The black solid circle on the fingerboard indicates that the sound hole is fully pressed, the hollow circle indicates that the sound hole is open, and the half black and half white indicates that the sound hole is pressed.
Generally, the finger hole distance of an eight-hole flute is the first knuckle of the left hand, the second knuckle of the index finger, middle finger and ring finger of the right hand, and the first knuckle of the little finger. The thumb of the right hand is naturally placed between the index finger and the middle finger on the back of the flute.
The supporting point of the eight-hole flute: the supporting finger and the elastic finger should be completely separated, each performing its own duties and not mixed.
The six-hole flute has many supporting points, including five: lips, left middle finger, left little finger, right big finger and right little finger.
Eight-hole flute has few supporting points, only three points: lips, little finger of left hand and big finger of right hand.
The holes are counted from bottom to top. 1234567 is followed by the eighth hole.
Scale from low to high: 5 (low point, "bass Sao"): all press, "slow play".
6 (next point): Only open the first hole.
7 (low): Only one, two or three holes are opened.
1: Only one, two, three or four holes are opened.
2: Only press the six, seven and eight holes.
3: Only press the eighth hole.
4. Just press five holes, six holes and seven holes, and don't stick to fingering.
5: Fingering is the same as "normal blowing" of Bass 5 (next point), but the airflow is a little faster than it.
6: fingering is the same as bass 6 (the next point), playing slowly.
7: fingering is the same as bass 7 (next point).
Treble 1 (the last point): The fingering is the same as 1, which is too much.
