"The play “Guido's Exercise and Dance” talks about music, or more precisely, about the emergence of music in the form in which we know it today. The work of Vladimir Martynov is equally important both as a work for sophisticated professionals and as an enlightening, educational canvas. The play tells the story of Guido Aretinsky, a Benedictine monk who, at the turn of the 10th-11th centuries. created sheet music and a modern music recording system."
