The wearable device wraps around the musician’s wrist and provides haptic and light feedback to help the musician understand the conductor. 

The wrist is an ideal spot for a wearable device because this area has a fast reaction time to visual feedback and is an appropriate sensitive location on the body to deliver vibro-tactile feedback. The use of haptic feedback to provide information on tempo is a reliable alternative to an auditory cue (click track) which would lessen auditory cognitive load for musicians. The use of light is intentional as both music and color map to aspects of emotion. For example, loud, high energy sounds match with bright, vivid yellow hues while laid-back, quiet sounds match with muted, cool colors like blue.
