Secrecy and Confession of Silence in Performance
Symbolon, 2020 The creators of art play with the polarity of shown and hidden to attract the receptor of art in the alchemy of their opera. Crossing the borders of the words to the “unknown”, to the silence of the non-verbal performances, the public becomes connected with a spring of energy and significance that reveals a hermeneutics of silence in which we could ...
