“SONUS SIX” is a digital referee for 12 tone serial composition. Users simply tap on a block releasing the sound contained within it, once released the block extinguishes itself. This continues until as per the rules of 12 tone composition, all twelve boxes have been utilised and they are free to return to play.
The software in part inspired by the work of Arnold Schoenberg, with “SONUS SIX” adding the dimension the unknown note contained in the box. Not only allowing for each note to be of equal importance but allowing the performer no preference of known order.
