German scientist Gaspar Schott’s 1657 Magia universalis naturæ et artis includes a description of “the music of donkeys”: “the trick, according to Schott, lay in using male donkeys of particular natural pitches and stimulating them to bray with the urine of a female donkey, which will induce the males to make ‘most contented’ noises that the generous might construe as a kind of music.” Schott had argued that “the excessively discordant singing” of men and animals becomes sweeter when encountered rarely.
