Assessment methodologyAssessment methodology Use emotional descriptions to select and
manipulate music with appropriate musical features
Play an emotional playlist Identify emotions through the analysis of
psychophysiological and self-report measures

ConclusionConclusion
Design a computational model of music production grounded on affective and psychophysiological foundations
Validate the model with users to promote a reliable expression and induction of emotions by using music
System can be applied in areas that intend to produce music given an emotional input
Music Therapy, soundtracks for arts, movies, dance, theater, virtual environments, computer games, etc.
