A contemporary adaptation of the biblical tale of Abraham, Sarah, and Hagar, Harmonia presents a poignant metaphor for the contemporary challenges facing Israel’s sibling religions. Sarah, a harpist in the Jerusalem Philharmonic Orchestra, is married to Abraham, its charismatic conductor, and they have no children. When Hagar, a young Arab horn player, joins the orchestra, a unique friendship evolves between the two women. Hagar, feeling Sarah’s pain from not having children, offers to have a baby for Sarah. Ismail, born to Hagar and Abraham, is a wild and gifted pianist whom Sarah raises as her own. But when Ismail discovers the true identity of his mother, his world—and that of those around him—falls apart.
