The phone number for concert schedule information at Fort Dupont Park was incorrect in yesterday's editions. The correct number is 426-7723.

The sun sets majestically in a cloudless sky. Children run up and down the Jefferson Memorial steps, screaming and laughing as they make fast friendships for a quick game of tag. Against the backdrop of Tidal Basin and Washington Monument, tourist meets native and the music begins.

Since 1838, when the Marine Band first performed at the Capitol, free outdoor concerts have been soothing the scorching heat of Washington summers and providing some first-class entertainment. In addition to guest vocalists and conductors with the military band performances, there are jazz, soul, rock, country and western bands.

For people-watchers, the crowd is top-notch. The best view is from a paddleboat in the Tidal Basin. They come young and old, in suits and ties, in dresses and blue jeans. There are as many tourists as natives. Bicycles are as abundant as baby strollers, jogging dates as common as family outings. Seasoned concert-goers come prepared with folding chairs, pillows, sweaters for the inevitable night breeze, insect repellant.

Betty Hadaway of Frederick remembers attending armed-forces concerts as a kid. Now she's back as a regular even though the planes en route to and from National Airport "bother me a bit."

Bikers Sally Russell and Bill Steele have ritualized their concert-going. They pedal in from Southwest and picnic with a sandwich and beer in a garden next to the Jefferson Memorial before the band starts playing.

But the military concerts aren't the only shows in town. Fort Dupont opens its summer jazz concert series Friday and Saturday with McCoy Tyner and Lon Moshe Quintet. Carter Barron Amphitheater will sponsor National Symphony concerts and a Jazz Nexus festival.

The music sung by and about the original canal builders and workers is the theme of the Concerts on the Canal. The Sunday-afternoon series will also feature jazz, blues and traditional folk music from around the world. As with all outdoor events, the concerts are canceled in case of rain.
