Iconic sounds connected with the genre

There are different types of sound and music used in thriller horror movies. Sometimes the movies starts with a loud noise to alert the audience, for example this could be a loud door slamming or a phone ringing, just like in Scream 4. Or in other movies, it starts with no sound or music and then when there's drama, there's a loud sound or music playing to show that the character is in danger. This gives the audience an enigma when something dramatic happens, like in some movies they will play fast, upbeat music when the character is running to save someone. Another iconic sound is the music/sound slows down but then there's a loud sound when there's something behind them. But sometimes the music is played throughout the movie which gives the audience a feeling that the movie isn't scary, but then something sudden happens which spooks them. For example Psycho is very famous for the intense music that made one scene iconic.
