Combinations of performance rules and of their parameters can
be used for synthesizing interpretations that differ in emotional quality. Performances were synthesized so as
to elicit listeners' associations to six different emotions (fear, anger, happiness, sadness, tenderness, and solemnity).
The rules and their parameters were selected so as to match previous findings about emotional aspects of music
performance, conducted by Alf Gabrielsson & Patrik Juslin, Uppsala. The rules produced variations of the performance
timing and dynamics with respect to a nominal performance. In a forced-choice listening test 20 listeners were
asked to classify the performances with respect to emotions. The results showed that the listeners, with very few
exceptions, recognized the intended emotions correctly. This shows that a proper selection of rules and rule parameters
in Director Musices can indeed produce a wide variety of meaningful, emotional performances, even extending the
scope of the original rule definition
