The tonality of the northeast suona tube is different from that of the hole behind it. Suona1* * has eight holes, representing different sounds. The barrel sound (that is, all eight holes are pressed) is the lowest note 5, and if one hole is released, it will raise a diatonic scale. The hole 1 below the D-tone bass 5 is D-tone bass 6, the hole 2 is D-tone bass 7, and then the D-tone alto 5 is below. When learning suona at first, put the thumb, index finger, middle finger and ring finger of the left hand on the suona, and put the index finger, middle finger, ring finger and little finger of the right hand under the suona. Press eight holes naturally with both hands to ensure no air leakage, then put the whistle in the middle of the lips, inhale at the same time, and vibrate and sound after blowing hard.
