Arystoksenos z Tarentu, Elementy rymtu

Aristoxenus's "Elements of Rhythm" stands as the earliest extant scientific treatise on rhythm, with only the second book enduring to our present day, albeit in an incomplete state. Demonstrating his allegiance to Aristotle, Aristoxenus employs Aristotelian concepts and investigative methods throughout his work. Notably, he introduces a conceptual division between the substance of rhythm (rhythmizomenon) and its rhythmic structure (rhythmos). Drawing parallels to Aristotle's temporal theory, Aristoxenus goes further by proposing a novel concept—the "protos chronos," denoting the smallest unit of time. This nuanced exploration not only enriches our understanding of rhythm but also exemplifies Aristoxenus' adept application of Aristotelian principles in advancing the discourse on musical theory.
