{{main|Sympathetic string}}
Some instruments are employed with [[sympathetic string]]s—which are additional strings not meant to be plucked. These strings [[resonance|resonate]] with the played notes, creating additional tones. Sympathetic strings vibrate naturally when various intervals, such as the [[unison]]s or the [[octave]]s of the notes of the sympathetic strings are plucked, bowed or struck. This system is used on the [[sarangi]], the [[grand piano]], the [[hardanger fiddle]] and the [[Rubab (instrument)|rubab]].
