We have about 25 pieces represented in one or another level of specificity by drawings, designs, notations, structural patterns and scores. When we say "score" we are referring to something in a graphic medium, mostly on paper, that lets us move from mental images to stage action that can be performed. Usually it's an idea that a performer or performers could not, or would not do without the graphic interpolation. In some cases they look sloppy and incomplete, haphazard and raggedy – because they are working documents shuffled around in rehearsals, not meant for display. They contain notations designed differently for different ideas. For others to appreciate them or even see what they are we often are invited to narrate, demonstrate and illustrate. A room with a large chalkboard and lots of table tops or clean floor will have us all hovering over spread-out sheets and rolls of paper, and drawing rather precisely with chalk.
