Today, we may know confessional poetry as a set of texts that are printed in books, but in its time it was also a performance genre. This chapter demonstrates how the performance of poems—in the privacy of the poet’s study, at public poetry readings, and in the studios of recorded literature companies—shaped this genre, determined its tactics, and influenced its style. An extended comparison of Robert Lowell and Allen Ginsberg shows that breath was a key medium for confessional poets, and a study of Anne Sexton’s career—both on the page and at the podium—shows how she “breathed back” dead poems in live performance. Throughout, this chapter focuses on the feelings of embarrassment confessional poetry raised, and the uses to which poets could put such feelings. It also highlights contemporary trends in “performance” and their impact on confessional poets—e.g., Anne Sexton’s debt to the acting theories of Konstantin Stanislavsky and to Method acting as theorized by American director Lee Strasberg.
