Rule-Based Emotional Coloring of Music Performance

Previously unexplored potentials offered by the KTH rule system highlight the possibility to obtain musical and emotionally different performances of the same score by hyper-articulating the performance of the score itself, i.e. by marking the structure of the composition. This new application of the KTH performance rule system is presented here. It is shown how particular combinations of performance rules, called rule palettes, can produce music performances with specific emotional coloring. In particular the principles and choices behind the design of a rule palette for angry colored performances are illustrated.
