From: J. McDermott and M. D. Hauser, “Nonhuman primates prefer slow tempos but dislike music overall,” Cognition, vol. 104, no. 3, pp. 654 – 668, 2007.
We started with an extremely crude and coarse-grained contrast between two pieces of instrumental music: a Russian lullaby played on a flute, and an excerpt of German electronic techno… We measured the average event rate of the lullaby and techno to be 65.26 and 369.23 beats per minute, respectively.
