Built as a summer theater in 1950, this billowy, blue big-top proved even better suited to variety shows. A nonprofit venture since 1990 (proceeds fund other cultural initiatives Cape-wide), the Melody Tent has hosted the major performers of the past half-century, from jazz greats to comedians, crooners to rockers. Every seat is a winner in this grand oval, only 20 banked aisles deep. Curtains open 8pm nightly from July to early September. There's also a children's theater program Wednesday mornings at 11am; tickets are $8. Call for a schedule.
