With a book by Peter Stone ("Titanic") and music by Sherman Edwards, "1776" presents the quandaries of the Founding Fathers, who all happen to know how to sing on key.

CLASSICAL

WHEN THE 65 BELLS buried with the Marquis Yi of Zeng were cast in the fifth century B.C., they included inscriptions telling why and when they were made and, more important, information about pitch and placement in the set. So the magnificent Chinese bells on display as part of the National Gallery of Art's "The Golden Age of Chinese Archaeology" exhibit can indeed come to life. The bells are, in fact, replicas of the originals, but very high-quality replicas cast with all the expertise of modern metallurgy. The bells will be played this weekend, with music selected from a broad historical range, including some speculative works from the pre-notation era contemporaneous with the instrument.

--Philip Kennicott

At the National Gallery of Art East Building, Fourth Street and Constitution Avenue NW. Sunday at noon and 3 p.m. Free. 202-737-4215.

FILM

MYTHOLOGY, MARTIAL ARTS AND METAPHYSICS meet in the cyber-punk thriller "The Matrix," starring Keanu Reeves as the man in the machine, a computer hacker destined to save the world. Though they don't know it, humankind has literally become trapped in the web of a cabal of sentient supercomputers that have claimed the planet as their own. Laurence Fishburne, as the leader of the resistance, recruits "the chosen one," then prepares him for the formidable battle.

DANCE

JEROME ROBBINS WAS ONE OF THE MOST INFLUENTIAL American-born choreographers, but the breadth of his legacy has rarely been witnessed outside his home town of New York. A demanding taskmaster, he allowed few companies other than the New York City Ballet (where he produced most of his work) to perform his compositions. One of those few is the San Francisco Ballet, under the direction of former NYCB principal dancer Helgi Tomasson, who was among Robbins's favorite dancers. Her company opens its week-long engagement here with an evening of Robbins ballets--the menacing "Cage," the tender "In the Night," "Glass Pieces" (to music by Philip Glass) and "A Suite of Dances." On the weekend, the company performs in another vein entirely in Tomasson's new staging of the 19th-century romantic ballet "Giselle."

--Sarah Kaufman

At the Kennedy Center Opera House. Robbins program Tuesday through Thursday at 8 p.m.; "Giselle" Friday at 8 p.m., Saturday at 2 and 8 p.m. and Sunday at 2 p.m. 202-467-4600.
