Popular music, for example, was brought out of obscurity
and into the concert hall mainly through cabaret, a
variety of caf’ conc’ (cafe concert), which gave popular
music a stable outlet from the mid–nineteenth century
onward. Whether we consider the caf’ conc’ of Europe or
club performances in the United States, the genealogy of
the pop star is primarily connected to the oppressed and
to those racially or economically discriminated against.
Since popular music could not depend on support from the
rich and sophisticated as classical music did, it relied
on ordinary men and women and their purchasing power.
Because of the popular
song’s intrinsic simplicity and its appeal to the
artistically unsophisticated, a new market for musical
representation of unprecedented dimensions and power was
created. The pop star not only embodied the musical
tastes of the underprivileged but also became a symbol
of social and economic success; he or she became one of
the groups who "made it." Ironically, the symbol of the
pop star simultaneously served another role, that of
social pacifier: frustration – helplessness and
powerlessness – could be infinitely rationalized and
sublimated through the image of a socially successful
equal.
If the Classical period of Western art music liberated
the musician from his preordained social role in the
hierarchical world of feudalism, the Romantic era
strengthened this process further: the musician’s role
as an individualistic and original spirit which had been
a new possibility, became an exigency. It is mainly from
this era that the image of a suffering, misunderstood
genius comes. In other words, the totality of the
individual became the exclusive focus of music. The same
process that had served to liberate the musician became
an instrument of his alienation. The logic of this
process can be seen in the historical transformation of
the musician’s role and of musical practices in the
social context and in the genealogy of musical processes
and structures. Several distinct lines of development
follow from the Romantic period to today: an increasing
complexity of the elements and overall form of music; an
integration of spatially (diverse ethnic sources) and
temporally (diverse periods) different musical worlds; a
replacement of natural frames of reference with
artificial or scientific ones; and an increasing
elasticity of musical expression.
The rhythmic profile was refined horizontally, to
include diverse subdivisions, and vertically, to include
complex superpositions: the beat was no longer the
carrier of the rhythmic pulse but only a reference in
the general flow. Melody and harmony followed the
emancipation of dissonance in horizontal and vertical
aspects. The natural hierarchy of the overtone series
was replaced by an artificial, relative universe (from
drone to modal to major-minor to extended tonal to
serial). Similarly, there was a shift from cyclical and
periodic forms to aperiodic and nonarchetypal forms.
Profound psychological changes took place at the same
time: if the archetypal form and overtone-based natural
hierarchy gave a confining but secure place to the
premodern individual, the newly constructed relative
universe gave him a limitless but isolating freedom.
This freedom resulted primarily from a heroic effort of
the intellect, which subsequently became a hallmark of
twentieth century music.
Historically speaking, every period’s particular
psychosocial reality is manifested in the idiosyncrasies
of its musical structures and processes: a strong
rhythmic pulse coupled with the pentatonic and modal
systems of tribal (folk) music reflected a collective,
rather than an individual, consciousness; the tonal
system combined with the unified but limited rhythmic
profile of Western art music before the twentieth
century reflected an increasingly individualistic
emotional and intellectual reality; the atonal,
aperiodic, free-pulsating music of the contemporary era
points to two extremes: at one end, a highly refined but
narrowly focused individual consciousness and, at the
other, a quasi-scientific, ego-free and thus impersonal,
consciousness.

PART II
Orientations
If the nineteenth century planted the seeds of spatial and
temporal expansion, the twentieth century brought this potentiality to
full fruition. A multitude of orientations appeared, which could be
roughly classified as follows:
• The influence of ethnic music
• Historical awareness and conservation
• Scientific development and experimentation
• The explosion of popular idioms and development of communications
media.
The Influence of Ethnic Music
Ethnic music has in general been the source of composed music. Although
diverse levels of stylization and abstraction of folk elements have
characterized different periods, the fundamentals of musical style can
usually be traced to ethnic music. At its most particular, folk music is
a tradition limited to a certain region and people; at its most
universal, a powerful source for synthesis in an international context.
West European folk music (and to a lesser extent, that of the
Mediterranean region) has been the principal source for Western art
music. The history of Western art music is characterized by a process of
refinement and complexification, which despite independence and
isolation, has often undergone profound transformation through the
influence of folk music. One could even argue that most of music history
oscillates between the particularity of the folk element and the
universality of its stylization.
Although the influence of folk music has been substantial throughout
history, it was not until the beginning of the twentieth century that
the great syntheses of folk and art music took place: I refer primarily
to Igor Stravinsky, Béla Bartók, Manuel de Falla, Maurice Ohana, Olivier
Messiaen, and others in contemporary classical music, as well as to a
large number of blues and jazz musicians. Debussy’s music clearly was
influenced by oriental music; his use of quartal harmony, pentatonicism,
and modality refer to Indonesian gamelan and Chinese folk music.
Messiaen’s Promethean synthesis of Indian raag and occidental systems
inspired many later developments, although none that match the strength
and coherence of his creation. As Stravinsky and Bartók uncovered the
powerful rhythmic and melodic structures of east European folk music,
such jazz greats as Thelonius Monk, Miles Davis, Don Ellis, John
Coltrane, and others accomplished various syntheses of African and other
kinds of music, while reintroducing the art of improvisation into the
creative process.
Although improvisation was an integral part of musical practices from
folk to Renaissance to Baroque, as role specialization increased,
improvisation gradually lost its place. According to Piaget’s Psychology
of Intelligence, irreversible processes such as perception and
semireversible processes such as sensorimotor systems belong to older
psychophysical layers of consciousness while reversible processes such
as operational thinking belong to newer layers. It is not surprising
therefore, that most folk music relies strongly on improvisational
practices, especially since such music is based mostly on oral, rather
than written, tradition. Both irreversible and reversible processes play
major roles in both improvised and composed music. A fundamental
difference, however, is that while improvisation occurs irreversibly,
the compositional process has the possibility of reversibility. In other
words, composition is "frozen in time," permitting control of the
horizontal, vertical, and overall formal aspects of a piece, while
improvisation relies mainly on the inspiration and chance of the moment.
Yet both improvisation and composition are
based on unified and elaborate musical systems.
The twentieth century, therefore, reintroduced the vitality of the folk
idiom and improvisational practice into musical reality. Psychologically
speaking, this reintroduction caused an eruption of older layers of
consciousness (magical and mythical) from beneath carefully guarded
rational consciousness. A whole generation of composers and improvisers
has been experimenting with the integration of these musical universes
in various practices such as aleatoric operations, free jazz, and
others.
