Perception Analysis

 
 

Principles derived from perceptual data provide an explanation of how timbre can be used as a carrier of pattern and form in music. Research in psychology on timbre has modeled its multidimensional mental representation in “timbre spaces,” which can predict many phenomena such as the degree to which instruments with different timbres playing at the same time will form separate melodic streams. Auditory scene analysis describes the principles by which sound components are perceptually grouped or separated when sounding simultaneously or playing in sequences. Listeners reports of their perceptions of musical excerpts, when combined with audio analyses, will help understand and formalize the perceptual results produced by certain orchestration techniques. The formalizations of principles will then be integrated into automatic music analysis algorithms and into computer-aided orchestration environments to make them more perceptually relevant.
