Music and film have been inseparable since the inception of sound film. But even at a time when the phrases uttered by the heroes were written between shots, a man was sitting in the hall who played the piano. Sound technology in cinema has been developing for the second century.
Film music is meant to create an atmosphere. Each genre has its own style. Many youth groups became popular thanks to their compositions written as soundtracks for popular films. Many horror films and thrillers “stretch” our nerves even more with tense, sometimes ear-cutting music. Drum rolls often predict the appearance of a ghost or a maniac from behind a wall. Cool rock music at the end of the action movie, as it were, hints that the enemies are defeated, and the main character is the hero. But the gentle-slow motives of the melodramas make the lacrimal glands work even more intensely.
Often it is the music that becomes the main advantage of the picture. And the actors are not very good, and the script is so-so, and it feels like the director has just graduated from college, and he likes the film. Often and previously unknown collectives and singers became famous after working in a famous picture.
Every world famous director has his own musical preferences. Hearing only the title song, you can guess whose hands this creation. Take only directors like Tarantino and Kusturica. The soundtracks for their films are very unique.
Many filmmakers use dissonance between picture and sound to heighten the atmosphere. For example, Stanley Kubrick used the music of Mozart in his painting A Clockwork Orange. The classics were able to show even more sharply all the cruelty about which the film is narrated.
