Sound and Graphics

Abstract

Turing provides predefined subprograms for creating simple sounds and images. These subprograms provide the basis for entertainment, simple programming exercises, and effective ways of analyzing complex data. The material about sound in this chapter demonstrates a close relationship between two seemingly unrelated objects — a computer program and a musical form. This relationship is not coincidental. Similar structures, or patterns, occur in many different areas. Repetition, for instance, occurs in wallpaper as repeated instances of a design, in music as repeated passages, and in programming as loops.
