Listening (Cage, John - Music of Changes (1951)

Music of Change is a composition that is played by somewhat randomly playing keys on the piano. There is not notation to this piece, however I do consider this music. I only feel this way because there is a musical instrument involved in the composition. Also there is a dynamic contrast and articulation. While Cage was the first person to think of this idea I feel that anyone could do this. This is why I consider his music more of an idea than a musical composition. Within the piece there are changes from a high register to a low one. This is a musical device that can give the piece its small musical element. Otherwise I feel this is a collection of notes.
