PROBLEM TO BE SOLVED: To easily generate high frequency sound, to generate vibrating sound and to increase expression capability of a three bridges single string musical instrument. SOLUTION: A necessary number of freely shaped sound holes is provided on the front plate side, a bridge A is fixed at an appropriate position of a small body side front plate and a bridge B is fixed at an appropriate position of a large body side front plate having a string tailpiece. The string is only fastened to the string tailpiece, is passed through at the tops of the bridges B and A and the tip of the string is connected to a pitch operating member which is used to determine the high and the low of the sound by manually adjusting the tension of the string. A bridge C is provided between the bridges A and B and a palm fixing member, which has a palm sliding stop member using a sharp angle, is provided on the side plate section of the small body side head section. The bridge C is provided at the 1/3 position of the string length between the bridges A and B toward the bridge A. By operating the pitch operating member, long string length/medium string length/short string length are provided to express from lowest sound "low sol" to "high sol" which is three octaves high.
