The Introduction situates the monodies of Euripides’ late plays in the context of theatrical and musical innovation in Athens in the late fifth century. In plays produced after 415 BCE – in particular Ion, Iphigenia among the Taurians, Phoenician Women, and Orestes – Euripides departs from the model of actor’s lyric established by Aeschylus and Sophocles and followed in his own previous work. Solo song is no longer restricted to women, to royalty, or to situations that call for lamentation; nor is the soloist necessarily closely tied to the chorus. In his late plays, Euripides successively redefines monody: each song takes over a traditional Bauform of tragedy and builds upon it. Monody becomes a site of formal innovation and experimentation. At the same time, solo song facilitates the creation of an individual voice of broad emotional and expressive range.
