Keith McMillen Instruments introduces a complete series of bows for violin, viola, cello and bass – K-Bow communicates subtle gestures and elements of a string player's performance and uses them to control just about anything.

K-Bow is a hand-crafted composite sensor bow suitable for the most demanding player. Included with K-Bow is a comprehensive suite of software tools that provides a completely integrated creative solution for the modern string player.


"I am completely blown away by the K-Bow…One literally has the power to control and manipulate sound at their finger tips with virtually no disruption to the technical act of playing their instrument...It really is the coolest thing that I have ever seen."
Jeffrey Zeigler, Cellist, Kronos Quartet

K-Bow gives a detailed measure of every aspect of your playing: 

  • XYZ 3D Accelerometer - measures the playing force and angle of the bow
  • Hair Tension Sensor - detects how hard the bow presses against the strings
  • Grip Pressure Sensor - gives a measure of how hard you are gripping the bow
  • Bow to Fingerboard - a measure of the distance you are playing from the fingerboard via the antennas embedded in the bow
  • Bow Length - by interacting with the included fingerboard emitter, an infrared light sensor shows the distance from the bow frog to the strings of the instrument  
  • Bow Tilt - measures the angle of the bow, useful to know which string is being played
