  • 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.

  • Patent number: 6777600
    Abstract: A teaching device for bowed string instruments includes a base connected to a finger support by a stem. The base is used to attach the teaching device to a bow for a bowed string instrument. The base has an outer end and an inner end and a central opening therebetween that receives the bow. The central opening has a longitudinal axis that is parallel to the longitudinal axis of the bow when the base is attached to the bow. The finger support has hollow body with a closed lower end and an open upper end and a central cavity between the two ends. The central cavity has a longitudinal axis that is positioned at an angle of less than 90° to the longitudinal axis of the base. The player's little finger is positioned within the central cavity of the finger support, which forces the little finger into an angled position with respect to the bow and teaches a player how to maintain a proper grip on the bow.

  • Patent number: 5355757
    Abstract: A device for practice bowing a stringed musical instrument for the purpose of teaching the movement of a real bow along a path perpendicular to the strings on the string instrument while maintaining a fixed sounding point. The bowing practice device comprises an elongated shaft simulating the ribbon of horsehair on a real bow. This shaft is movably supported in a sleeve which has a groove in the outer surface thereof for receiving a string of a string instrument. The string is held in the groove by two elastic O-rings supported on the sleeve. The movement of the shaft along a path essentially coaxial with the passageway through the string-positioned sleeve provides for movement of the practice device along a path essentially perpendicular to the strings on the string instrument.
