 Abstract: In this article we will introduce a passive BCI system for detecting responses of the human brain on the perception of errors in music. We played cadences, sequences of chords, to subjects who are experts in music theory and actively play an classical instrument. As the expectancy is highest at the ending chord, we randomly introduced cadences with erroneous ending. In consistence with previous studies from the neurosciences we evoked an event-related potential, mainly consisting of an early right anterior negativity re ecting syntatcic error processing followed by a stronger negativity in erroneous trials at 500 ms, induced by semantic processing. We could identify single trials of these processes with a standardized, crossvalidated offline classification scheme, resulting in an accuracy of 75.7 %.
