Le temps du miroir (2004)

for piano, live electronics
software design Joachim Gossmann
composition Luder BrŸmmer
commissioned by SARC, World premiere.

Despite the fact that this work is created out of different descriptions of sound all of them are of algorithmic nature. The sounds from the speaker are created with physical modells using strings. But not only the timbre was generated with the physical model. Each musical gesture, rhythm and dynamic is generated as a result of a mechanic description. A simple repitition for example can be created with a kind of pendulum. In case this pendulum is irritated by another object the rhythm would result in a less regular structur. The live part uses the piano either to trigger sounds or to be processed in realtime using a granulation technique. The piano part was generated through code algorithms describing all of the parameters used. The composition is created out of 4 sections without a separation. Each of these section performs the dominance of certain musical aspect. One is more melodic, another more rhythmic. Despite of this static identity processes are performed to move away from a certain layout of the structure. It was the idea of this piece to create a rich dense musical structure out of a preproced layer, a live interactive layer with preproced as well as live processed sounds and the performance of the piano player. Because all of the preproduced structure are not fixed together they can be treated dynamically responding to the interpretation of the performer. It was the aim to create a work with the quality of studio production and the flexibility expressive nature of a performance. Physical Model software "Genesis" was provided by ACROE, Grenoble. The work was created at the studios of the Centre for Art and Media Karlsruhe
