![]() ![]() This image is taken from the documentary by Patrick Saint-Jean, the engineer who designed the UPIC together with Xenakis.Īpproach – Compared to pre computing experiences I mentioned before, the UPIC stands out with a much simpler approach. A screenshot showing the outline of the UPIC system. An old picture that shows the structure of the UPIC system. The translation was done in music through some basic steps: (1) the digitization of drawings, (2) the association of graphs to specific musical parameters, and (3) listening to the audio signal after conversion from digital to analog. ![]() In other words, graphical representations, arbitrary, they were used as symbols of specific musical events, exactly as it would be with the UPIC.ĭrawing the music – The UPIC, which stands for Unité Polygogique Informatique du CEMAMu, was a tool that allowed you to translate drawings made on a common electronic whiteboard in a musical piece, similar to that used by many others CAD/CAM software. Describing the procedure used for this work, Xenakis actually gives us a description that can be applied perfectly to the UPIC system: he explains that the creation of arborescence procedure needed of a code, which established a crepresentative orrespondence between the graphical units and a certain instrument, or even a groups of instruments. In this way should be mentioned also the processes of arborescence (developing procedures based on the multiplication and repetition of minimum units) adopted in some compositions of the seventies, in particular with Noomena (1974) and Erikhthon (1974). …and music – The first time in which Xenakis adopts a graphic writing for the composition of a musical work was in the mid-fifties with Metastaseis (1953/54), work realized through the definition of graphic elements then translated into music, thereby effecting an operational mode that appears as a kind of model with respect to what happen with the UPIC system. ![]() The writing surface of the Upic system is also a new methodological approach to music teaching, as often highlighted. ![]() That’s the idea of transferring this approach in music composition arose as a natural fact, it has also highlighted Xenakis himself. Training as an engineer, and the important experiences in the field of the architecture alongside Le Corbusier, had already brought the use of drawing as a constant in the life of the composer of Greek origin. In fact, this encounter between art and music, which is the heart of the UPIC system, takes place in years prior to those of its realization, and following some experiences not only involved in musical composition. *Preventative care services such as immunizations or wellness exams are not covered at walk-in clinic/urgent care visits.Ī complete list of urgent care clinic locations is provided below.Drawing… – A fast reading of the biographical notes of Xenakis, allows us to grasp certain elements rather interesting, useful in particular to understand that the construction of the UPIC arises, in the experience of Xenakis, as the result of a course not very accidental. Look below for more information on when to use walk-in clinics vs. General Med, Internal Med, & General Pediatrics You can access any CVS Minute Clinic, Ingalls Quick Care, and additional urgent care clinic locations for walk-in clinic/urgent care visits providing easier access to urgent care when needed and if you don’t live near the University of Chicago Medical Center.Įndocrinology, Family Medicine, Internal Medicine, & Gynecology ![]()
