Perception Key: Swing Low, Sweet Chariot Study an image of sheet music for “Swing Low, Sweet Chariot”. Answer the following questions: What is the proportion of tonic notes (F) to the rest of the notes in the composition? Can you make any judgments about the capacity of the piece to produce and release tension in the listener on the basis of the recurrence of F?
