As Donald Trump took the oath office as the 45th President of the United States, Dartmouth native and Marine Corps Master Gunnery Sgt. Matthew Harding sat just feet away, trumpet in hand.

He’s a member of "The President's Own" United States Marine Band. Founded in 1798, the military band has performed at every Inauguration Day since 1801. It’s a responsibility Harding takes very seriously.

“It’s exciting to be part of the peaceful transition of power,” Harding said. “It’s inspiring to see the huge crowds. You’ve really become a fly on the wall of history.”

It was Harding’s fifth inaugural performance to date. He participated in former presidents George W. Bush and Barack Obama’s inaugurations. While Harding and the band also cover a national tour and other formal assemblies attended by the president, Inauguration Day is a special affair that requires careful planning.

“There’s a bit more attention to detail for inaugurations,” Harding said. “We want to make sure everything is just right.”

Growing up in Dartmouth with parents who were both music teachers, Harding’s exposure to music came at a young age. As he moved through the Dartmouth school system, he took every opportunity to be involved in music that he could. He joined the Dartmouth High marching, concert, and jazz bands – class of 1992 – and remembers the experience fondly.

“The band has always been competitive. It was successful when I was there, and I’m happy they continue to thrive,” Harding said of the high school band, which celebrated a first place win in the USBands National Championship in November.

Harding ended up in the military band by chance. After studying at the University of Rochester, he began a master’s degree program at Rice University. When he heard that a vacancy had opened up in 1998, he jumped at his chance to audition. After being accepted into the band, Harding dropped out of his master’s program.

He’s been a proud performer for the 19 years since then.

Just how long does it take to rehearse for a performance that will be seen by millions of people, including the president himself? About two weeks, according to Harding.

Rehearsals cover a new topic every day – including sheet music and technical aspects – to ensure the show goes on without a hitch. The band even pre-records a flawless rendition of its set just in case severe weather conditions interfere with a live show. However, a recording was not needed this year with the seasonal weather, Harding said.

For his part, Harding played the trumpet during the prelude ceremony, during Trump’s ceremony, and marched in the inaugural parade. He also performed at the inaugural ball and at an interfaith prayer service, and has no intention of leaving the band anytime soon.

“I’m going to stay as long as they let me,” Harding said.

He now lives in Alexandria, Virginia, but does maintain family ties in Dartmouth.
