  • 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.
