SADNESS is an emotion we usually try to avoid. So why do we choose to listen to sad music?

Musicologists and philosophers have wondered about this. Sad music can induce intense emotions, yet the type of sadness evoked by music also seems pleasing in its own way. Why? Aristotle famously suggested the idea of catharsis: that by overwhelming us with an undesirable emotion, music (or drama) somehow purges us of it.

But what if, despite their apparent similarity, sadness in the realm of artistic appreciation is not the same thing as sadness in everyday life?

In a study published this summer in the journal Frontiers in Psychology, my colleagues and I explored the idea that “musical emotion” encompasses both the felt emotion that the music induces in the listener and the perceived emotion that the listener judges the music to express. By isolating these two overlapping sets of emotions and observing how they related to each other, we hoped to gain a better understanding of sad music.

Forty-four people served as participants in our experiment. We asked them to listen to one of three musical excerpts of approximately 30 seconds each. The excerpts were from Mikhail Glinka’s “La Séparation” (F minor), Felix Blumenfeld’s “Sur Mer” (G minor) and Enrique Granados’s “Allegro de Concierto” (C sharp major, though the excerpt was in G major, which we transposed to G minor).
