Abstract:Music is an immensely powerful affective medium that pervades our
everyday life. With ever advancing technology, the reproduction and
application of music for emotive and information transfer purposes
has never been more prevalent. Music performance by computers is
increasingly used in computer games for enhancing the ambience of
the game environment, and there are other situations outside of
gaming where dynamic performance is more applicable than static
replay of recorded pieces.
In this seminar I will discuss a rule-based system for influencing
the perceived emotions of music. Based on empirical music
psychology, I attempt to formalise the relationship between musical
elements and their perceived emotion. I examine the modification to
structural aspects of music to allow for a graduated transition
between perceived emotive states. This mechanism is intended to
provide music reproduction systems with a finer grained control over
this affective medium; where perceived musical emotion can be
influenced with intent. This intent comes from both an external
application and the audience. Using a series of affective computing
technologies, an audienceùs response metrics and attitudes can be
incorporated to model this intent. A generative feedback loop is
setup between the external application, the influencing process and
the audienceùs response to this, which together shape the
modification of musical structure. The effectiveness of influencing
perceived musical emotion was examined in work to date, with a small
test study providing generally encouraging results.
