This is the first critical edition of all six books of Augustine’s
De musica. Originally meant as part of a series of treatises on the liberal arts, it is especially important because of its presentation of metrics. Book six offers a theological discussion of perception based on the concept of
numerus ("rhythm"). Thus,
De musica is a fascinating document of Augustine’s intellectual development from secular learning to Christian philosophy.
