The guide has two arc shaped inserts that may be made of a flexible material and that removably fit within a pair of opposed bouts. A pair of holes is provided in each insert for selective fit of a pair of memory strands that arch above a highway of the strings. A range of desired spacing above the strings is provided by both an insert thickness of the inserts relative to a depth of the bouts and also by a selective fit of the strands within the inserts. The bow guide is selectively disassembled or collapsed to fit within a case of the string instrument.
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.

Abstract: A bow guide for a violin is made from resilient material, such as a unitary piece of foamed plastics, and comprises a support means for elastically securing under the overhang of the fingerboard and upstanding guide means protruding in use upwards from ends of the support means so as to guide a bow in a desired region of the strings. One, two or four guide means are possible, two being preferred.
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.

At least one of the parts (2,3) of the stick is extended in the form of an arm (5) from the axis (6) and the arm (5) can function as a lever for tightening the hair (4) of the bow by the performer's exertion of pressure between the arm (5) and the other part (2,3) of the stick.
Abstract: A stringed instrument practice bow guide is disclosed for assisting a student of stringed instruments in learning proper movement of a bow of the stringed instrument without aggravating noise caused by improper string crossings. In a particular embodiment the stringed instrument practice bow guide includes a board having a finger end and an opposed brace end; a frame removably affixed to the board; and, a bow track defining a bow passage for slidably securing the bow. The bow track is pivotally secured to the frame so that the bow passage is in a fixed, right-angle relationship with respect to a longitudinal axis of the board and adjustably pivots with respect to a transverse axis of the board. A pivot arm extends between the bow track and the frame to secure the bow track in a plurality of fixed positions relative to the transverse axis of the board.
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.
Abstract: A violin bow guide has a rod (38) which is attached to the back of a bow (58). The rod (38) travels through a rod guide (36) which is held in place over the strings of the violin on a support (11) which attaches to the body of the violin. The rod guide (36) is pivotally mounted to permit the bow (58) to play on all the strings. Means are provided for adjusting the height of the rod above the strings, the position of the bow between the bridge and fingerboard of the violin, and the amount of resistance to movement of the rod through the rod guide. The rod guide (36) can be locked at a selected height above the strings or permitted to float freely up and down.
