In Ghostbusters, Dana Barrett plays the cello.
Dana, portrayed by Sigourney Weaver in the 1984 film, is introduced as a professional musician and concert cellist living in New York. Her cello case appears when she returns to her apartment, and her musical career helps establish her as a serious, independent character before the supernatural events begin.
Dana becomes the Ghostbusters’ first client after witnessing bizarre activity in her kitchen, including a strange apparition emerging from her refrigerator. Her apartment building at 550 Central Park West is later revealed to be the focal point of Gozer’s supernatural plan.
A common mix-up is identifying Dana as a violinist because the film includes orchestral scenes and a separate violinist character. Dana’s instrument is specifically the cello, a large bowed string instrument held between the knees while played.
