The interval of the fourth pressed sound hole is two degrees higher than that of the third pressed sound hole, and the interval of the fourth pressed sound hole is also two degrees higher than that of the fifth pressed sound hole. According to the vertically-blown Ba-wu flute, the ten sound holes can be controlled by ten fingers, the aim of widening the range can be achieved without adding control keys, the unique glissando effect of the national wind music can be achieved through playing, modulation is easier due to the interval arrangement relation of the vertically-blown Ba-wu flute, the playing range is expanded to 15 degrees or 16 degrees from the original 11 degrees, and therefore the requirements of players are better met, and the music expressive force of the vertically-blown Ba-wu flute is greatly enriched.
