Abstract


Recently, music is being studied related to either its impact on the psychological interaction or cognitive process behind it. These examinations bring out music's coordination to numerous disciplines including neuroscience. A few past examinations exhibited the contrast among musicians and non-musicians regarding brain structure and brain activity. Rather than separating brain activity among musicians and nonmusicians, the current investigation exhibited diverse brain activation while musicians tuned in to music with regards to their musical experiences. The investigation intended to determine electroencephalography (EEG) microstate changes in Karawitan musicians' brains while tuning in to Gendhing Lancaran. Applying the EEG microstate investigation of 20 Karawitan musicians, the occurrence parameters were computed for four microstate classes (A, B, C, and D). Microstate properties were compared among subjects and correlated to Gendhing Lancaran perception. The present results revealed that Karawitan musicians' brains were characterized by EEG microstate classes with the increased prominence of classes A, B, and D, but decreased prominence of classes C while tuning into Gendhing Lancaran, traditional music of Java. The current investigation exhibited the diverse brain activity while musicians tuned in to music with regards to their musical experiences utilizing EEG microstate classes method analysis. Thus, our finding is the first study to identify the typical microstate EEG characteristics of the Karawitan musician's brains while tuning in to the traditional Javanese music, Gendhing Lancaran, by using the microstate segmentation method.
