A tremolo device for use on a musical instrument having a neck extending between a body and head, and a plurality of strings under tension aligned with the neck includes a bridge structure resiliently supportable relative to the body for rotation about a pivot axis transverse to the neck. String retaining elements of the bridge structure are movable therewith, each being dimensioned and arranged to engage a corresponding string. An actuating lever extends rearwardly from a point of attachment to the bridge structure to a point further from the neck and pivot axis than the point of attachment. Lifting of the actuating lever by an upward force exerted by a strumming or plucking finger reduces tension in the strings and lowers the tone of the musical element and exertion of a downward force upon the actuating lever increases tension in the strings and increases the tone of the musical instrument.
