Questions concerning music occupy an important place in Plato's works. The
objective of the present analysis is to show that musical aesthetics develo
ped in this was are fundamentally connected with a precise idea of nature a
nd only acquire their full significance when inserted into a representation
of the world based on the concept of harmony, the principle of cohesion of
the elements and of beings.
It is the importance of this relationship between aesthetics and the image
of the world which Zarlino (1517-1590) grasped thoroughly. Although his wor
k is mainly known as a synthesis of the counterpoint rules of his era, equa
lly remarkable is his desire to insert into this representation of the worl
d the stylistic rules then in use and in this way to conciliate, in spirit
of fidelity to Plato, musical practice and speculative music.
