【背景技术】【Background technique】
鼓是一种打击乐器，在坚固的且一般为圆桶形的鼓身的一面或双面蒙上一块拉紧的膜。鼓可以用手或鼓杵敲击出声。鼓在非洲的传统音乐以及在现代音乐中是一种比较重要的乐器，有的乐队完全由以鼓为主的打击乐器组成。除了作为乐器外鼓在古代许多文明中还用来传播信息。A drum is a percussion instrument covered with a taut membrane on one or both sides of a solid and generally cylindrical drum body. Drums can be struck by hand or with a drum pestle. Drums are an important instrument in African traditional music and in modern music, and some bands are composed entirely of drum-based percussion instruments. In addition to being a musical instrument, the drum was used in many ancient civilizations to spread information.
鼓是我国传统的打击乐器，按《礼记·明堂位》的记载，在很早的传说中，“伊耆氏”之时就已有“土鼓”，即陶土作成的鼓。由于鼓有良好的共鸣作用，声音激越雄壮而传声很远，所以很早就被华夏祖先作为军队上助威之用。相传黄帝征服蚩尤的涿鹿之战中，“黄帝杀夔，以其皮为鼓，声闻五百”(《太平御览》卷五八二引《帝王世纪》)。Drum is a traditional percussion instrument in my country. According to the records of "Book of Rites Mingtangwei", in the very early legend, "earth drum", that is, a drum made of clay, existed in the time of "Yiqi". Because the drum has a good resonance effect, the sound is fierce and majestic and the sound travels far, so it was used by Chinese ancestors as a cheer in the army for a long time. According to legend, in the battle of Zhuolu when the Yellow Emperor conquered Chiyou, "the Yellow Emperor killed Kui and used his skin as a drum, and he heard five hundred voices" (Volume 582 of "Taiping Yulan" cited "Emperor Century").
