ABSTRACT:
A tuning pin for pianos and like instruments being of the usual configuration except for the neck portion on which the string is wound which is reduced in diameter only on the side which the string leaves the pin thus forming a pin neck which is more elliptical than circular in shape, the reduced side of which has a less acute curve for the string to bend around and is closer to the center of axes of the pin which reduces the torsional effect of the string on the pin and subsequent slippage of the pin in the block.
