Based on the concept of Eunjin Yoo, I wrote two mathematical poems. My mathematic poems formed the basis for our performance: The Sound of X.  Eunjin Yoo is a South-Korean visual artist situated in Munich. For this performance she was interested in how sound is based on friction but that the perception of it still differed. 
‘How is it that we conceive the sound of a bomb differently that then sound of a wave?’
