And to play it, we perform emotional gestures, jerky, linear, strong, weak : the very gestures that Béjart invented for dance”. This rhythm, I wouldn’t say that we write it so much as we devise it. What I means is, through live, naturally textured, intersecting sounds, arranged according to our will, we create an artificial tempo. It is a rhythmic quality imposed by rigid durations. “What is time in a work on magnetic tape ?” asked Pierre Henry in his diary Journal de Mes Sons (1979). Symphonie pour un Homme seul is the founding work of the Béjartian style, and will be performed by the BBL to complete this new programme. The artistic collaboration and deep friendship between Maurice Béjart and Pierre Henry, who is also known for inventing concrete music with Pierre Schaeffer, have made history.
