Abstract
Research on musical aesthetic patterns on different decades of the second part of the last twentieth century allowed specific studies based on frequency and amplitude data. This approach is carried out mainly to locate musical instruments and their relations inside the stereo image (the traditional audio virtual space), so a bidimensional map development was determined as a key part for finding spatial distribution patterns on different periods of stereo music masters -to be able to characterize timbral aesthetics from a measured perspective-. This article presents the concepts, methodology and the analysis performed, a well all their results. Hence, a new approach of musical sound sources conceptualization inside the stereo image is presented, where they are either spectral or dynamic component constellations. Additionally, this concept and approach could apply to any kind of sound sources inside a recorded signa
