Few studies have been reported on the effects of music on brain biopotentials. The present investigation addresses the perception of consonant and dissonant chords by humans. Subjectively presented consonant intervals were evaluated as more harmonic and pleasant than dissonant intervals. Analysis of evoked brain activity showed that the perception of dissonant chords was accompanied by activation of the right frontal lobe, which regulates negative emotions, while consonant chords activated the left frontal area, which regulates positive emotions.
