The music that accompanies film is equally as pervasive as the images that move across screen and stage. In stage productions, theater music plays on the moods of operettas like Henry Baldwin’s St. Nicholas Book of Plays and Operettas and in Arthur Penn’s Yokohama Maid: A Japanese Comic Operetta. In silent films, live music (guitarists, pianists, and live orchestras) was often paired with public projections. In the science-fiction classic Star Wars, Darth Vader’s theme music is as ominous as his character. The same goes for Jaws; composer John Williams created a suspenseful backdrop that had become synonymous with impending danger. Today, original soundtracks (OST) are often found on the top of the Billboard charts.
