Estimation of Brain Activities in Response to Major and Minor Triads and Scales by FMRI

Abstract

Abstract-Brain activities to major and minor chords and to major and minor scales were measured by sparse scanning fMRI. Areas activated by major and minor chords and scales were examined. Some of them are known to be related to emotion, motivation, arousal or reward. In general, minor stimuli activated lager areas of brain regions than major stimuli. Interestingly, scale stimuli seemed not to have activated regions related to emotion processing so much of the chords stimuli.
