Projected set In music a projected set is a technique where a collection of pitches or pitch classes is extended in a texture through the emphasized simultaneous statement of the a set followed or preceded by a successive emphasized statement of each of its members. For example, a set may be stated as a simultaneity and then a series of phrases may end on notes which are the members of the set, as in the downbeat of m. 19 through measures 46 of Béla Bartók's Second String Quartet.
