This work was conceived as if it were an imaginary path proper to a compositional
act in the context of acousmatic music. Before travelling this path I dwelt
on some personal considerations about the identity of the listening space, the
perception of it and the role that loudspeaker orchestras assume in the listening
space.
On the basis of Umberto Eco's concept of the openness of a work of art and including
also examples from the past, I have considered the perception of works
of art as subjective and in the case of music, open to infinite interpretations by
the composer, the performer, the audience and the listening space. In this
sense, I have assumed that the perception of a sonic event can never be objective
even in anechoic listening spaces. Furthermore, I have stressed the importance
of the composer's encounter with the listening space in an acousmatic
situation and have considered such a phase as a moment in which the composer
encounters “spatiality”. Here, and taking my cue from Deleuze's poststructuralist
ideas which focus on the concepts of virtual and actual, I have
considered this proactive phase as a virtualization phase, since the listening
space and the combination of elements within it, offer the composer the potentials
to establish a relationship with his or her own archetypal images. In this
sense I believe that, in the context of acousmatic music, the listening space is
the incipit of the compositional act as well as the explicit since it is also the ultimate
space wherein the virtuality is actualised. Therefore I have focused,
where and when it is not possible to work in situ, on the importance of experiencing
the space itself by imagining and consulting the mapping of the listening
space.
Going forward in my imaginary path, I have written about the profound relationship
between sound material and the composer, and this I have called "the
first act", which is then followed by the phase wherein the composer judges his
or her own work. The latter, defined by Horacio Viaggione as “perceptual feed-
back loop” is a constant cycle, in which the composer judges his or her own action
and the perception of it. This path has therefore led me to the next phase,
which is the phase of structuring the material. Here, I focus on the structuring
of music according to the processes of motions. These concepts were coined
for the first time by Denis Smalley in his article "Spectromorphology" to underline
the inadequacy of traditional concepts of rhythm, which were first explored
by him from an aural perception point of view and then later by other authors
from a creative- technical and analytical one. Motion processes have been
defined by Smalley, Maurizio Giri and Alessandro Cipriani as both spectrally and
spatially applicable. Their statements however, made me consider a different
way of understanding spatial motions and, in this regard, I found Trevor Wishart's
research fascinating, who unlike the above-mentioned authors, considers
spatial motions as independent expressive music parameters, which I will deal
with in the last chapter of this text.
My intention has been therefore to shed light on this ongoing research precisely
because I believe that an awareness of the concepts of motions at a spatial
level can be useful to the acousmatic composer. This need arises from the
fact that even today, space as a compositional parameter is difficult to transcribe
and often the indications given to the interpreter are approximate. As
Alvise Vidolin rightly noted, this attitude is determined by two factors: the
need to experiment and to find new expressive possibilities linked to the identity
of a listening space, and the fact that in placing tight constraints on the
listening space the difficulty of the realisation of the work may reduce the possibilities
of its circulation.
Thanks to this research I have understood that before approaching the compositional
phase of structuring and organizing music, and in the case of acousmatic
music or in music(s) where space itself is a parameter of composition, it
is necessary to experience the listening space. I have for this reason entitled
this work "Protos Topos". In particular, "Protos Topos" from the Greek, meaning
'primary space', was chosen to emphasise that in acousmatic composition the primary role that the great Greek musicologist Aristoxenus had assigned to the
primary Tempo calling it "Protos Chronos", is no longer “Primary Tempo" but
"Primary Space". In this sense I felt the need to consider the listening space as
the Protos Topos - the theatre of the motion of sounds.
