String Quartet No.2 "Contra-statement" by Turgut Erçetin

“Contra-statement” engages with the issues of complexities that are perceived at resonance rate. The residual signal produced at certain fingerings, which consists of discrete resonance peaks, constitutes a pitch perception due to its spectral structure. The analyses show that such a peculiarity can be designed to produce a harmonic relationship between "virtual" and physically played pitches if accurate filtering methods, such as bowing or specific fingering combinations, are applied adequately. As an acoustic piece and as a piece investigating the acoustics of string instruments, "Contra-statement" aims to explore the concept of "perception" and the way it communicates with this acoustic-temporal output.

“Contra-statement” is dedicated to all fellow artists who are currently held in prisons in Turkey, where the Ministry of Interior Affairs, İdris Nedim Şahin, officially stated that art is a form of terrorist propaganda on December 26, 2011.

Above performance was given by the Arditti Quartet on July 1st, 2012 at IRCAM.
