Abstract
This paper proposes a wearable teaching system for finger's dexterous movement to play the piano. The teaching system is an exoskeleton type mounted on a hand and a wrist part of a piano player and then pushes his fingers to tap one or multiple key. Exoskeleton parts of fingers and wrist are activated by fifteen DC motors. A player can have an experience with more skillful and dexterous finger movements than what he has. As a preliminary test, simple tapping of five fingers are introduced in this paper.
