Evoked magnetoencephalographic responses to omission of a tone in a musical scale.

摘要: The musical scale is a basis for melodies and can be simple melody by itself. present study investigated magnetoencephalographic (MEG) responses to omissions of one tone out the C major scale. preceding omitted “target” was either prolonged or repeated. In another series, after target “normal” oddball experiments, complete presented more frequently than an incomplete lacking tone, in “reverse” roles were exchanged. normal omission any produced response significantly different amplitude from standard group non-musicians, although differed depending on types omission. leading (B scale) shown elicit large when also its presence emphasized. Reverse experiments showed that repeated presentation temporarily reduced influence but could not even replace it working as “standard.” addition, auxiliary done see possible rhythmic variations.
