Published in 2019 at "Psychological Research"

DOI: 10.1007/s00426-019-01208-z

Abstract: Humans spontaneously synchronize their movements with external auditory rhythms such as a metronome or music. Although such synchronization preferentially occurs toward a simple 1:1 movement–sound frequency ratio, the parameters facilitating spontaneous synchronization to more complex… read more here.
