My thesis focuses on the intersection between music (μουσική) and law (νόμος) in 7th to 5th centuries B.C. Greek poetry. Through an analysis of legible musical notation in the surviving text, notably the rhythmic patterns of choral lyric, I aim to chart the inception and evolution of musical forms of Greek choral lyric through to the end of the fifth century. This evidence brings a new perspective to how we can hear choral lyric, as well as shed new light on the ancient aesthetic commentary that is closely tied to philosophy, pedagogy, and performance in the classical and archaic periods.
