Four individuals in 19th-century attire are singing carols in front of a tall, decorated Christmas tree inside a building with a dark tiled floor. The man on the left wears a red coat and holds what appears to be a tuning fork. The woman in the center wears a plaid skirt, a white vest, and a black hat. The man behind her is also in a top hat. The woman in the foreground is reading from a songbook and is dressed in a green and black floral gown with a white neck ruffle. Other people pass by.
