The guzheng is a Chinese plucked zither with a history dating back to 500 BC. It has 12-26 movable bridges and is played by plucking the strings on the right side of the bridges with the right hand and pressing the strings on the left side with the left hand. In the late 20th century, guzheng music began to be taught professionally and new pieces were created from the collaboration of folk and professional musicians. The document then provides details on tuning the guzheng, numbered musical notation, playing technique, and an example musical score.
