This article is pretty interesting for a couple reasons- it examines the reactions of different species to music. Ultimately, the scientists involved seem to have determined that human music doesn’t have the sonic cues to be meaningful to monkeys (in this case, Cotton Top Tamarins). You can listen to some of the music that the scientists made for the monkeys, which is pretty awesome. But also awesome is this detail:
“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.”
Fuck yeah! Metallica, good for torturing terrorists and calming monkeys.
