I mean, have you ever watched a movie without sound? It helps the tempo and pace of a film. For instance, think about thriller movies. I believe that they use sound to increase one’s anxiety. Listening to noises or sounds most definitely can change the mood. Say if one was listening to a sad and slow-paced song, it could make one think of something distressing or a tragic moment in their lives previously. Sound affects our emotions or mood due to the dopamine regulation in our brain. Listening to the “Moon Graffiti” video, I had so much anxiety. When they were calling to see if someone was there was nerve-wracking to me. The whole snippet on Soundcloud was very eerie.
