Anna Eberhart, the keyboardist whose insane performance caused her band's video to go viral, wants to take her enthusiasm to the Happiest Place on Earth.

The 17-year-old who plays for the Boston Crusaders Drum and Bugle Corps tells TMZ ... she's hoping if anything comes out of the clip -- which has reached over 3 million views this past weekend -- she's crossing her fingers for a role as a Disney princess ... specifically, Rapunzel.

Check out the vid, Anna explains why she was mean-mugging so hard and it's a classic. Seriously. Like ... a literary classic.
