Music in which sound is generated, transferred, triggered, or amplified by electronic devices. The creation of electronic music may involve the use of magnetic tape or digital technology and whose reproduction involves the use of loudspeakers. For works created with only natural sound sources recorded and manipulated via discs or magnetic tape use "musique concrète." For music created entirely through the use of a computer, in which the sound is initiated purely through digital means, use "computer music."
