Almost without exception, films have some kind of musical score. Even in the days of “silent” films, a score accompanied the film, played on a “Mighty Wurlitzer” pipe organ or even by an orchestra. Sometimes, a score was written; Charlie Chaplin even wrote his own scores for his films. Often, the score was simply a set of cue sheets; most organists improvised almost the entire film.
The techniques of music recording and editing are quite different from the techniques used in postproduction, but for the score, these worlds collide. The person most responsible for bridging this gap is the postproduction music editor.
