Influence of Tonal Modulation in a Melodic Line on the Spectral Parameters of Human EEG

Аннотация

The influence of tonal modulation in pieces of music on the EEG parameters was studied. An EEG was recorded while subjects were listening to two series of fragments with modulations: controlled harmonic progressions and the fragments of classical musical compositions. Each series included modulations to the subdominant, the dominant, and the ascending minor sixth. The highly controlled and artistically impoverished harmonic progressions of the first series contrasted with the real music excerpts in the second series, which differed in tempo, rhythm, tessitura, duration, and style. Listening to harmonic progressions and musical fragments produced event-related synchronization in the α frequency band. Real musical fragments with modulation to the dominant generated lower synchronization in the α band as compared with other modulations. A lower decrease of synchronization in the α frequency band after listening was observed in the case of fragments of classical music compared with harmonic progressions.
