Motion Tracking, Spatial Cognition, and Male Preoccupation with Music

Males have a particular interest in, and propensity for, tracking moving things. Music is the “moving art.” It’s largely about tracking beats—“moving objects”—as they sequence through time.
Males have a natural aptitude for spatial cognition (which, by the way, is associated with the hormone testosterone). As discussed in the section on brain lateralization, the right hemisphere of the brain is the location of both spatial cognition and the processing of harmony and pitch. This indicates the modules responsible for spatial cognition may handle harmony and pitch as “spatial” elements of sound.
