Wilson's "Pittsburgh Cycle", also often referred to as his "Century Cycle", consists of ten plays—nine of which are set in Pittsburgh's Hill District (the other being set in Chicago), an African-American neighborhood that takes on a mythic literary significance like Thomas Hardy's Wessex, William Faulkner's Yoknapatawpha County, or Irish playwright Brian Friel's Ballybeg. The plays are each set in a different decade and aim to sketch the Black experience in the 20th century and "raise consciousness through theater" and echo "the poetry in the everyday language of black America". His writing of the Black experience always featured strong female characters and sometimes included elements of the supernatural. In his book, he wrote "My mother's a very strong, principled woman. My female characters . . . come in a large part from my mother" As for the elements of the supernatural, Wilson often featured some form of superstition or old tradition in plays that came down to supernatural roots. One of his plays well known for featuring this is "The Piano Lesson". In the play, the piano is used and releases spirits of the ancestors. Wilson wanted to create such an event in the play that the audience was left to decide what was real or not. He was fascinated by the power of theater as a medium where a community at large could come together to bear witness to events and currents unfolding.
