What's the difference between piccolo and Kong Di?

Piccolo is a vertical instrument in North Korea, and its shape is similar to that of the Dong flute. Korean is called "single sweep". Popular in Yanbian Korean Autonomous Prefecture of Jilin Province and other Korean inhabited areas.

The shape of piccolo is similar to that of Xiao, but the tube is thin and short, with a total length of 35 ~ 37 cm. Traditional short flutes are mostly made of bamboo, and some are made of hollow wood. The upper end is provided with a blowing hole, the pipe body is provided with five sound pressure holes (front 4 rear 1), and the lower end is provided with a sound outlet hole. You can only play a tune with five notes.

After the founding of New China, the sword piccolo was reformed, with a length of 34.5 cm and a caliber of 1.2 cm. The tube body is made of two bamboo tubes with copper sockets (between the blowing hole and the sound pressure hole above the tube body), and the pitch can be adjusted. There are 10 sound pressure holes (front 9, back 9 1) on the pipe body, of which 3 are closed holes controlled by keys. I can play seven-tone music and turn two or three keys. When playing, the right hand controls the 3-finger hole and 2-key hole on the upper part of the pipe body, and the left hand controls the back hole (thumb), 3-finger hole and 1 key hole on the upper part of the pipe body. The lower lip is pressed against the blowhole, and the wind hits the edge of the blowhole, which makes the air column in the tube vibrate and sound. When playing, you need to shake your head left and right to change the breath blown into the tube, thus producing a large-scale vibrato with unique characteristics.

The range of the keyed piccolo is (bb 1 ~ F3), and its timbre is soft, bright and clear. Can be solo, mostly used for national instrumental ensemble and song and dance accompaniment confusion. It is also often played with a flute that is eight degrees lower than it.
