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.
Closely related to Everything Is an Instrument, where someone creates an actual instrument based on supposedly non-musical sounds.
- An Animaniacs short had Wakko performing the Blue Danube using burps.
- 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:

- Nelson Muntz did another version in a talent contest on The Simpsons: he had a row of nerds, he wedgied them to create the notes.
- In The Adventures of Baron Munchausen, the sultan had an organ where the notes played were screams of tortured people on the other side getting poked with spikes.
- On a similar vein, History of the World Part I had the Hallelujah chorus being sung by cavemen who had their feet and stomachs hit by rocks.
- 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.
- The Muppet Show had an act called Martin Suggs and his Muppaphone. The Muppaphone was an instrument made from little fuzzy round things with faces, and they "ow"ed different notes when he clonked them with a mallet.
- A couple of handbell choir-type musical acts on The Late Show — one had glass soft drink bottles which they stuck their fingers in and popped out for the sound.
- Leroy Anderson's The Typewriter, in which the percussion section is a typewriter (including the carriage bell which rings at the end of each bar).
- Frank Zappa made a very early appearance on the Steve Allen Show, playing a bicycle
- The Vegetable Orchestra plays music with instruments made of fresh vegetables and get quite creative with their instruments. At the end of their performances they take their instruments and make soup out of them.
- The Trope Namer That Mitchell and Webb Look sketch featuring the show Anything Can Be Music; which makes a song out of "a guinea-pig realizing it's about to be put down", "a boy begging not to be caned", "a horse being kicked in the testicles", "a middle class family separated in a cave system", and a prisoner saying the actual words "Anything Can Be Music"

- John Cage believed this wholeheartedly, and built a career around it. 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.
