Ever since the start of my movie soundtrack class, I've done some thinking about the challenges a composer must face when trying to compose the soundtrack for a film. My professor explained to the class how composers are given a short amount of time to create the soundtrack after the film is complete. I've heard some incredible soundtracks in my life and it occurred to me that most movies are composed of either instrumental music or vocal music.
This made me wonder: how does a composer decide in such a short amount of time whether he or she wants to create a soundtrack based on instrumental music or on vocal music? Do composers usually stick to either one kind or the other? I imagine they do — in my mind I think of movies as either being made up of purely instrumental sounds or music with lyrics. What makes a film, then, or a specific scene, worthy of instrumental music or what makes one worthy of vocal music? Is vocal music more modern? No, it doesn't seem to be that way. Many modern movies use instrumental music. Is instrumental music used in films where the director wants to reach his or her audience through their emotions without the possibility of them listening too closely to the words? I'm not sure, but I sure would love to understand more about the process.
On another note, I've also been wondering when a scene in a film, or a film as a whole, merits an original song or score. Why is it that some films simply use music that's already been recorded and produced when others get music specially recorded for the film? Does it depend on the genre of the film? Is it the director who wants a new recording to be used at the climax in order to convey the exact emotion he or she wants? Or is it the composer who decides based on the amount of time he or she has, his or her ability and his or her interpretation of the scene?
So many questions. I hope to be able to learn more about the process and understand why films are made up of different scores, instrumental or vocal; original or not.
