With the fall play The Caucasian Chalk Circle fast approaching, students are working hard to make sure they know all their lines and blocking. But some actors have another part to work on: music. The play is narrated by a singer, played by senior Emily Ross, who is accompanied by a group of four musicians,  sophomores Anna Biggs, Nissa Rolf, and Claire Walsh, and junior Maddie Flom-Staab. The playwright of The Caucasian Chalk Circle, Bertolt Brecht, wrote lyrics as part of the script, but there is no official score. “We had Tim [Kraack, ‘05], our music director, create the music himself–it’s original music. So he put the lyrics to his own music and that’s what we sing,” Rolf said. “It’s really haunting and cool… It kind of makes the show.”
