Home In 60th years in the USA the new direction in sphere of electronic music - computer music where in the beginning the sound was formed, created and stood out an electronic computer (I wish to remind that at that time the term "the personal computer" was absent as that) has begun to take shape. The Computer program was written by the composer together with mathematicians. The music realised by the big computers, in the course of such "titanic" work, was звукоотлична from any other forms and displays of electronic music. Therefore in the beginning it was offered to subdivide electronic music on is natural-electronic and computer (presently such gradation does not exist any more). One of impressing products Herbert Brana's "Infraslyshanija" are such.
