Broadway theatre is often considered the highest professional form of theatre in the United States. Plays and musicals are staged in one of the 39 larger professional theatres with at least 500 seats, almost all in and around Times Square. Off-Broadway theatres feature productions in venues with 100–500 seats. Lincoln Center for the Performing Arts, anchoring Lincoln Square on the Upper West Side of Manhattan, is home to 12 influential arts organizations, including the Metropolitan Opera, New York City Opera, New York Philharmonic, and New York City Ballet, as well as the Vivian Beaumont Theater, the Juilliard School, Jazz at Lincoln Center, and Alice Tully Hall. Performance artists displaying diverse skills are ubiquitous on the streets of Manhattan.
