from the score vary in style and may reflect the classical, country, folk, jazz, techno, or pop genres.
