γέγονε δὲ καὶ Σακάδας <ὁ> Ἀργεῖος ποιητὴς μελῶν τε καὶ ἐλεγείων μεμελοποιημένων· ὁ δ᾿ αὐτὸς καὶ αὐλητὴς (Wyttenbach: ποιητὴς codd.) ἀγαθὸς καὶ τὰ Πύθια τρὶς νενικηκὼς ἀναγέγραπται· τούτου καὶ Πίνδαρος μνημονεύει (fr. 269)· τόνων γοῦν τριῶν ὄντων κατὰ Πολύμνηστον καὶ Σακάδαν, τοῦ τε Δωρίου καὶ Φρυγίου καὶ Λυδίου, ἐν ἑκάστῳ τῶν εἰρημένων τόνων στροφὴν ποιήσαντά φασι τὸν Σακάδαν διδάξαι ᾄδειν τὸν χορὸν Δωριστὶ μὲν τὴν πρώτην, Φρυγιστὶ δὲ τὴν δευτέραν, Λυδιστὶ δὲ τὴν τρίτην· καλεῖσθαι δὲ Τριμερῆ (Τριμελῆ Xylander) τὸν νόμον τοῦτον διὰ τὴν μεταβολήν. ἐν δὲ τῇ ἐν Σικυῶνι ἀναγραφῇ τῇ περὶ τῶν ποιητῶν (F.Gr.H. 550 F 2) Κλονᾶς εὑρετὴς ἀναγέγραπται τοῦ Τριμεροῦς νόμου.
life and works1
1 ‘Plutarch’, On Music
Sacadas of Argos also was a composer of songs and of elegiacs set to music. In addition he was a fine piper and is on record as having won the Pythian contest three times.2 Pindar mentions him3: there were three tuning-systems at the time of Polymnestus and Sacadas,4 the Dorian, the Phrygian and the Lydian, and they say that Sacadas composed a strophe in each and taught his chorus to sing the first in the Dorian, the second in the Phrygian, the third in the Lydian; this nome, they say, was called the Three-part5 because of its modulation. In the record of the poets at Sicyon, however, Clonas is given as the inventor of the Three-part.
