Ways to make drums louder

At the beginning, you can loosen all the pull rods (that is, the drum screws), then turn the drum screws with your fingers until they can no longer be tightened, and then use the drum key to diagonally pass through the screws (just like the sequence when changing car tires) and turn them half a turn at a time. Put the drum on the ground or on the leg, tap the drum skin right in front of the drum ear with your fingers, and compare the overtone pitch produced in each place. Constantly adjust the drum screw until the pitch is similar when tapping along the drum edge.

When you level the tension on the drum surface, you will find that the trembling overtones gradually disappear. Our goal is to get clean and vibration-free overtones. Repeat this step for both drums, and then adjust all drum ears with the same tightness to adjust the overall pitch.

Drum is a traditional percussion instrument in China. According to the Book of Rites, there was a kind of "earth drum" in the early legend, that is, a drum made of clay. Because the drum has a good * * * sound, its voice is rich and loud, and it travels far, so it has long been regarded as a cheering force in the army by Chinese ancestors. According to legend, in the battle of Zhuolu, where the Yellow Emperor conquered Chiyou, "The Yellow Emperor killed Kui with his skin as a drum, with a reputation of 500" (The Century of the Emperor, volume 582).

The ancient war drums were all made of crocodile skin, and the crocodile skin was used as the drum skin, taking the ferocious habits of crocodiles to drum. In the Zhou Dynasty, according to the official map of Li Zhoudi, a "drummer" was specially set up to manage the drum system and drumming. Drums managed by drummers have many uses, such as thunder drums for sacrifice, spiritual drums for bands and golden drums. One of them, which is specially used for military affairs, is called Fen Drum. According to Shuowen, it is a kind of big drum, which is eight feet long, with a four-foot drum face and leather on both sides. In addition, there are Lu drums and Jin drums. It is also used in the military. These drums later developed into war drums of various specifications and were widely used in the army.
