John Cage Ė American (1912 - 1992)

Cage wanted people to listen to silence around them with the attitude they bring to a concert

We can find rhythms in the sound of someone speaking
Or hear harmony in a power drill
 

Cage believed these could be just as musical as a symphony

Silence isnít silent
Itís filled with sound
People walking down the hall
The vibration of the HVAC units
People giggling
People shifting uncomfortably in their chairs

 

All of these can be heard as music
If you donít believe me
Try sampling it and giving it to a DJ
