  • Patent number: 7605317
    Abstract: It takes great effort by players of a bowed string musical instrument to manipulate proper bow-to-string pressure that directly affects the quality of the sound generated. This invention is a training device that provides bow-to-string pressure reading as feedback to players. The device consists of a rib cage, a base unit, and a liquid crystal display unit. The rib cage emulates strings and transfers bow pressure to the base unit. The main components of the base unit include a pressure sensor and microcontroller circuit board. The liquid crystal display unit displays reading sent by the microcontroller board.
