Connections between mathematics and music

"The concept of the film is centered around the strange connections between mathematics and music. Throughout the film, drawings representing a musical score are released into idealized landscapes that in exchange represent the conditions through which sounds travel. They alter the sounds depending on the composition of the soil, the weather conditions, the amount of light etc."
