Abstract: It has been reported that if music is realized as
nominally described by the score, a musically unacceptable
performancee merges. Music interpretationi s necessary to
generatea musically acceptablep erformanceW. e have been
constructing a rule-based music interpretation system that
generates sophisticated performance from a printed music
score. The whole performanced ata are given by the product
of expression of each dynamic mark explicitly drawn in the
score and expression of analyzed motives. This paper
describes the function of learning how to play music, which
is the most importantp rocess in music interpretationT. he
target to be learned are expression rules and grouping strategy;
expression rules are used in order to convert dynamic marks
and motives into concrete performance data, and grouping
strategy is used in order to extract motives from note sequence.
They are learned from the given virtuoso performanc
