Kristallwelt I includes musical processes which evolve from graphic patterns in combination with sounds of Asian percussion instruments. Just as in metal drop music, this composition is based on the contrast between sound-plains and complex, randomly-produced point-clusters too. Due to their complex overtone structures, the metallic sound character of these instruments very easily produced the visual impressions of light and color in their electronic transformations. Therefore, the compositional strategy followed a musical sound process from the beginning to the end of the piece, using increasingly brighter-sounding structures and timbres. I incorporated visual impressions into the forming strategy.
