Guido d’Arezzo

Guido d'ArezzoAlso known as

  • Fra Guittone
  • Guido Abetinus
  • Guido of Arezzo
  • Guy of Arezzo


Reformer of musical notation. Educated by the Benedictines at Paris, France he became a monk there, moving later to the monastery of Pomposa, near Ferrara, Italy, and thence to Arezzo, Italy where he probably died as prior of the neighboring monastery of Santa Croce. Called to Rome c.1022 by Pope Benedict VIII to explain his new teaching method of staff notation, he was later invited by Pope John XIX to instruct the clergy there, but the unfavorable climate prevented his acceptance. A transcription of the Antiphonarium from sign to staff notation was his text-book of the system, since called Guidonian, though his employment and improvement of the four-lined stave must not be confounded with the invention of melodic recording. His Micrologus and Epistola were written at Pomposa.
