"TI" and "KA" are the base of a method for teaching rhythm in the Hindu culture. These two syllables are juxtaposed and combined in many ways to create rhythmic cycles that can become highly complex. In this piece, my intent is also to retain the poetic idea of "CHAOS" that seems totally appropriate in a configuration uniting a percussionist and a 5.1 system. This mixed piece is essentially a reflection on space, rhythm and sound projection in a virtual environment. By extending the percussion with a recording, it is quite possible to create numerous rhythmical illusions, as well as complex polyrhythmic structures attaining such density that the whole sound space becomes saturated.
We live, day to day, in a three-dimensional sound environment, and therefore, it seems interesting to consider the sounds, as well as their layout in that sort of an environment. For that reason, I chose to work with a 5.1 multichannel system rather than a stereo system.
Transforming the percussion timbres with powerful sound treatment tools allows me to play with the listeners' perception, sometimes bringing them into a universe close to the instrumental sounds and other times transporting them into a much more electronic world. I strongly believe that in this case, using only non-pitched percussion instruments is a good solution for finding acoustic unity with the tape.
