In the XX-th century means of audio-visual communication in art
were considerably renewed. Before when man used only 'natural'
means of communication, his functions were restricted to both set of
instruments control and supply it with his own (mechanical) energy.
Having mastering the audio-visual means of 'artificial origin' man
became free from power functions for they were provided by external
(electric) energy source. His actions at the moment were completely
focused on the control only. In accord with it the flow diagram of
an audio-visual system becomes more complicated. It includes a man
(M) who acts as an operator in both light and music channels, con-
trol panel (CP), control unit (CU), power amplification unit (PAU)
and output unit (OU). Analysis of possible interactions between
the corresponding components of these channels reveals in prin-
ciples of their synchronization the hierarchy as follows: 1) Physi-
cal sound visualization in OU (Lissajou's, Chladni's figures etc.);
2) Power amplification units (PAU) merging (the psychedelic light-
usic devices); 3) Automatic synthesis of light and music according
to a definite program put. in CU functions; 4) Synchronical music
accompaniment with sound by means of CP; 5) Synthesis on the man
level. Accordingly, the high artistic value extend is steadily grow-
ing, reaching in its limit the creature of the original light-music
works by an artist-man who can just use audio-visual polyphony ways
for it.
