A research on understanding of piano players’ control of performance behavior in brushing up processes of music piece using Near-infrared spectroscopy

In this paper, we are studying about the method in which we could catch the relationship between players’ perception of sonic field environment and the following control of playing behavior characteristically. Based on the above way of thinking, we made some measuring experiments on some actual performances in brushing up processes, and analyzed and considered about the difference between experimental results from the view point of the perception and behavior control. Already, it has been shown that measuring the change in frontal lobe brain blood flow using Near-infrared spectroscopy (NIRS) Brain-measuring-apparatus and comparative-analyzing the measured data was different by a variety of psychological conditions. In this paper, adopting the above method, we measured subjects’ frontal lobe brain blood flow on two actual performance of the early stage “performance of playing at sight” and the final stage “performance of automated levels” in proficiency-process. After some supplementary interviewing to subjects about their measured practices, we analyzed about control of performance behaviors in some sonic environment. The analysed results show that we could measure two each status of “the perception and behavior control” on actual performance of “performance of playing at sight” and “performance of automated levels” in proficiency-process characteristically.
