ABSTRACT:
A system for tuning pianos and other string instruments utilizes a clamp-on probe with a feedback loop to induce a controlled vibration of the string and its natural frequency of vibration. This frequency is electronically compared to an accurate reference frequency. An associated electronic circuit controls an electric motor driven mechanism which adjusts the string tension until the correct frequency is achieved.
