Consonant chords stimulate higher EEG gamma activity than dissonant chords
Research highlights
▶ Consonant chords have coherent auditory properties by physical characteristics. ▶ Induced gamma band are more increased by consonant chords than dissonant chords. ▶ Gamma bands may reflect auditory coherent percept.

2022, Physics of Life ReviewsCitation Excerpt :Furthermore, subjective factors, such as attention, might also affect the N1 response. Several neuroimaging and electrophysiological studies have provided evidence of a hemispheric specialization in C/D perception, showing that consonant sounds are primarily processed in the right hemisphere, while dissonant sounds are processed in the left hemisphere ([151,164,168,170,181,182]). In contrast, other findings suggest that the right hemisphere exhibits higher sensitivity toward dissonant sounds (e.g., [74,139]).
Musicians and non-musicians' different reliance of features in consonance perception: A behavioral and ERP study
2014, Clinical NeurophysiologyCitation Excerpt :Similarly, Shahin et al. (2003) had skilled musicians (violinists and pianists) and non-musician controls passively listen to violin tones, piano tones, and pure tones matched for fundamental frequencies, and the musician group showed the largest N1c and P2 responses to their preferred types of tonal stimuli (violin tones for violinists and piano tones for pianists) compared with non-musicians. Similar results from musical training paradigms, as well as from gamma/beta/theta band activity during various chords, have also been reported (Park et al., 2011; Shahin et al., 2008, 2010). Using functional magnetic resonance imaging (fMRI), Minati et al. (2009) found that musicians had larger hemodynamic responses in the inferior and middle frontal gyri, premotor cortex, and inferior parietal lobule when comparing consonant to dissonant chords during four-tone chords.
