Javier Alejandro Garavaglia

Overture (in memoriam T.A.T.) for quadraphonic tape (1997)

Genre: Acousmatic Music

Duration: 10:30


This piece was composed (like its sister piece T.A.T. [a man’s life]) 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 whole 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 as such, representing the absence of life (his not being there any more).


Numerical 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 up and 8 times down, following the order of the harmonics of the note C, in the positive (higher) and the negative (lower) way mentioned above. The equipment used for this piece (produced at the ICEM at the Folkwang Hochschule Essen - Germany) was Protools 4.0, Csound, Audiosculpt and Soundhack. Some passages were algorithmic composed using Commonmusic (Lisp).


The piece has been edited in the public domain commercially twice on CD, as shown below:
