Johannes de Grocheio (jan 1, 1255 – jan 1, 1320)

Description:

was a Parisian musical theorist of the early fourteenth century. A Master of Arts, he is the author of the treatise Ars musicae ("The art of music") (c. 1300), an attempt to describe the music of his time as it was practiced in and around Paris.

Grocheio describes a new genre that will become very important: the motet.
a. Motets had a texted duplum, which is what the word “mot” (French for
“word”) implies.
b. Early motets relate to and are connected with clausula.
c. Different parts had different texts, which we describe as “polytextual.”
