This dissertation comprises a collection of works that address aspects of sound

occupying space. Those aspects refer to inner components of timbre and rhythm and

how these may influence the perception and projection of sound. These works also

address the interaction of physical or virtual spaces and spatial attributes of sound in

regard to rhythm and timbre. The composition of timbres serves as fundamental base

for the musical material contained in the works, using sound synthesis and extended

techniques as a paradigm for articulation and instrumentation of sound in vertical and

horizontal layers. Rhythm is not only a parameter that articulates time; it may also be

the parameter that articulates musical material. The relationships of timbre and rhythm

serve as expressive substance for the elaboration of immersive soundscapes that are

molded by time and memory.
