Though David and Beverly Hykkonen Rajnes are part of the Handel Festival Orchestra, Handel's works are not the only ones they perform. On Saturday at the Corcoran Gallery of Art, they'll be part of a show featuring baroque composers like C.P.E. and J.S. Bach and Haydn. And, of course, Handel. The one exception to the baroque theme is a special piece by contemporary Washington composer Thomas Bramel, "Variations on a Theme by Handel," commissioned especially for the program.

The concert, presented by the Recitalists Series in conjunction with the Washington Performing Arts Society and the Washington Friends of Handel, will feature the Rajneses (he plays the violin, she the flute). Joining them will be harpsichordist Mara Bershad and cellist David Primo, who, with the Rajneses, is part of the Washington Arts Trio.

"Tom's {Bramel} style is a tad more off the wall than on," David Rajnes says. "But it's serious, very straightforward. Harmonically, it's Straussian." He thinks the new piece will add diversity to the program.

The program starts at 8 p.m. in the Frances and Armand Hammer Auditorium at the Corcoran, 17th Street and New York Avenue NW. Call 393-3600 for information.
