The play concerns a brother and a sister who argue about whether they should sell their family piano. Boy Willie, a sharecropper from the South, wants to sell his family's ancestral piano to buy land. His Pittsburgh, Pennsylvania sister Berniece insists on keeping it. The piano has the carved faces of their great-grandfather's wife and son, who were sold in exchange for the piano during the days of enslavement. In essence, the piano serves as an embodiment of their struggles as a family and how they overcame. However, the piano is mystical in many ways owing to its history. Being seen as a symbolic embodiment of their past ancestry, a subtle, reserved fear is also a part of their feelings toward their piano.
