And other third movement took the remaining one minute and forty seconds.
This piece was first performed by on piano by David Tudor on August 29, 1952 at Woodstock, New York. Although the piece was composed for any instrument or combination of any group of instruments.
Tudor closed the lid of the piano to indicate the start of the movement. He opened the lid to mark the end of the movement. And he did that for the three movements. He timed the piece by counting the notes mentally and turned the pages of the sheet music accordingly.

Experiments showed that when you reach for a cup, you hand moves before your brain is aware. When the brain catches up, it then comes up with the reason as to why it “decided” to move the hand.

And the subject will not believe that the decision was influenced by anything else beside self.
