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. However, when the shaft is moved along a path departing the aforementioned path a discernable resistance to this movement occurs due to the shaft contacting the walls of the passageway so as to signal the student to reposition the shaft for movement thereof along the proper path.
