Abstract: Relative desynchronization (ERD) and synchronization (ERS) of the 8-10 Hz and 10-12 Hz alpha frequency bands elicited by music were studied in ten musically untrained right-handed subjects. The subjects listened to two five-minute musical excerpts representing two different musical genres, popular and classical, presented both forward and backward. ERD/ERS of the two alpha frequency bands was examined during the first four minutes of stimulus presentation using one-minute time windows. The results demonstrated that both the 8-10 Hz and the 10-12 Hz frequency band exhibited reactivity to musical stimuli. The responses of the 8-10 Hz and 10-12 Hz alpha frequency bands were dissimilar, dynamic and dependent on both time and stimulation type. The dynamics of these changes over time may explain some discrepancies in earlier EEG studies during listening to music.
