| 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.

| Iannis Xenakis Interview (1 of 3) |
 |
An interview with the composer Xenakis. (1 of
3)
The interviewer is Harry Halbreich (Belgian
musicologist)
Not sure who "owns" the footage so I claim
"fair use".(original title said "By GK",
appears to be from 1995)
Original footage not well shot or edited so I
have reframed some of it and added some
pauses (for emphasis).
Also I have peak limited the audio and added
new titles (the music underneath is Xenakis,
but which piece?, answers on a postcard).
The original was one file and was higher
res/less compressed but wouldnt fit on
YouTube (276mb) so I had to split it into
three.
I will try and find a free server to upload
the whole file to at some point.
