Note 146 — Chapter XXIX · LYRIC POETRY. — THE SEVEN WISE MEN.
Reading edition
The difference between Νόμος and Μέλος appears in Plutarch, De Musicâ, p. 1132—Καὶ τὸν Τέρπανδρον, κιθαρῳδικῶν ποιητὴν ὄντα νόμων, κατὰ νόμον ἕκαστον τοῖς ἔπεσι τοῖς ἑαυτοῦ καὶ τοῖς Ὁμήρου μέλη περιτιθέντα, ᾅδειν ἐν τοῖς ἀγῶσι· ἀποφῆναι δὲ τοῦτον λέγει ὀνόματα πρῶτον τοῖς κιθαρῳδικοῖς νόμοις.
The nomes were not many in number; they went by special names; and there was a disagreement of opinion as to the persons who had composed them (Plutarch, Music. p. 1133). They were monodic, not choric,—intended to be sung by one person (Aristot. Problem. xix, 15). Herodot. i, 23, about Arion and the Nomus Orthius.
