The thesis analyses MIDI recordings of a performance of a wind
instrument player and deduces conclusions regarding the level
of imperfection that is characteristic for an interpretation
of a musical score. It consequently considers options of
reconstruction of such imperfection using
computer-understandable transcription of the given score (i.e.
also MIDI data). The thesis compares present methods and means
of humanization which use only limited possibilities of
generating parameter deviations using simple pseudorandomness
and, based on the analysis of the input MIDI material, outlines
or directly develops their possible improvements.
