In this text, I explore the sonic inter-relations between space, time and timbre. The physical structure and the psycho-acoustical perception of these 3 dimensions of sound are inter-connected, and ,thus, are on a common psycho-physical continuum. When we hear transformations of timbre over time we also hear changes in the spatial dimension of the music. Different timbres resonate and reverberate in the musical space over time according to how they are transformed spectrally. Transforming a sound towards timbral simplicity (removing almost all spectral content) reduces its spatial localisation towards "point sound", whereas enriching the spectral content by increasing its noise content over time will create a more complex and indistinct spatiality as far as the localisation of the sound is concerned.
A rich and complex sound changes sonic "shape" (i.e. its resonance and reverberation in the container space) over time as the spectral content "slides" over the total timbral continuum from the simple sinewave to the complex wave. If we consider all dimensions of the sound at once, we may think of them as combining to make a spectral "harmony" of time, timbre and space. Composing with sound as such a spectral harmony means transforming at once the many dimensions of the sound over time. One can not treat the multi-dimensions of sound as completely independent "parameters" (as total serialism tried), but rather we should think of sound as a multi-dimensional, topologically varying sonic object that is in constant evolution. These sonic variations give our perception a rich and satisfying psycho-acoustical experience, especially when the composer transforms all of these dimensions at once, making for rich spectral-harmonic modulations in the space-time-timbre continuum.

In this paper I will present an analysis of Fausto Romitelli’s piece Yellow, Green and Blue aiming for the realization of the driving forces that forge the structural shape of the piece. I will primarily focus on selected concepts and ideas that could shed light on a more thorough understanding of such musical forces that not only affect the shaping of the musical form but could possibly suggest a more crucial reasoning on the understanding and listening experience of the piece. In addition to that I will address the question of syntactic coherence and sonic unity in a work of such plasticity, where discrete units such as motive, phrase, etc. are not particularly helpful terms in a sonic landscape which has to do more with sculpting of large masses of sound. F. Romitelli describes characteristically: “At the center of [his] composing lies the idea of considering sound as a material into which one plunges in order to forge its physical and perceptive characteristics: grain, thickness, porosity, luminosity, density and elasticity. Hence it is sculpture of sound, instrumental synthesis, anamorphosis, transformation of the spectral morphology, and a constant drift towards unsustainable densities, distortions and interferences, thanks also to the assistance of electro-acoustic technologies”.
The theoretical background of my analysis is intertwined with the ideas of Ms. Livia Theodorescu-Ciocanea that are thoroughly presented at her paper titled as “Timber Versus Spectralism. Ms. Theodorescu-Ciocanea describes nine different compositional tendencies in Spectral Music: Spectralism as timbral metaphor, mimetic Spectralism, Spectralism as heterophony, Spectralism and modality, Spectralism as an archetypal approach, etc. Considering such tendencies as an important point of departure, I created a theoretical - empirical model of analysis for the better comprehension and interpretation of the sounding components and gestural interconnections in Romitelli’s music.
My model comprises three hierarchical levels. The first level, “Pitch context /Harmony”, deals with the identification of pitch complexes and/or harmonic fields, intervallic schemas and the interaction of the harmonic and inharmonic spectra of the piece. The second level, “Motion/Procedure or (Musical Operations)” illustrates the means that determine the “behavior” and the shaping – pacing, formation – of the sound. The combination of the aforementioned is interpreted, in level III, as “Musical gesture”. I consider this to describe the shaping and directionality that the “sound energy” takes, in the micro and macro structural levels on the piece. Consequently, the proposed analytical discourse highlights the subtle transition from the harmonic-inharmonic elements through the way that they are formulated and shaped, leading to their sonic depiction and/or gestural formation reaching finally their structural instantiation into the music. The ultimate goal is the internal analysis and understanding of the gestural forces, their imminent effect on the sound and structure resulting in the formation and realization of larger structural levels of the piece. Each level of my analytical model will contribute to the broaden clarification of all the sonic/gestural events highlighting the reasoning behind the sonic energy that formulates the global structural shape of the piece.
