A Subject of Four Notes: William Crotch's Experiment in Motivic Saturation
Music Theory Online, 0(10).
This paper discusses the circumstances that drew William Crotch into a highly specific and systematic compositional procedure, and describes how the severe material and procedural restrictions of his *Introduction and Fugue on a Subject of Four Notes, no others being used all thro' the movement* (ca. 1830) nevertheless permit the creation of a successful musical work on both intellectual and artistic scales. The analytical focus of the article is the manner in which Crotch establishes and deploys a varied content through a coherent and developmental design despite the self-imposed limitations.
