Derived from tó epírrhēma (τό ἐπίρρημα, ‘that which is said afterwards’), i.e. the speech following a lyric part. The succession of lyrical and spoken (or rather recited) parts is referred to as an epirrhematic composition. Aeschylus frequently used this form in semi-lyrical amoibaia. In the Old Comedy, epirrhematic composition can be found in the parabasis and in the epirrhematic agon.
