How this composer integrated neuroscience into her music

When composer Sarah Hennies learned about a neurological theory called “motor tapes” from Oliver Sacks’ book Musicophilia, the concept stuck with her for years. The theory comes from neuroscientist Rodolfo Llinás, who posited that many of our thoughts, memories, and physical movements operate via a series of “looping tapes,” with the goal of reducing the amount of energy the brain uses while doing common, repetitive tasks.

The concept resonated with Hennies, who is also a visiting assistant professor of music at Bard College. Most of her compositions use heavy amounts of repetition, and Llinás’ theory fit with how she experienced her own memories and the evolution of her identity. Her piece “Motor Tapes” premiered in early August, performed by Ensemble Dedalus.

Hennies joins guest host and musician Dessa to talk about repetition in music, how to translate neuroscience into art, and what that pairing can reveal about our bodies and the world around us.

Universe of Art is hosted and produced by D. Peterschmidt, who also wrote the music. Our show art was illustrated by Abelle Hayford. Support for Science Friday's science and arts coverage comes from the Alfred P. Sloan Foundation.
