A rude joke built to multiply
Mozart’s obscenity is only half the joke. The piece is a six-part canon: singers begin the same tune at different moments, so each new voice joins while the earlier ones continue. Instead of delivering the phrase once, the group keeps stacking it into a coordinated musical tangle.
That structure makes the canon work especially well as party music. Each singer has a relatively simple line to learn, but the overlapping entrances demand attention—and the growing chorus turns a crude sentence into a shared performance. The humor comes from the contrast between the deliberately vulgar words and the disciplined musical construction.
Counterpoint for the company
The interlocking voices are an example of counterpoint, the art of combining independent musical lines so they sound coherent together. Here, the form gives the singers a small challenge: hold your place, listen for your entrance, and keep the tune going as the others catch up. The joke is therefore not just in what the words mean, but in how many people have to sing them together.
Mozart’s canon joins musical craft to the social pleasure of friends performing something mischievous. Its punchline becomes more effective with every voice that enters.
