Illustration 2 shows the tones used as part of a demonstration on stream segregation by Bregman and Ahad based on Bregmans own earlier works. The demonstration consisted of three high and three low notes played in a repeating pattern. They note that when the cycle is played slowly one would easily be able to hear the relationship between the tones as an alternation between them, indicated by dashed lines. However if the same pattern of tones is played back fast the alternation can no longer be heard, instead it is replaced by two separate streams of high and low notes playing together. According to Bregman this demonstration showed that the stream segregation effect is reliant in part on the speed at which the tones are played(Bregman & Ahad., 1995).…show more content…
Stream segregation in music cognition In music cognition, stream segregation is known as melodic fission(Dowling., 1973). As stream segregation is all about sound, it is no surprise that the concept is studied vigorously in in its application to music. The research performed has shown that, asides from a faster sequence of tones, there are multiple ways to separate auditory streams. Timbre…show more content…
Amplitude Different amplitudes in a group of pitches has shown to lead to stream segregation. The bigger the amplitude difference in a set of tones are the higher the likelihood of stream segregation are to occur. Experiments has shown that with this type of segregation the high amplitude will be perceived as interrupting the low amplitude stream(Noorde., 1975).
