Metallica calms the monkeys

To be precise, these are tamarins, small monkeys with long white manes that live in Central and South America.

BEIJING, Sept. 2 (Xinhuanet) — Monkeys prefer heavy metal to classical music, according to researchers at the University of Wisconsin whose findings are published this week in Biology Letters.

Scientists played a selection of music to a group of cotton-top tamarin monkeys but the only tunes that got a reaction were from the heavy metal band Metallica. They were seemingly disinterested in Led Zeppelin, Miles Davis and Bach, but after the dulcet tones of Master of Puppets by Metallica was played the tamarins calmed down.

“Monkeys interpret rising and falling tones differently than humans. Oddly, their only response to several samples of human music was a calming response to the heavy-metal band Metallica,” said Professor Charles Snowdon, from the University of Wisconsin-Madison.

Rather than making them agitated or aggressive, the heavy metal tracks had a soothing effect.
