Abstract
Abstract 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.
