About Guido of Arezzo
Guido of Arezzo was an Italian music theorist and pedagogue of High medieval music. A monk from the Order of Saint Benedict, he is regarded as the inventor—or by some, developer—of the modern staff notation that had a massive influence on the development of Western musical notation and practice. Perhaps the most significant European writer on music between Boethius and Johannes Tinctoris, Guido wrote the Micrologus, the most widely distributed medieval treatise on music, after Boethius's De institutione musica.
