    This research aims to propose the concept of a breathing assist system for saxophone players with breathing problems. First, the quantity of pressure and air flow rate required to play an alto saxophone is determined by certain investigations and experiments. Second, the above-mentioned concept, which works like a pneumatic master-slave amplifier, is proposed and the details of each component are explained.

    This research aims to establish a Thai flute (khlui)-playing robot with realistic and natural sounds in traditional Thai style. First, an overview of the developed robot system is presented. Second, the refinement of the blown air flow rate control part, including the choice of the flow sensor, and its calibration method of dynamic characteristics are explained. Third, the refinement of the fingering control part is explained followed by an explanation of how to realize the expression, called glissando (i.e., gliding sound as a group of notes are connected). Finally, the proposed blown air flow control part and the proposed fingering force control part are combined, and the flow rate and the fingering force are simultaneously controlled to realize special sound effects, such as pure tremolo and vibrato.
