Written around 1300 and widely distributed in the 14th and 15th centuries, the commentary on the 50 problems in this section develops an innovative discourse on the perception of singing and instrumental music and their effects. Divided between reason and sensitivity, the commentary is dominated by a physical and psycho-physiological approach to the phenomenon of sound and its perception, which breaks with the philosophical-mathematical discourse inherited from Boethius. The basic text of the present edition is the Venice edition (1519). It has been revised in the light of a collection of manuscript sources, including the oldest.
