VARESE/XENAKIS/LE CORBUSIER : "Poeme
Electronique"(1958).
Originally performed during the universal
exhibition of Bruxelles in 1958.
A mix of colors, lights, sounds, voices,
images and electroacoustic music.
As Le Corbusier said himself : "Le Poème
électronique se propose de montrer, au sein
d'un tumulte angoissant, notre civilisation
partie à la conquête des temps modernes".
////"Le poeme electronique proposes to
show,within a distressing tumult, our
civilization on her way to conquest modern
times"////

| Iannis Xenakis - Metastasis (Spectral View) |
 |
Metastasis or Metastaseis ("dialectic
transformations"), is an orchestral work by
Iannis Xenakis, a Greek composer-architect
and a major figure in the postwar development
of musical modernism worldwide. He is
particularly remembered for the pioneering
use of stochastic mathematical techniques in
his compositions, including probability
(Maxwell-Boltzmann kinetic theory of gases,
aleatory distribution of points on a plane,
minimal constraints, Gaussian distribution,
Markov chains), game theory, group theory,
Boolean algebra and Brownian motion.
Metastasis was inspired by Einstein's view of
time (a function of matter & energy) and
structured on mathematical ideas by Xenakis's
colleague Le Corbusier. The 1st and 3rd
movements don't have a melodic theme to hold
them together, but rather depend on the
strength of this conceptualization of time.
The 2nd movement does have some sort of
melodic element. A fragment of a 12-tone row
is used, with durations based on the
Fibonacci sequence (1,1,2,3,5,8,13,21,34...)
The preliminary sketch for Metastasis was in
graphic notation looking more like a
blueprint than a musical score, showing
graphs of mass motion and glissandi like
structural beams of the piece, with sound
frequencies on one axis and time on the
other. In this video I tried to display this
by presenting the frequency spectrum
(0-20.000Hz) of the piece and how Xenakis
actually "drew" music.
