THE
CONCEPT
OF
'ALEA'
IN
BOULEZ'S
'CONSTELLATION-MIROIR'
BY ANNE TRENKAMP
THE USE
of chance techniques by contemporary composers has
bewildered
more than a few theorists and
driven others to silence.
Some
musicians
would
agree
with Edward T.
Cone
that,
since
chance
music
has
no
definitively
ordered
sequence
of
events,
it can
only
be
described,
not
analyzed.,
Others
would
agree
with
Anthony
Cross:
The
preoccupation with chance
on
the part of composers like
Stockhausen
and
particularly
Boulez,
pinpoints
the
chief problem
faced
by composers
of
the
so-called post-Webern school: with
the
abandonment
of
tonality,
of
all
pre-existing
language,
how
is
the
composer to achieve the meaningful articulation of form?2
The
problem
of chance
in
music
is
particularly crucial for twentieth-
century
scholars.
In
the
past, major
musical
issues
have
been avoided
by negative
means:
tonality
became
atonal;
themes became
athem-
atic; rhythm
became
arhythmic.
Only by linguistic feats such as
'open
form', 'circular
form' and
so on has form not become 'aformal'.
By examining
one
composer's
confrontation
of chance the relation-
ship
between the
articulation of
form
and
chance can be seen from a
more positive viewpoint.
Boulez
has
made a
distinction
between chance and alea
in
his
speeches
and
essays.
For
him,
al6a
is the use of
chance under
highly
controlled
circumstances. While this
distinction
appears
on

surface to
be nothing
more than linguistic hairsplitting,
the
signific-
ance of
the differentiation becomes
apparent
in the analysis of a
work such
as 'Constellation-miroir',
the third
and central movement
of Boulez's Third Piano
Sonata.3
Close examination of
some ideas
Boulez wrote about at the time he was composing the sonata and an
analysis
of
'Constellation-miroir'
make clear
the
necessity
and
validity
of the
distinction.
In
addition,
an
analysis
of this movement
illustrates
one meaning of the term 'open
form'.
An earlier work
by Boulez,
Structures or
two
pianos
(I 95I-6),
illustrates the composer's
attempt
to serialize rhythm, dynamics
and
attack
in
addition
to pitch. During the completion
of Structures,
however,
Boulez was
already re-examining the
validity of
the strict
serial
procedures
he
was employing
at that
time; his
writings show a
concern with this problem until the composition of the Third Piano
Sonata
(c.
I
960).
First,
Boulez
challenged
the
conclusions
serial
composers
drew from Webern's
works and the
manner in
which
they
'extended' his
procedures:
The
model universally
chosen
is Webern: and
in
his
music the
principal
matter
for
study
is
the
organization
of the
musical
material.
Certain conclusions are arrived at, and
these are
then
deliberately
developed by
a
process
of extension.
With
real
frenzy
we set about
[serial]
organization as
if
we were on
the
threshold
of
undiscovered
worlds ... Webern organized only intervallic relationships; we now
subject rhythm,
tone-colour and dynamics
to
[serial]
organization.
All
this serves as
fodder for the monstrous
multiple
organization
which must
be renounced forthwith
if we are
not
to
condemn
our-
selves to deafness.4
Second,
he
questioned
the
relationship
between the
serialized
elements
and
the
perception
of
the
total form:
Each system,
carefully
worked
out in its own
terms,
could
only
cohabit with the others through a miraculouscoincidence. The works
of this
period
also
show
an
extreme
inflexibility
in all their
aspects;
elements
in
the
'magic squares'
which
the
composer,
with his
magic
wand, forgot
at
the
birth
of the
work,
react
violently
against
the
foreign
and
hostile
order
forced
upon them; they get
their own
revenge:
the
work does
not achieve
any
conclusively
coherent
organization;
it sounds
bad and
its
aggressiveness
is
not
always
intentional.5
These
are bitter
thoughts
from
one of
the
technical
masters of
'total serialism'. What Boulez specifically attacked was the applica-
3 Only
two
of the proposed
five
movements
have
been
published:
'Trope'
and
'Constellation-miroir'.
The
latter is
designed
to
be
played
either
forward
or in retrograde,
but only
the
retrograde
has been published.
Both were
completed
by
I96o.

tion of twelve-note
pitch technique
to the
materials of
rhythm, colour
and dynamics,
because
each
of these materials
has a
different inner
structure.
Pitch material in
this style
is
a
closed
system
of
twelve
chromatic pitches whose different
permutations
produce associative
elements at will. Rhythm, on the other hand, does not contain such
a closed
system
of
separate elements; to
enforce upon
rhythm the
same
procedures that
govern pitch
cannot
produce the same
necessary conclusions.
This
point
of
logic applies to colour and
dynamics
as
well.,
When
composers
tried to use the
same
procedures
for
all four
elements mentioned
above,
there
was no
logical
or
necessary
relationship
between
them.
The
resultant 'chance
by
inadvertence'
occasionally produced
homogeneous and logical
simultaneities,
but not
by
rule of the
composer.
Boulez, however, did not reject serial technique completely; his
arguments
primarily reject
the
excesses
of a
system
which
re-
linquished compositional
decisions to a series of
calculations and
tables.
For
Boulez,
the
extents
and limits
of
serial technique
displayed
in
Structures rovided not
a
dead end,
but a new begining: 'Serialism
provided me with
a
syntax.
In
"Le Marteau",
I
used it
to formulate
thoughts'.7
The
syntax provided
by
Structureswas
actually
a re-definition of
the role of
the
series.
In
'Musical
Technique'
Boulez
presents
still
another definition of the series that illustrates this role; he stresses
the
importance
of
hierarchy
within the series
rather
than
the
primacy
of
pitch-order:
The
series
is
...
the germ of a developing hierarchy...
,endowed
with a
greater
or
lesser
selectivity,
with
a
view
to
organizing
a
FINITE
ensemble of creative
possibilities
...
;
this
ensemble
of
possibilities is
deduced
from an
initial series
by
a
FUNCTIONAL
generativeprocess
(not simply
the
consecutive exposition of a certain
number of objects,
permutated according to restrictive numerical data)."
Boulez's
redefinition
of the series has
direct
bearing
on
the
analysis
of
'Constellation-miroir'.
First,
the
recognition
of interval-
class
and/or pitch-class hierarchy
as
opposed to pitch-order demands
a
reformulation of the
role
of pitch within a piece.
Second, since it is
the interaction between
musical
elements that
produces form, any
change
of
approach towards one
or
more elements is
bound to affect
the
manner in
which a
composition
as a
whole is
organized. Thus,
the new role of
pitch
and
the
disavowal
of the
serialization of other
elements invite
special
attention
to the
formal
organization.
Boulez has
stated that his
concept of form at
that time was

influenced more by literature
than
by other composers,
especially
by Stephan Mallarme. 9
He felt that writers had explored structural
possibilities far more extensively
than composers, and
in
Mallarme
he found a system of organization suggestive of what he was
attempt-
ing in 'Constellation-miroir'. In 'Un Coup de des', the poem after
which 'Constellation-miroir' is modelled, two facets of poetic
usage
have bearing on this analysis.
First,
Mallarme
transposed words
from their everyday associations
into verbal objects with a poetic
function by concentrating
on phonemic qualities and by juxtaposing
words
in
a manner which gave them a multiplicity of
meanings.10
Boulez's
task was
not
dissimilar;
he transposed pitches
from
their
serial
matrix
into
the
phonemic
state of the smallest recognizable
unit of
pitch relationship,
serial or non-serial: the interval.
Second, Mallarme in 'Un Coup de des' segmented phrases and
arranged them on the page in such a way that the connections
between
phrases
would
be
ambiguous. For example, if
a
sentence
is
diagrammed in the traditional
way, the words are segmented and
additional words
are
joined
to them to designate their function.
Even if the words are presented
in an unusual order, the functional
designations make the meaning clear:
verb direct bject subject
took
the bread
I
uickly
to
my
house
adverb
prepositionalhrase
In
'Un Coup de
des',
the sentence is fragmented, but there
is no
explicit relationship between
the fragments, except for
a certain
typographical hierarchy:

Despite the
seemingly
fewer choices in the
Mallarme
poem,
the
musical continuity
in
'Constellation-miroir'
has been segmented
in
the same fashion, and the choices
of
segment-sequences
in
perform-
ance create
ambiguity similar to that
found
in the Mallarme poem.
Interesting as these artistic influences are, it is the process
through
which Boulez turned to aleatoric procedures that is im-
portant. Boulez
stated: 'Actually, the only thing
one can play upon
is the interaction between style
and form'.
12
He developed
a post-
serial style
and
sought-by
analogy perhaps-a formal procedure
with which it
could interact. The result of this
search was a particular
form
of chance
called alea,
in which the composer controls precisely
the
areas
in
which
chance
may enter into the composition."I Alea,
then,
was not an outside influence, used in
and for itself. Rather,
it
was the adoption of a literary viewpoint to create a formal procedure
which could interact with a particular style.
The intrinsic use of
alea
as a formal
device in 'Constellation-
miroir' can be seen by a glance
at the score. The idea of
an open-
form,
aleatoric
movement is
enhanced through the typographical
layout of the
movement.
The score consists of nine pages,
i8 ins.
x
24 ins.,
over
which
58 segments
of
varying
length
are
arranged.
These segments
are
printed
in either red or
green, red standing for
the chordal
blocs
sections and
green for the points sections of
pointil-
listic texture. Signs before and after each segment mark the routes
that
can
be taken.
In
addition
to the many
signs surrounding the segments,
two
different
types
of tempo
indications are used. First are the
specific
tempo
modifications often found
in
the
blocs
sections; these
may
indicate rapid changes of tempo
in a
short space,
as

All of these
signs add
to
the
visual
complexity
of the
score.
The use
of
different
colours
and the
resemblance
of
the
layout
of
the score
to extra-musical
elements
provide
additional
amusement
for the
performer;
the
multiplicity
of
signs
gives
the
illusion
that
the
pianist
has
more choices
than
are
really
important
or available.
At
the highest
level
of
organization
there
are six
sections:
Melange,
points
3,
bloCs ,
points 2,
blocs
and points
;
these
sections
must
occur
in the order
stated.
At the
next
level,
individual
segments
are
linked
together by the other segments in whose company they are allowed
to
occur.
Thus,
although
a
section
may
have twelve segments,
these
linkings
may cause
the
segments
to create
three
units.
Within
these
units,
the
choice
of order
for
individual segments
may
remain
free.
For example,
Milange
has six segments.
The
pianist
must
start
with
the first segment
and end
with
the sixth.
Of the
remaining
segments,
the
third
must follow
the second
and
the
fifth must follow
the
fourth.
Segments
2
and
3
belong
to
one
textural
density
and
segments
4
and
5
to
the
other.
Thus
there
are
only
four
units
and
only
one
choice;
the choice is whether segments 2-3 will precede or follow segments
4-5,
or,
in
other words,
which
density
will
come
first.
The
other
sections,
by
the
very
nature of
the
signs
which
surround
them,
divide
into
units
in the
same
way.
When
unit
groupings
are
taken into
account,
there
are
actually
only
17
units,
although
there
are
58
segments.
The following
table
shows
the number
of
segments
and
units
in each section:

Tempo does not really
affect the
number of units. Of the
two
types of
tempo
modification discussed
earlier the first occurs within
a
segment. The
frequent changes
in tempo
measure the time
relation-
ship between
chords or pitches
(see Ex. i). In music
with
a
basic
pulse this measurement is accomplished by the rhythmic values
assigned
to pitches. In his
earlier
compositions Boulez's notation
was
characterized by
highly
complex rhythms in music
that sometimes
lacks a
basic pulse. He found
that the
realization of these rhythms
in
performance was an
approximation of the
notation and that
simpler
notation,
combined with
fluctuating
tempo, would serve
him
better.
1
As
a
result, the
rhythmic
notation in this movement
has
actually been
simplified.
Fluctuations in tempo
replace many of
the
earlier,
complex
rhythmic patterns; in
their place
one finds
simple
quavers or semiquavers.
The connective,
'if . . . then' tempo
indications
between two
segments (see Ex.
2) might
appear to be a further
usage of chance
techniques, but
their primary
purpose is to assure a
smooth
transition
from one segment
to the next.
Since the order of
segments within a
unit
is
not
predetermined, tempo must
be
considered within the
multiple
possibilities of contexts
for each
segment. This planning
can
be
seen
in
the two
choices offered by
Boulez for the
main unit of
points2 (in
the
diagram each crotchet or
quaver
represents a segment):

_
The
pianist,
then, actually
has far
fewer
choices
than one
would
expect from
the
notation of
'Constellation-miroir'. While there
is
choice
among
individual
segments,
the
organization of
these
segments
into
units
prevents
random
chance and
provides a
sub-
formal
structure.
In
addition,
the
tempo markings,
which at

glance
appear to promote the
use of chance,
perform two long-
established
functions:
the control of the
rate of musical
events; and
the control
of smooth transitions
between
segments.
To this point we have eliminated some misunderstandings about
the use
of
chance in 'Constellation-miroir'
and have determined
how
many genuine
notational choices
are given.
In short, it has been
shown
that Boulez has loaded the dice.
To determine the extent
of
the loading
an
examination of the pitch
structure
is necessary.
Boulez has stated that
his prime
concern with serial organization
in
this
piece
was
to
create
horizontal
and vertical
sonorities related
to
each other
in
a
manner that could be perceived
by the listener.
15
If
this movement
is
to
be considered serial, it
must
be considered so in
light
of Boulez's definition
of the series,
with its emphasis
on
hierarchy as opposed
to pitch-order.
The
pitch organization
of 'Constellation-miroir'
is similar to that
of 'Trope', the
other
published
movement of the
Third Piano Sonata.
The same series
can
be considered
the foundation
from which Boulez
develops
his pitch
material:

The
four
main subdivisions
of
the chromatic
set,
when reduced
to
an
unordered,
elemental
state,
consist
of:
(a) two semitones
and
a
perfect fourth; (b)
an isolated
pitch; (c)
a
pattern
of
tone, semitone,

and
(d)
two semitones.
In
addition,
the
second
and

elements
of the series
can be
combined,
forming exactly
the same
intervallic relationships as the first element.
From
these initial
pitch
elements
Boulez creates
short,
easily
recognizable
patterns
that
are
repeated
vertically
or
horizontally
at
random;
the
only
hierarchical
organization
is the
inclusion
or
exclusion
of
certain
intervals,
or the
favouring
of a few
intervals,
such
as
the
minor second.
This
type
of
technique-the
use of
basic,
simple
intervallic
structures
as
a
replacement
for the
more
highly
organized
serial
pitch
structure-has
been
seen
as an extension
of
Webern's
ideas.

It has also
been considered
related
to the
investiga-
tion of the phonemic quality of words by Mallarme.'7 The pitch
structure
results
from
units
so basic
that
they
can
not be
broken
down

Discussion of prominent pitches and intervals alone does not lead
to
significant insights
about
Boulez's
piece.
Two
points
should be
noted,
however.
First,
the
lack
of
definitive,
hierarchical
pitch
organization
results in a bland
uniformity
of horizontal and vertical
pitch structures.
This
uniformity
allows basic sonorities to be
easily
grasped by the
listener,
unless the texture becomes too dense.
At
the
same
time it offers an ideal
background
for textural
manipulation.
The
absence
of
a
strong
hierarchical
plan
makes
possible
the
reduction
in
emphasis
of the
very
element to which we are most
attuned: pitch. Second, there is a basic difference in the pitch
organization
of the
principal
points
and blocs
sections.
The
points,
through
their
sparser
texture and concentration on the
horizontal,
allow
the listener
to
perceive
at
least
part
of the
pitch
structure.
Many
of
the
blocs,
on the
other
hand,
are
so dense that
pitch compre-
hension is impossible; these dense sections correspond
in
Boulez's
terminology
to
ordered
chaos.
In
this
manner
the
pitch
structure
does
support
the main
structural
divisions
while
remaining
a
secondary
element
suitable for textural
manipulation.
Each texture is further reinforced by dynamics and range. The
points
sections
employ
moderate
dynamics
and
a
middle
register,
while the blocs
use
extremes
of
both
dynamics
and
range.
Within
each section various
facets
of each
type
of
texture may
be
presented,
allowing
subtle
differences
in
texture.
The
structural organization of
this
work, then,
depends upon juxtapositions
of
textures.
Since
pitch
organization is not
a
major determinant, especially at the subformal
level, the options left open to the performer are really of little
significance.
To be
sure,
different
routes will
cause higher or lower,
slightly more dense sonorities to be heard in different orders, but
since
textural
organization
does not
create the
same degree of
expectation
as
pitch organization the choices have a minimal effect
on
the
perception
of
form.
The
basic six-part structure of alternating
textures remains
primary.
This is the way Boulez has
loaded the dice of chance: he has only
conceded
to
the
performer the things that do not matter; the

perceptible
structure
is
decided by
Boulez himself.
The
structure of
this movement
is no
more 'open' than
the other
compositions
were
'closed' structures,
unless
one
is to substitute
'pitch-orientated'
for
closed and 'non-pitch-orientated'
for
open.
The composition has
an
ordered succession of textures. The movement consists of six sections.
The
first, Milange,
introduces
the
two textures, the
first
of which can
be described
as
sparse
and
pointillistic,
and the second as
more
dense
and chordal.
These two
basic textures
are
presented in
alternation
for
the rest
of the movement,
ending with
a pointillistic
section.
The
variety of orders
possible
within each
section
gives renewed
interest
to each
section
without
removing
a
sense
of structure.
The conclusion
is inescapable
that 'Constellation-miroir'
is
composed
within a strong
structural
framework.
Aleatoric
proced-
ures do not weaken the structure, especially at the highest formal
levels. The term
'open form'
has
no relevance
here,
unless it is
re-defined
as referring to
a composition
whose
structure is
determined
primarily
by elements
usually
given secondary
status.
This is
a piece
whose form is
articulated by
what are generally
considered
the lesser
materials
of music: texture
and timbre (in
the sense of
range, spacing
and specially
devised
effects for the piano).
This is the
essence
of Boulez's
search
for a type
of controlled
chance,
or
alia.
In
the
past,
while
reaching
for
new means
of
organiz-
ation, he relied only on musical elements to which past history
assigned
certain expectations:
pitch
focus, symmetry,
rhythmic
periodicity
and so forth.
If these elements
were to serve
as both
the
newly organized
elements
and the organizational
basis
of the
composition,
it
was possible
for
chance
to combine
these
elements
and
purposes
in
such
a
way
that
unintentional distortions
appeared.
The solution
was twofold:
first,
to
recognize
chance
as
an
adversary
and plan every
point
at which
it
might enter;
and second,
to base
the
musical structure
on a
non-expectational
element, such
as
texture.
If
chance engaging
with
structure
is seen
from this
perspective,
it
becomes
clear
that the
analyst's
job
is not to
engage
in
fruitless
pursuits
of various
routes
through
a
composition,
nor
to
endlessly
count
pitches
in
search
of even
a
changing
hierarchy
of
pitches.
His
task is
to
recognize
the tremendous
vitality
of these collections
of
pitches
as
textures
and to
begin
to
develop
a
vocabulary
suitable
first for describing,
then
for
analyzing
them.
