In 2014 Amelia Hamrick, an undergraduate at Oklahoma Christian University, noticed musical notes written across the buttocks of one of the denizens of hell depicted in Hieronymus Bosch’s painting The Garden of Earthly Delights. She transcribed it into modern notation and made a recording she posted on her blog. “So yes,” she wrote, “this is literally the 600-year-old butt song from hell.” The post went viral.

Paul Wittgenstein, brother of Ludwig, lost his right arm in combat during the First World War. Wishing to continue playing the piano, he commissioned one-handed works from esteemed composers, including Benjamin Britten, Sergey Prokofiev, and Maurice Ravel, insisting, for some, on having exclusive lifetime performance rights.

Born on Lesbos around 700 BC, Terpander, a master of the kithara, was summoned to Sparta during a period of civil strife—an oracle had suggested bringing the “Lesbian singer” to help—and organized the city-state’s earliest civic music culture. Immensely popular there, he later returned for what was to be his last performance. While he was playing, a fig thrown by an adoring fan went directly into his mouth. Terpander choked on the fruit and died.

Hoping to encourage hostages held by FARC during Colombia’s civil war, state negotiators commissioned a local producer in 2010 to create a pop song embedded with a Morse-code message and had it broadcast repeatedly on the radio in rebel-controlled areas. After the lyrics “Listen to this message, brother,” the code sounded as a synth interlude: “Nineteen people rescued. You are next. Don’t lose hope.”
