Malia Obama Makes Music Video Debut Dancing, Playing Harmonica

Malia Obama made her onscreen debut in a music video ... which is very Harvard-centric.

Malia dances and plays the harmonica in the video, "Walking on Air." The band -- New Dakotas -- is comprised of 4 members, all of whom attend Harvard.

She appears at 1:41 and again at 2:01 in the video.

The dudes in the band are seniors ... in the class if '19. Malia's a sophomore and is set to graduate in 2021.

This isn't the former First Daughter's entre into showbiz. She was a P.A. on Halle Berry's sci-fi drama "Extant." She also interned for Harvey Weinstein's company in NYC.
