'The Acoustic Universe' by Micah Schippa at Prairie, Chicago

A vibration that propagates as an audible wave of pressure through a transmission medium such as a gas, liquid or solid (the air itself is a transmission medium) 

beginning with the eardrum, sound waves are translated into pitch, or a tonotopic map, and then shortly thereafter "speech and music probably diverge into separate processing circuits" 

Singing is strongly present in many different species.[45][46] Wide dispersal of singing behavior among very different animal species, like birds, gibbons, whales, and many others strongly suggests that singing appeared independently in different species. Currently, there are about 5400 species of animals that are known to sing. At least some singing species demonstrate the ability to learn their songs, to improvise and even to compose new melodies. 

Danger music is an experimental form of avant-garde 20th and 21st century music. It is based on the concept that some pieces of music can or will harm either the listener or the performer. Since the performances must nearly always be canceled before they can be performed, danger music can also be thought of more as a form of noise music.[clarification needed] For example, Takehisa Kosugi's composition Music for a Revolution[1] directs the performer to gouge out one of his or her eyes five years from now. Works such as this are also sometimes referred to as anti-music because they seem to rebel against the concept of music itself. 

Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition.
