Zampronha %T Paisagem Sonora: uma proposta de an?lise %X This paper discuss the use of environmental sounds in musical composition, specially in the so-called Soundscape music. The use of such sounds in compositions created with technological support after the 60?s have started a controversial discussion on the musical syntax that such sounds can generate. The environmental sounds also raised important debates related to theories of auditory perception. Related to this point we present the processes of listening based on the ecological approach to auditory perception, which comes from J. J. Gibson?s theory of direct perception. This theory is taken as base to a new approach to environmental sonic materials and its insertion in the compositional processes. Our goal is to raise the issues that had lead to all those problems, and to briefly expose the theory of direct perception of J.J. Gibson as well. We conclude showing a possibility to use the notions of the ecological approach to perception as alternative analytic tools for soundscape music. %D 2003 %K Soundscape; Ecologic Perception; Musical Analysis. %L cogprints3000
