As my Song Factory course at the New School comes to its conclusion, we are moving past the specifics of particular genres and eras and into larger questions about the cultural life of songs. This week we are discussing songs in movies and TV shows. The conversation deliberately will not include scores or musicals, interesting though those are; instead, we will focus only on soundtracks. We will start off by distinguishing between scores and soundtracks: scores are custom-created for the film or show, while soundtracks are compiled from existing music. They are created by different people, too; scores are written by composers, while soundtracks are selected by music supervisors.
Next, we will explore the difference between diegetic and non-diegetic music. Diegetic music is part of the characters’ reality: songs playing on a car radio or home stereo, or a musical performance taking place. Non-diegetic music, on the other hand, is not part of the characters’ reality, it exists “outside” it. Nearly all film scores are non-diegetic, but soundtrack songs can work both ways.
