ABSTRACT:
A string instrument having a tremolo which causes a rapid reiteration of the musical tone generated by the vibrating strings of the instrument so as to produce a tremulous effect. While the strings are vibrated in a direction transverse to their longitudinal axis for producing the basic musical tone, the tremulous effect is provided by adding a slow vibration to the strings along their longitudinal axis. For this purpose, a movable elongated member is coupled to the strings at one of their ends. This elongated member can be subjected to an appropriate movement for causing the desired tremulous effect within the strings. A drive mechanism automatically moves the elongated member at a selected frequency so as to vary the tension within the strings and render the tremulous effect.
