Stringed instrument practice bow guide

A stringed instrument practice bow guide for assisting students of stringed instruments in learning proper bow movement of a bow of a stringed instrument, comprising:

• a. a board having a finger end and an opposed brace end;
• b. a frame secured to the board;
• c. a bow track means secured to the frame defining a bow passage for slidably securing the bow of the stringed instrument within the bow passage, the bow track means being 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 the bow passage adjustably pivots with respect to a transverse axis of the board;
• and
• d. a pivot means secured between the bow track and the frame for adjustably securing the bow track to the frame in a plurality of fixed positions;
• wherein the frame comprises a base plate that defines a base plate slot for removably securing the frame to a reversible receiving bar of a frame mounting bracket secured to the board;
• a "U"-shaped track mount secured to the base plate having a first arm and a second arm and a frame strut passing between the first and second arms at a lower end of the track mount adjacent the base plate;
• and a first pivot rod passing through the first and second arms at an upper end of the track mount opposed to its lower end, the first pivot rod engaging a mount throughbore of a bow track bracket secured to the bow track to pivotally secure the bow track to the frame.

• a. a board having a finger end and an opposed brace end;
• b. a frame secured to the board;
• c. a bow track secured to the frame including a support housing secured to the frame and an enclosure housing pivotally secured to the support housing that pivots open to admit the bow and pivots closed around the bow to define a bow passage that slidably secures the bow within the bow passage, the bow track being 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 the bow passage adjustably pivots with respect to a transverse axis of the board;
• and
• d. a pivot means secured between the bow track and the frame for adjustably securing the bow track to the frame in a plurality of fixed positions.

• and
• d. a pivot arm extending between the support housing and the frame, the pivot arm defining a plurality of positioning notches within a notch cavity through which a frame strut of the frame passes so that whenever the frame strut engages a first positioning notch a longitudinal axis of the bow passage is adjustably secured within a first guide contact plane and whenever the frame strut engages a second positioning notch, the longitudinal axis of the bow passage is adjustably secured within a second guide contact plane.
