The scene depicts Dame Music as she recounts to Dame Justice the torments she has undergone at the hands of certain musicians of the time: Melanippides seized, debased, and weakened her with 12 tones; Cinesias ruined her with badly composed modulations; Phrynis bent, twisted, and completely destroyed her by sounding all 12 tones on the kithara; and, most egregiously of all, Timotheus, with his shrill dissonances and sinfully high-pitched and piercing notes and whistles, crammed her with modulations just as a cabbage-head is crammed with caterpillars, depriving her of all decency with his 12 tones.
This according to “Studies in musical terminology in 5th-century literature” by Ingemar Düring, an essay included in Eranos Löfstedtianus: Opuscula philologica Einaro Löfstedt A.D. XVII kal. iul. anno MCMXLV dedicata (Uppsala : Eranos Förlag, 1945; RILM Abstracts of Music Literature, 1945-34).
