Richard Struass wrote some of the first movie scores with his heavy drive to create 'program music;' ironically before there were any soundtracks on movies. Indeed his scoring techniques are closely studied by the likes of John Williams and others.
Movies are usually made in committee style of functions with the majority reports winning out or the person with the most rank pulling things in their direction. I've often wondered how much control directors really have over the final cut of the movie; seems to me that the process goes something like this:
Director decides, after consulation with the arts committee and the production committee, (which committee is often just one person), which scenes require a musical backdrop and then requests the mood to be set, the style and the thickness or thiness of the music, one insturment, chamber group or Straussian dimensions to the max.
Interestingly, one of my favorite movie scores is Stanley Kubrick's '2001, A Space Odessy' which uses only music that was previously composed, a favorite technique of Kubrick. I wonder if any one has some statistics on how many times that music has been quoted in other contexts (Strauss's fanfare to Thus Spake Zarathustra) where the implications are either Mocking or serious. In other words, Kubrick wanted his audience to notice it:
- Richard Strauss, Also Sprach Zarathustra
- Johann Strauss, The Blue Danube Waltz
- György Ligeti, Atmospheres, Lux Aeterna,
and Requiem for Soprano, Mezzo-Soprano, Two Mixed Choirs and
Orchestra
- Aram Khatchaturian, Gayane Ballet Suite
