When listening to music, humans readily perceive and move along with a periodic beat. Critically, perception of a periodic beat is commonly elicited by rhythmic stimuli with physical features arranged in a way that is not strictly periodic. Hence, beat perception must capitalize on mechanisms that transform stimulus features into a temporally recurrent format with emphasized beat periodicity. Here, I will present a line of work that aims to clarify the nature and neural basis of this transformation. In these studies, electrophysiological activity was recorded as participants listened to rhythm

The subdivision benefit refers to the positive effect of subdividing a beat on sensorimotor synchronization. We recorded electroencephalograms of musicians and non-musicians to study how they listened or finger-tapped to a beat, subdivided into four distinct subdivisions. Musicians showed more consistent tapping responses than non-musicians, and enhanced neural entrainment during the tapping task than in the listening task. In both groups, there was a neural enhancement of the beat frequency and its first harmonic (related to duplets) after listening to the four subdivisions. Furthermore, non-

The Georgia Tech Brain Music Lab is a community gathered around a unique facility combining EEG and other physiological measurement techniques with new music technologies. Their mission is to engage in research and creative practice that brings health and well-being. This talk will present an overview of the activities at the Brain Music Lab, including sonification of physiological signals, acoustic design for health and well-being, therapeutic applications of musical stimulation, and brain-body music performance.
