When playing, squat down all over, support the piano bar with your left hand, place the bottom of the piano on the ground, and make the bar lean forward and form a 65° angle with the ground. Lightly step on the piano barrel or bottom column with your left foot to stabilize the piano body. The bow is played outside the strings.

The suitable tuning is in the range of g-e1, and the commonly used range is the fifth. The tone is rich and beautiful, closer to the male voice. Only the original position is used to play, and the tone is wider.

The left thumb gently presses the piano bar to reduce the tension of the strings, which can reduce the original sound by a minor or major second.

When playing the open strings, the tremolo is often vibrated, and the vibrato is especially characteristic. You can also twist the strings, that is, pinch the strings with your thumb and forefinger, stretch and shrink the two fingers, and use the right hand to move the bow to produce a vibrato effect. Quickly hit the strings with the middle finger, it can also produce a vibrato effect.
