There have been many attempts to make mechanical systems play music like music box or orchestrion. In the past, the main purpose of such mechanism was that they should give easy means to hear music nearby. But music will give us two kinds of benefits, those are, "listening music" and "playing music". The authors have been developing some music performance robots, for example, Saxophone Playing Robot and Trumpet Playing Robot. In this study, we are going to develop a play assist robot for a dystonia patient of a professional sax player. This system uses an artificial mouth device that can be controlled through the external controller by the player and the saxophone should not be remodeled. The player will use pressing down motion of his foot to control the artificial lip pressure on the reed and twisting motion of his leg to control the point of action of the reed pressing force.
