The purpose of this study was to replicate and extend previous findings on spontaneous movement and rhythmic engagement with music in infancy. Using the identical stimuli and procedures from the original study, I investigated spontaneous rhythmic movements in response to music, infant-directed speech, and contrasting rhythmic patterns in 30 Brazilian infants (ages 5, 11, and 19 months). Findings were consistent with the original study in that more spontaneous rhythmic movements were found in response to music and metrically regular stimuli than to speech. Brazilian babies, however, showed higher means for spontaneous rhythmic movement to music than those reported in the original study. Consistent with the developmental systems approach, these results suggest that culture plays a larger role in spontaneous rhythmic engagement to music and rhythmic entrainment than previously suggested.
