Keep time to music: also Bonobos stay on beat!



Some animals, like humans, can sense and respond to a musical beat, a finding that has implications for understanding how the skill evolved.
A study of bonobos (Species P. paniscus), closely related to chimpanzees, shows they have an innate ability to match tempo and synchronise a beat with human experimenters. Bonobos are very attuned to sound. They hear above our range of hearing.


For the study, researchers designed a highly resonate, bonobo-friendly drum able to withstand 500 pounds of jumping pressure, chewing, and other ape-like behaviours.
Scientists suspect that the musical and rhythmic abilities of humans evolved to strengthen social bonds, "so, one might think that a common ancestor to humans and the bonobo would have some of these capabilities," said Patricia Gray a biomusic program director at University of North Carolina in Greensboro.
Working with a group of language-competent bonobos at the Great Ape of Trust of Iowa, several whom have recorded with Peter Gabriel and Paul McCartney, and compose melodies using synthesizers, and in collaboration with renowned scientist, Dr. Savage-Rumbaugh, the research focuses on both empirical and theoretical inquiries in music cognition and perception, origins of culture, and theory of mind.
Experimenters beat a drum at a tempo favored by bonobos roughly 280 beats per minute, or the cadence that humans speak syllables.
