There are four steps to stick the flute film. Since the flute film itself has a certain degree of flexibility and water absorption, the pasted flute film will also have a certain degree of automatic restoration, so the film can be a little tighter when it is automatically restored. , the tightness of the flute film is moderate, but if you want to use it with the sticker, the flute film should be loosened to stick it. The specific sticking steps are as follows:

1. Cut the flute film. Use a needle to cut the membrane pair apart, and cut small rectangular pieces.

2. Knead. Use the thumb and forefinger of the right hand to gently knead into a small ball, twist the membrane into many fine wrinkles, and then gently unfold it.

3, stretch the flute film. After the membrane is restored to its original state, use the thumbs and index fingers of both hands to gently stretch it forward, back, left and right several times.

4. Film. Use donkey-hide gelatin to dip some water and wipe it around the membrane hole, so that the flute membrane pattern and the flute pattern are parallel to each other, and then stick it on the flute membrane.

Most of the flutes now use flute membranes. Dizi is an ancient musical instrument, and it is also the most representative wind instrument with national characteristics among Chinese musical instruments. One of the horizontal woodwind instruments commonly used in traditional Chinese music, the Chinese bamboo flute, is generally divided into the southern flute, the northern bangdi and the alto flute in between.

After the flute membrane is attached, when a column wave is formed in the flute tube to emit sound, the flute membrane also resonates due to the vibration of the column wave. The thickness of the flute membrane, the size of the membrane holes, the texture, the wrinkle and the tightness will all affect the sound, and the flute sound will be clearer and louder due to the influence of resonance.

The use of flute film, first of all, is to choose the adhesive. Currently, there are Ejiao, donkey skin paste, yellow fish glue, resin, Bletilla striata, garlic juice, glue, etc. Ejiao and Bletilla striata are the most commonly used.
