Abstract
A string tensioner for a stringed musical instrument is configured to apply a constant or near-constant tension to a musical string of the instrument. The string tensioner employs a primary spring that applies a primary force coaxial with the string. Each string tensioner also employs one or more secondary springs that apply a secondary force in a direction crossing the axis of the string. The secondary force has an axial force component that changes as the angle of the secondary spring changes. The primary and secondary springs are selected so that as the string changes in length over time the change in the secondary force axial component approximates the change in force applied by the primary spring so that the axial force applied to the string remains generally constant.
