50-45 is an instructional piece with an accompanying audio track. The numbers in the title reference certain durations of time in minutes. “50” refers to the performance as an ideal concept removed from the involvement of a performer. “45” refers to the performer’s imperfect realization of this ideal. 50-45 offers an impossible task so as to frame the conflict between one’s intentions and limitations as the core essence of their being. To perform the piece is to confront one’s self in the difference between 50 and 45.
