Abstract :
Studies of proficiency estimation for musical performance
have been intensively conducted in the field of
performance science.In most of the studies, feature
parameters are calculated from sound of performance to
estimate performance proficiency. However, most cases in
such studies estimated only proficiency score, not for
expressiveness or technique, that are considered as
important for proficiency estimation. Therefore, this report
tries to clarify a relation between effective acoustic
parameters and scores of proficiency, expression or
technique on violin performance. Moreover, most important
parameters of each scores are discussed. Firstly, five
professional violin players gave scores for proficiency,
expressiveness and technique to 100 performances for
simple major scale starting from 261Hz or C3 with vibrato.
Then, a set of 98 parameters are calculated from the 100
performances. By using the parameters, scores for
proficiency, expressiveness, and technique are estimated
using liner regression with relative weights for each
parameter, so that we confirmed the most effective
parameters. As a result, most important parameters on each
score are: FM vibrato parameters on proficiency, strength on
attack for each note on expressiveness, and smoothness on
consecutive two notes on technique. At the conference,
authors will explain this result in detail on their presentation.
