The brain activities of the perception of musical cadence

Cadence is a typical structure of a tonal closure. To investigate the recognition process of cadence, we composed a song with two types of cadence, Dominant-Tonic, "chord sequence V-I". To analyze perception of cadence, we have presented to the songs to thirteen musicians and analyzed their behavior performance and brain activities by EEG measurement. As a result, during presentation of chord I of "chord sequence V-I", a sense of closure was elicited. In addition, the strength of sense of closure depended on the cadence structure type. We have also detected the brain activities related to the perception of a sense of closure, during presentation of chord V in "chord sequence V-I" Type I with stronger closure, and chord I in "chord sequence V-I" Type II with weaker closure. These activities were speculated to activities related to the initial music-syntactic processing and processing of musical semantics.
