A stringed instrument includes a body, a string, a string exciting device and a bridge. The body supports the string, the string exciting device and the bridge. The string has a scale length determined by a distance between a first support point and a second support point. The string exciting device is designed to be driven by an electrical signal having a certain frequency and vibrate the string by applying an excitation signal having a frequency corresponding to the frequency of the electrical signal. The bridge has the first support point and a surface located between the first support point and the second support point and designed to come into contact with the string during vibration of the string.
