1. The origin of electronic music

Electronic music originated from the late 19th century to the early 20th century. The earliest sound recording device can record sounds on the surface, but cannot play them back. It was 1857 The sonic recorder was invented by Frenchman Edouard-Lyon Scott Dumartinville.

The triode vacuum tube invented by Lee De Forest in 1906 was the first thermionic valve or vacuum tube, which allowed circuits to create and amplify music signals, broadcast radio waveforms, and calculate numerical values. and perform various other functions. In 1954, Stockhausen created his Study 2, the first electronic music work published in sheet music.

2. Principles of electronic music

Electronic music uses percussion instruments, noises from noisy instruments, and also uses human voices and concrete music to pass through sound filters. and reaction equipment to deform, deteriorate, and change it, and then cut it through other electronic instruments and recording technology to regenerate and combine it to form a work.

Spatial layout and transformation of electronic music:

Based on the static sound space layout of electronic music, the movement of sound embodies a variety of Characteristics of the movement space include various forms and trajectories. From the perspective of sound motion direction, there are co-directional motion (sound moves in the same direction) and reverse motion (sound moves in the opposite direction).

From the perspective of sound movement, there are transitional movement, horizontal surround movement (sound moves in a surrounding form in adjacent speakers), and vertical lifting movement (in three-dimensional speakers). In the spatial layout, the vertical movement of sound in two planes), etc.; from the perspective of the combination form of sound, there is a bit of motion line motion, band motion, etc. These motion space thinking are reflected in different electronic music works. ?
