Chalk Line

The following inscription is found at the head of the score:
A Chalk Line is a device used for the creation of straight lines to aid in the construction of buildings. A length of string covered in chalk (or sometimes ink) powder is stretched across a flat surface, which is then pulled back and snapped onto the surface, leaving a straight line of the dust behind. This piece consists of three subsections entitled "Calligraphy," "Spirals," and "Afterimage" respectively.
