ABSTRACT
This chapter presents research that might have been or actually has been undertaken in the environment of music schools at university level, working with live musicians, and addresses either performance or perception of live performance issues. It focuses on three various stages of the musical message: cognitive, acoustic, and electroacoustic. The chapter illustrates briefly the results of some investigations that were conducted in a music-acoustics laboratory situated within an academy of music. The research concerned the perception of pitch, and may be classified as psychoacoustics of music. The research was performed with the indirect method of measuring pitch strength. Very important problem concerns the pitch matchings that fell outside the concentration region of the main frequency. Ultimately, a theory of multidimensional structure of musical pitch was selected on the basis of psychological facts – monochromatic distribution of pitch-matching frequencies.
