Mary Baker Eddy called the Victrola her "artificial singer" when it played the 23d Psalm and popular ballads of the day like "Home Sweet Home." The author, teacher, and founder of the Christian Science movement loved music and collected instruments from the late 19th and early 20th centuries. On display at "All in Harmony" are Eddy's Prescott upright grand piano, a Regina music box, Victor Victrola, pianola, and an interactive kiosk where you can listen to songs and instruments from Eddy's time. -- June Wulff, Globe Staff
