Θράσυλλος τοίνυν περὶ τῆς ἐν ὀργάνῳ αἰσθητῆς λέγων ἁρμονίας φθόγγον φησὶν εἶναι φωνῆς ἐναρμονίου τάσιν. ἐναρμόνιος δὲ λέγεται, ἐπὰν δύνηται καὶ τοῦ ὀξέος ὀξύτερος εὑρεθῆναι καὶ τοῦ βαρέος βαρύτερος· καὶ ὁ αὐτὸς καὶ μέσος ἐστίν. ὡς εἴγε τινὰ τοιαύτην φωνὴν νοήσαιμεν ἥτις ὑπεραίρει πᾶσαν ὀξύτητα, οὐκ ἄν εἴη ἐναρμόνιος· οὐδὲ γὰρ τὸν τῆς ὑπερμεγέθους βροντῆς ψόφον ἐναρμόνιον ἐροῦμεν, ὅς γε καὶ ὀλέθριος διὰ τὴν ὑπερβολὴν πολλάκις γίνεται, ὥς τις ἔφη·
