The wistful scene, released on Yahoo Movies, shows the pop-country star teaching Jeff Bridges’s character how to play the piano in a memory. Swift, who plays Rosemary, sings softly as he recalls her sad fate as the previous Receiver of Memory.
Bridges complimented Swift's acting chops at last month's Comic-Con.
"Taylor was terrific," he said. "Our scenes we had together – a lot of the scenes were at the piano, so both being lovers of music, we talked a lot of music and got to pick a little bit betweens set-ups."
Watch Swift below, and catch her on the big screen when The Giver arrives in theaters Aug. 15.
