Abstract
The aim of this study is creating a music retrieval system whose database employs “atmospheres” of music as its components. For the purpose, an atmosphere of music must be represented on computers. In the report symbols of atmospheres are represented by spectral patterns of music drawn on time -frequency planes. Because such information like harmonies of music, which have great influence on an atmosphere, is included only in raw sound data, not in MIDI nor other compressed data. The wave let transform is selected as a transform method because it is suitable for detecting fine differences of harmonies. The drawings of time-frequency planes indicate the possibility of showing atmospheres of music being represented by the method.
