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. The play features incidental vocal music by Giuseppe Verdi, Giacomo Puccini, and Vincenzo Bellini. The play opened on Broadway in 1995, with stars Zoe Caldwell and Audra McDonald winning Tony Awards. Plot The opera diva Maria Callas, a glamorous, commanding, larger-than-life, caustic, and surprisingly funny pedagogue is holding a singing master class. 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. Production history The play originally was staged by the Philadelphia Theatre Company in March 1995, the Mark Taper Forum and the Kennedy Center. The play premiered on Broadway at the John Golden Theatre on November 15, 1995 and closed on June 29, 1997 after 598 performances and twelve previews. Directed by Leonard Foglia, the original cast featured Zoe Caldwell (as Callas), Audra McDonald (as Sharon), Karen Kay Cody, David Loud, Jay Hunter Morris, and Michael Friel. Patti LuPone (from July 1996) and Dixie Carter (from January 1997) subsequently replaced Caldwell as Callas, Matthew Walley replaced Morris and Alaine Rodin replaced McDonald later in the run. LuPone played the role in the West End production at the Queens Theatre, opening in April 1997 (previews) and Faye Dunaway played the role in the U.S. national tour in 1996. Master Class ran at the Kennedy Center from March 25, 2010 to April 18, 2010, directed by Stephen Wadsworth and starring Tyne Daly as Callas. The play was then revived on Broadway in a Manhattan Theatre Club production at the Samuel J. Friedman Theatre, running from June 14, 2011 (previews) to September 4, 2011 for 70 regular performances and 26 previews.
