Mostly a Comedy Trope. Music is known for having certain traditions, especially what qualifies as a musical instrument, so sometimes it's fun to make music or play popular tunes using sounds that aren't really considered musical at all. Burps and farts are used often, as are animal noises.
In other words, sounds which aren't musical make a musical line.

- Older Than Television: Josef Pujol performed under the stage name "Le Petomane" at the Moulin Rouge in the 1890's. The name means essentially "The Farting Maniac", and that's exactly what he did. From The Other Wiki:

- The second and last Bozo on WGN-TV - did a bit called "Doctor Flamo" on The Gong Show of the pig organ/mouse organ/Muppaphone variety: Joey D'Auria held his hand over candles of vaious heights, his own screams of pain were the melody of the tune in question.

His most famous work is 4'33, which given the conditions of contemporary musical performance, usually consists of the noise made by a concert hall full of people trying to be silent while a pianist sits at a piano for 4 minutes and 33 seconds. Did your cellphone go off because you forgot to silence it before stepping into the concert hall? That's okay, it's technically part of the performance itself.
