. . . Music
Walk . . . [does not use] chance operations.
The indeterminacy in the case of Music Walk is such that I cannot
predict at all what will happen until it is performed. Chance operations
are not necessary when the actions that are made are unknowing. Music
Walk consists of nine sheets of paper having points and one without
any. A smaller transparent plastic rectangle having five widely spaced
parallel lines is placed over this in any position, bringing some of the
points out of potentiality into activity. The lines are ambiguous, referring
to five different categories of sound in any order. Additional small plastic
squares are provided having five non-parallel lines, which may or may not
be used to make further determinations regarding the nature of the sounds
to be produced. Playing positions are several: at the keyboard, at the
back of the piano, at a radio. One moves at any time from one to another
of these positions changing thereby the reference of the points to the
parallel lines.
