The Ceremonial Band and the Herald Trumpets will take part in a ‘‘Capitol Fourth” concert on the West Lawn of the U.S. Capitol beginning at 8 p.m. and the Concert Band along with members of the pop⁄variety ensemble Downrange will join country music star Mark Wills for the National Park Service’s annual ‘‘Fourth of July Concert on the National Mall” on the grounds of the National Monument beginning at 6 p.m.

Master Sgt. Mercy Diez, a vocalist with Downrange, said the two units would each perform an hour’s worth of music and then share the stage with Wills, who has accompanied Army Band musicians before as part of the sergeant major of the Army’s and USO’s annual trip to visit deployed troops during the Christmas holiday.

‘‘This is a really fun show for us,” said Diez. ‘‘We [Downrange] haven’t done the 4th of July in a long time.” She said the group would perform the songs ‘‘Let it Rock” by Kevin Rudolph, ‘‘It’s a Man’s World,” by James Brown, and ‘‘Freedom,” by Wynnona Judd, among others.

The Army Chorus will be out of town on the Fourth, playing in the peach state with the Atlanta Symphony Orchestra in a program that includes Aaron Copeland’s ‘‘Fanfare for the Common Man,” and ‘‘A Lincoln Portrait.”

Meanwhile, the Army Herald Trumpet will be in Massachusetts playing with the Boston Pops on the city’s esplanade.

Dressed in Revolutionary War era woolen uniforms, The Old Guard’s Fife and Drum Corps will be participating in events at the National Archives beginning at 10 a.m. for a special program celebrating the signing of the Declaration of Independence.

The Fife and Drum Corps will also march in the 4th of July Parade down Constitution Avenue beginning at 11:45 a.m.

Later in the evening Fife and Drum musicians will play music to accompany the fireworks, including ‘‘Yankee Doodle Dandy,” ‘‘Marshall Lowendahl’s March,” ‘‘The Girl I Left Behind” and ‘‘Brandywine Quickstep.”

Staff Sgt. Kara Loyal, a fifer who has been with the corps for four years, said she really likes the patriotism on display the 4th of July.

Hopefully it won’t be too humid and affect her instrument. ‘‘We try to keep them dry as long as possible,” she said. ‘‘They get a funny sound when they get sticky.”

Loyal said she’s told her friends and family how the day’s events will be broadcast on television’s Public Broadcasting Service. ‘‘The TiVos will all be going to catch it,” she said.

Staff Sgt. Matthew Dewaegeneer, a broadcaster and ceremonial announcer with the Old Guard said approximately 150 Old Guard Soldiers would be participating in local Fourth of July events, including a ‘‘Salute to the Nation” ceremony on Fort Myer’s Summerall Field at noon on the 4th of July.

Old Guard Soldiers will also march in the 4th of July Day parade, including the Continental Color Guard and Old Guard Regimental Commander Col. Joseph Buche. Participation in the parade is likely to be one of the commander’s last official acts before passing the guidon to his successor.

Dewaegeneer said he always enjoys participating in 4th of July events. ‘‘You know you’re always going to have a big crowd with lots of kids,” he said.
