Hello! Today we would like to talk about how soundtracks are used in horror movies/series! If you pay attention the most present thing that you will see in this kind of music is the ostinato.
Ostinato, (Italian: “obstinate”, )plural Ostinatos, or Ostinati, in music, short melodic phrase repeated throughout a composition, sometimes slightly varied or transposed to a different pitch. A rhythmicostinato is a short, constantly repeated rhythmic pattern.
Take a look in this example! Just appreciate this soundtrack of The Walking Dead! There is an evident ostinato through the main theme!
