Multidimensional scaling of emotional responses to music: The effect of musical expertise and of the duration of the excerpts

Musically trained and untrained listeners were required to listen to 27 musical excerpts and to group those that conveyed a similar emotional meaning (Experiment 1). The groupings were transformed into a matrix of emotional dissimilarity that was analysed through multidimensional scaling methods (MDS). A 3-dimensional space was found to provide a good fit of the data, with arousal and emotional valence as the primary dimensions. Experiments 2 and 3 confirmed the consistency of this 3-dimensional space using excerpts of only I second duration. The overall findings indicate that emotional responses to music are very stable within and between participants, and are weakly influenced by musical expertise and excerpt duration. These findings are discussed in light of a cognitive account of musical emotion.
