Beware a comet “if it resembles a flute,” Pliny the Elder warned; “it portends something unfavorable related to music.” The Roman author did not offer further particulars.

In 2009 a twenty-four-year-old policewoman in Long Branch, New Jersey, responded to complaints about an “eccentric-looking old man” peering into a house. She asked the man his name. “I’m Bob Dylan,” he said. “I’m on tour.” Taking him for a liar, she put him in the back of her car and drove him to his hotel, where others confirmed he really was the musician. “I think he named a couple of songs,” she later recalled. “But I wouldn’t have known any of the songs.”

Hip-hop producer Devo Springsteen was once asked why he had sampled Nina Simone’s 1965 recording of the song “Strange Fruit” instead of Billie Holiday’s 1939 rendition. “Because of the rawness of her voice,” he said. “There is something really black about her voice. And when you are trying to make black music, there’s not a much blacker voice than Nina Simone.”

Researchers working with the Tsimané of the Amazon found that tribe members could tell the difference between consonance and dissonance but took them to be equally pleasant, giving credence to the idea that Western preference for consonance is not biological. “The Greeks were really into ratios,” speculated the lead researcher. “It’s possible they started making music that way and we’ve been stuck with it ever since.”
