Association is a fundamental relationship between structures in a system. Hence its place in oscillation. In the terminology of complex systems theory, especially autopoiesis, I would regard association as a type of structural coupling.

Types of association as relevant to soundscape composition are

• to aspects of other soundscapes from aspects of the current
• to acousmatic and/or concrete aspects of sound streams.  For example, tonal textural or ¨pure" (read schizophonic)  acoustic association
• to other perceptual modes or fields of observation within the same soundscape.  For example, micro structural aspects extrapolated from a mesolevel prior impetus.  Think of this as spatial or temporal zooming

An example application would be to take a soundscape recording, choose a given sound or aspect of that recording, then using synthesis and further recording attempt to recreate a synthetic morphology between the holism of the soundscape recording and the specificity of the given focus.
