This is my cover of the song Cups from the movie Pitch Perfect.

More info:
This piece was performed by American actress, Anna Kendrick, in the musical comedy movie Pitch Perfect. In the film, Beca (Anna Kendrick) leads a group of misfit singers to compete in music contests.

This song served as both a soundtrack and a pivotal musical moment driving the narrative. Beca’s performance of the song not only earned her a spot in the exclusive acapella group, but also catalyzed her musical journey with the ensemble.

“Will You Miss Me When I'm Gone?” was originally recorded by The Original Carter Family in 1928 and was later, in 2009, popularized by the band Lulu and the Lampshades, which incorporated the cup rhythm featured in the film. In the song, a cup is used as percussion to play an rhythmic ostinato accompanying the singing (Dobbins and Fields).
