1, thumb, ring finger, middle finger and forefinger pluck the strings in turn at a moderate speed.

2. Follow the metronome. At first, with the beat of 12/8, the metronome rings to play a note. When the speed reaches 240, use 3/4 time to change to 120 speed. Every time the metronome rings, the right hand plays four notes. Speed plus 10 or every 1 week 20. (Adjust according to your own strength)

3. Practice according to the teacher's method and find someone to practice.

Extended data:

1, when the left hand presses the string, the compound knuckles of each finger should be naturally bent, the first knuckle of the finger should be perpendicular to the fingerboard as far as possible, and the string should be pressed with the tip of the fingertip of the finger.

2. Straighten your thumb and hold the midline on the back of the neck with your fingertips as a support point for your left hand to exert force. The joints of index finger, middle finger, ring finger and little finger should be able to move and stretch flexibly.

3. Don't stick your left palm and tiger's mouth to your neck, and don't pinch your neck by "grasping" because it will reduce the flexibility of your left hand. The center of gravity of the left finger is placed on the thumb and middle finger, so that the two fingers can pinch the neck back and forth.
