Psychoacoustics

What’s one thing that has an outsize effect on influence and emotion but doesn’t get the respect it deserves, especially in the security space?

Music.

Fascinating episode of the Cognitive Crucible:

During this episode, US Army Sergeant Major Denver Dill discusses how music and the arts can be used as tools of influence. Our wide ranging conversation covers the role of music in military operations to the theme park experience to movies to sports.

#91 DENVER DILL ON THE ARTS AND MUSIC, Cognitive Crucible Podcast

We know that effective propaganda goes after emotions, not logic. Now think of any movie you’ve watched and the way that you can be compelled to feel a certain way with the right sound or chord.

Combine music with moving images and now you have a powerful tool for influence.

Don’t believe me?

In the episode, they discuss the role music can play in influence, especially on the active battlefield. As an example, they mention the use of bagpipes as a tool of intimidation. The ominous and unsettling sound of bagpipes was used to confuse and strike fear in enemy troops.

More examples where you can see music at work – in this case, to increase anxiety – are the films of Christopher Nolan (Interstellar, Inception). Here is a good write-up about the “Shepard tone” which is deployed effectively in those films.

Shepard tone, huh?

Anxiety attack at the ~:22 mark.

This is an area that needs a lot more research.

What other ways can sound and music be applied to the modern battlefield?
