So music has a fiction in that kind of film, but in most films, music is only present to fill in emotions that are lacking. Most films claim to be realistic and the use of music in them is therefore a lie. In real life we never hear music in our lives unless it’s played on the radio or television or a musician is present. But music is used then to make up for lack of tension that the director hasn’t managed to create. I have nothing against musicals—for example, I love the films of Fred Astaire and the films of Hitchcock, but those aren’t realistic films. The use of music in conventional cinema is usually used or almost always used to make up for what’s lacking in emotion because the director has not done his job properly.
