Princess Charlotte is feeling the beat!

The royal, 7, tried her hand at directing the band during concert practice at Cardiff Castle in Wales on Saturday, conducting the orchestra to a kid-approved song. With a little assurance from her dad Prince William, as mom Kate Middleton and brother Prince George looked on, Charlotte stepped in for conductor John Quirk for "We Don't Talk About Bruno" from Disney's Encanto.

Brandishing the baton with a smile, Charlotte looked more confident with every note and even threw her head back in laughter.

The young siblings especially enjoyed spending time with the musicians. During the tour of the stage and production area, Kate shared that George, 8, is taking electric guitar lessons, while Charlotte, 7, has been practicing the piano.

On stage, the royal siblings were in awe of the sound mixing techniques. George took a turn sliding the knobs and listening through headphones. As some feedback suddenly echoed around the stage, the startled prince jumped and giggled.

George and Charlotte were a surprise addition to their parents' planned stop at Cardiff Castle Saturday, in honor of the local Platinum Jubilee celebrations happening there. The brother and sister charmed the crowd during a walkabout earlier in the day, while little brother Prince Louis, 4, was likely deemed too young to attend.
