Magnetic responses to pitch-matching of musical notes in vision and in audition - comparison of well-trained musicians and non-musicians in pitch error detection

摘要

We aimed to devise a neurophysiological measure of solfege abilities. We used original unfamiliar music to present subjects, who were instructed to sight-read the score projected onto the screen and to detect infrequent performance errors in pitch. Task-related evoked magnetic fields were recorded with a 204-channel whole-head neuromagnetometer. Before trials, we evaluated musical abilities. Pitch-error evoked additive components around 200 msec in latency onto no-error responses. The correlation between those scores of behavioural abilities and the amplitudes of these differential waveforms were detected and we think the solfege ability to detect pitch errors can be evaluated neurophysiologically by this paradigm.
