We all know the manchild Mozart of Milos Forman’s 1984 biopic Amadeus. As embodied by a manic, braying Thomas Hulce, the precocious and haunted composer supposedly loved nothing more than scandalizing, amusing, or exasperating friends and enemies alike with juvenile pranks and scatological humor. Surely a fiction, eh? Gross exaggeration, no? Undoubtedly Mozart comported himself with more dignity? Those familiar with the composer’s biography know otherwise.
We have, for example, a ridiculously dirty letter that the 21-year-old “poop-loving musical genius” wrote to his 19-year-old cousin Marianne—a missive Letters of Note prefaces with the disclaimer “if you’re easily offended, please do not read any further” (oh, but how can you resist?). This piece of correspondence is but one of many “shockingly crude letters” Mozart wrote to his family. And if these slightly insane documents don’t convince you, we offer as further evidence of Mozart’s exuberantly childish sensibility the above canon in B flat for six voices, Leck Mich Im Arsch, which translates roughly to “Kiss My Ass.”
One of three naughty canons composed in 1782 with lyrics like “Good night, sleep tight, / And stick your ass to your mouth,” this piece was discovered in 1991 at Harvard University. Harvard librarian Michael Ochs, with a clear penchant for understatement, said at the time: “These are minor works. They’re not the Requiem, or ‘Don Giovanni.’ They were written for the amusement of Mozart and his friends, and they show another side of him.” The first edition of Mozart’s complete works, published in 1804, bowdlerized the texts and removed the racy humor, changing the title of Leck Mich Im Arsch to “Let us be glad!”—likely, writes Lucas Reilly at Mental Floss, “the complete opposite of what this tune means.”
Reilly also points out that Mozart’s “potty mouth” was probably not, as some have supposed, evidence of Tourette’s syndrome, but rather of an especially strong current in German humor, shared by Johannes Gutenberg, Martin Luther, and Mozart’s equally brilliant contemporary, Johann Wolfgang von Goethe. In fact, Leck Mich Im Arsch alludes to Goethe’s serious dramatic work, Götz Von Berlichingen. The chorus reads as follows in English:
Kiss my arse!
Goethe, Goethe!
Götz von Berlichingen! Second act;
You know the scene too well!
Let’s sing out now summarily:
Here is Mozart literary!
Hear two additional dirty choral pieces—Bona Nox and Difficile Lectu—at Mental Floss. Some other scatological canons thought to be Mozart’s, such as Leck mir den Arsch fein recht schön sauber (“Lick my ass right well and clean”), have since been attributed to amateur composer and physician Wenzel Trnka, yet it appears that the three featured at Mental Floss are genuine.
