Following the formal rules of dodecaphony, for the audio-visual installation Zwölftonform twelve sequences originate exclusively from twelve consecutive frequencies. For the visual translation and for presentation as an audio-visual installation, a sinusoidal waveform is abstracted and transferred along this formal concept. The increasing complexity gets visible and the prevailing simplicity gets almost inverted during the installation. The evolving aesthetic is punctuated with a dynamic grid, that divides the base with the value of the current sequence number.
