前言乐器,聚集着人类智慧结晶与艺术感悟的伟大发明,从古至今经过了无数次的发展和演变,已经成为了人类诠释情感和陶冶情操的良朋益友。细数乐器的发展演变历程,我们可以从舂秋战国时期的编钟一直追溯到现代的电子合成器,这其间让人不得不感叹在科学与艺术之间,乐器也存在着一种很微妙的关系。根据各种乐器发出声音的物理规则,我们一般将乐器分为三种:声学乐器,电声乐器和电子乐器。其中,声学乐器所指的是乐手通过吹拉弹击等动作致使琴弦等物理介质产生振动而直接发出声音的乐器,如钢琴、小提琴、二胡、锣鼓等。电声乐器所指的是乐手通过演奏琴弦等物理介质使其产生 Preface Musical instruments, the great invention that brings together the crystallization of human wisdom and artistic understanding, have undergone innumerable times of development and evolution since ancient times and have become a good friend and friend for human beings to interpret their emotions and mold their sentiments. The history of the evolution of musical instruments in detail has been traced back to the modern electronic synthesizer from the chimes of the Qiuqian Warring States period, during which time people have to lament that there is a delicate relationship between science and art . According to the physical rules for the sound of various instruments, we generally divide the instruments into three types: acoustic instruments, electroacoustic instruments and electronic musical instruments. Among them, acoustic instruments refer to musical instruments such as piano, violin, erhu, gongs and drums which are directly emitted by a musician who vibrates a physical medium such as a string by pulling and pulling a shot. An electroacoustic instrument refers to the player who produces it by playing physical strings such as strings
