The string (16) is passed over the top of resilient extension (14) and connected to tuning post (26). As string (16) is wound around tuning post (26) tension is applied by resilient extension (14) keeping the end (18) of string (16) in place on bridge (22) and freeing both user's hands to attend to the winding process. A connector (42) for removably attaching the invention to the instrument (20) and a height adjuster (62) for adjusting the height of the resilient extension (14) are also provided.Type: GrantFiled: May 7, 2001Date of Patent: December 3, 2002Inventor: Edward C. Schindler

Patent number: 6437226Abstract: The present invention provides a method for automatically tuning a stringed instrument including the steps of inducing a signal on a string under tension to generate a resonance signal having an amplitude from the string and adjusting tension of the string in response to the amplitude of the resonance signal. The present invention also provides a system for automatically tuning a stringed instrument including a string, tensioning means operably attached to one end of the string for tensioning the string, and a processor for driving the tensioning means to induce a signal on the string and generate a resonance signal having an amplitude from the string and for adjusting tension of the string in response to the amplitude of the resonance signal.Type: GrantFiled: March 7, 2001Date of Patent: August 20, 2002Assignee: Viking Technologies, Inc.Inventors: Mark Oudshoorn, Jeff Moler, R. Glenn Akhavein

Patent number: 6291755Abstract: A tuner for stringed musical instruments which have a pickup for converting sound vibrations of the strings to electrical signals and a body being either hollow or solid with a front and back surface and a side surface extending between the front and back surface. The tuner has a tuner circuit attachable to an interior of the sound box with an input couplable to an output of the pickup and a digital display which displays a reference note closest to the note being played, a graphically intuitive indication of whether the note being played is above, equal to or below the reference note and a qualitative measure of the amount of deviation from the reference note. The tuner circuit automatically determines a closest note to the note being played and displays alphabetically the closest note.Type: GrantFiled: March 1, 1999Date of Patent: September 18, 2001Inventors: Arthur H. Hine, Timothy Collings, Carl Burdett, Brian Richardson

Patent number: 6278047Abstract: A microprocessor-controlled tuning apparatus for a stringed instrument, wherein the tension of a string is detected by a sensor, compared with a reference value, and readjusted if necessary until the detected value conforms with the reference value, thereby achieving a corresponding musical pitch.Type: GrantFiled: April 6, 2000Date of Patent: August 21, 2001Inventor: Todd Cumberland

Patent number: 6166307Abstract: An automated stringed musical instrument including a device for plucking the strings of the instrument, a device for fretting the strings, and a tension-maintaining linkage for maintaining the tension in the strings, such that the instrument can be remotely operated for extended periods of time without the need for operator control or re-tuning the strings.Type: GrantFiled: November 16, 1998Date of Patent: December 26, 2000Inventors: Kenneth B. Caulkins, Jeffrey M. Caulkins
