NYSTCE Music (165) Practice Exam

This question tests an understanding of early medieval polyphony in sacred music. The form described is organum, the first serious step beyond chant where additional voices sing in parallel with the original melody. In its simplest early version, a chant carried by one voice formed the foundation, and another voice moved in parallel, often at a fixed interval such as a fourth or a fifth, creating a thick, consonant texture. This parallel motion in service of liturgical chanting is what defines organum.

Motet later expands on polyphony with more independent lines and varied texts, not restricted to parallel motion. A cadenza is a virtuosic solo flourish within a larger piece, not a polyphonic technique. Baroque music refers to a broader historical period and its styles, rather than a specific early form of polyphony.
