Chimps Prefer African And Indian Musical Beats

Chimpanzees prefer silence to Western classical and rock music.

WASHINGTON While preferring silence to music from the West, chimpanzees apparently like to listen to the different rhythms of music from Africa and India, according to new research published by the American Psychological Association.

"Our objective was not to find a preference for different cultures' music. We used cultural music from Africa, India and Japan to pinpoint specific acoustic properties," said study coauthor Frans de Waal, PhD, of Emory University. "Past research has focused only on Western music and has not addressed the very different acoustic features of non-Western music. While nonhuman primates have previously indicated a preference among music choices, they have consistently chosen silence over the types of music previously tested."

They also do not like Japanese music. They might hear Japanese and Western music as threatening dominance displays.

When African and Indian music was played near their large outdoor enclosures, the chimps spent significantly more time in areas where they could best hear the music. When Japanese music was played, they were more likely to be found in spots where it was more difficult or impossible to hear the music. The African and Indian music in the experiment had extreme ratios of strong to weak beats, whereas the Japanese music had regular strong beats, which is also typical of Western music.

"Chimpanzees may perceive the strong, predictable rhythmic patterns as threatening, as chimpanzee dominance displays commonly incorporate repeated rhythmic sounds such as stomping, clapping and banging objects," said de Waal.

I wonder if Bonobos respond the same way.
