Master Class is a 1995 play by American playwright Terrence McNally, presented as a fictional master class by opera singer Maria Callas near the end of her life, in the 1970s. As such, the play features incidental vocal music by Giuseppe Verdi, Giacomo Puccini, and Vincenzo Bellini. Alternately dismayed and impressed by the students who parade before her, she retreats into recollections about the glories of her own life and career. Included in her musings are her younger years as an ugly duckling, her fierce hatred of her rivals, the unforgiving press that savaged her early performances, her triumphs at La Scala, and her relationship with Aristotle Onassis. It culminates in a monologue about sacrifice taken in the name of art. In the leading role of Maria Callas the famous greek artist Maria Nafpliotou. Staged by Odysseas Papaspiliopoulos.
