À propos de cette composition :

[Traduction française non disponible]
This piece is composed to the memory of my viola professor Tomás Alejandro Tichauer, who died in December 1994 at the age of 50 because of a heart attack.

Because the viola was almost a part of him, I chose the note "C" (basic tone of the viola) to organize the whole pitch-system that rules the work. This was thought as there were for this pitch two different overtones series: one positive (the real overtones), representing the presence of life and one negative or abstract (the inversion of the overtone series), which we normally don’t realize, representing the absence of life (his not being there any more).

Nummerical connotations in relationship with his name and his birthday serve to organize algorithmically the rhythms and also the pitches.

The materials used come from different sources but are all based on the note "C". There are concrete sounds, for example: 2 pizzicatti and one "sul ponticello" sound from the viola, 1 clarinet C and the first C Major chord of the Overture from Wagner’s "Die Meistersinger von Nürnberg". On the other side there are synthesized sounds, most of them treated with granular synthesis. The "C major chord" was transposed using a Phase Vocoder about 8 times higher and 8 times lower, following the order of the harmonics of C, in the positive (higher) and the negative (lower) way mentioned above. The equipment used for this piece (produced at the ICEM of the Folkwang Hochschule in Essen - Germany) was ProTools 4.0, Csound, Audiosculpt and SoundHack. Some passages were algorithmic composed using CommonMusic (Lisp).
