Butt tattoos have been badass since the 15th Century. Hieronymus Bosch's 'The Garden of Earthly Delights' is a 3-paneled painting depicting The Garden of Eden, The Garden of Earthly Delights, and Hell. In the Hell panel, a person with sheet music written on their ass lays underneath instruments while being tortured. And we finally can hear what that music sounds like. 

Back in 2014, Amelia, a music student posted on Tumblr about discovering the butt music and arranging it as a piano melody. In the original post, she explains “I decided to transcribe it into modern notation, assuming the second line of the staff is C, as is common for chants of this era.”

Weird Medieval Guys on Twitter shared the ass track, as people have been arranging and recording their own renditions. A more biblical feeling version features Gregorian chants.

Adding the butt tattoo music to my Hell playlist for when it feels like literal hell outside during the summer.
