A contemporary variation of the biblical story of Abraham, Sarah and Hagar. Sarah, a harpist of the Jerusalem Philharmonic Orchestra is married to Abraham, its conductor.
When Hagar, a young Palestinian horn player joins the orchestra, the thin balance in their family is shaken. Harmonia uncovers the metaphoric emotional roots of the ancient conflict between the two peoples living in Jerusalem, now seeking harmony through a dramatic encounter between Western and Eastern music. Harmonia is inspired by the biblical story from the book of Genesis, giving a feminist interpretation to the story of the "mothers" and their two half-brother boys.
