Music and movement are intrinsically bound. When we make music, we carry out sequences of controlled movements with the aim of producing certain sounds. Playing the piano, for instance, involves moving your hands and fingers in a way that allows you to press the keys in a specific order. Of course, pianists make many other movements as they play—the arms, head, upper body, legs, and feet are often in near-constant motion. These movements may not be directly involved in producing sound, but they have both technical and communicative functions, shaping the tone that is produced, helping us coordinate with our co-performers if we are playing in a group, and communicating our expressive intentions to the audience.
