Harmony wants to sit in the front - Different Brain Responses to Violations in Chord Progressions
2009
Deviations from auditory regularities elicit electric potentials distributed over the frontal regions of the scalp. The mismatch negativity (MMN) is elicited by change in repetitive auditory input, whereas the early right anterior negativity (ERAN) is elicited when sounds deviate from a hierarchically organized musical regularity. In this study we wished to disentangle the functional roles of these two brain processes associated with the detection of sequential vs. hierarchical musical violations by studying the localization of their neural generators. Subjects listened to musical cadences constituted by seven chords, each containing either harmonically congruous chords, harmonically incong…
A Coupled Oscillator Model of Interactive Tapping
2009
Background: Synchronization in music has been a popular experimental basis for studying social interactions, as musicians are required to synchronize to each other’s beats and integrate abstract social information in order to coordinate their actions as part of a non-verbal communication process. A finger-tapping paradigm has been used in studies of sensorimotor synchronization as well as coordination dynamics within and between people (Repp 2005). Recent models of tapping dynamics have included two error-correction mechanisms: phase and period correction (Repp & Keller). They have generally been linear models, which are oversimplifications of these dynamics. Aims: To model the dynamics cap…
