In preparation for what ended up being a big night for Adele, the WSJ posted a story about why tear-jerkers, as a lot of her songs are, are so effective in bringing out emotion… and why we can’t stop listening.
An appoggiatura is a type of ornamental note that clashes with the melody just enough to create a dissonant sound. “This generates tension in the listener,” said Martin Guhn, a psychologist at the University of British Columbia who co-wrote a 2007 study on the subject. “When the notes return to the anticipated melody, the tension resolves, and it feels good.”
Chills often descend on listeners at these moments of resolution. When several appoggiaturas occur next to each other in a melody, it generates a cycle of tension and release. This provokes an even stronger reaction, and that is when the tears start to flow.
…
When the music suddenly breaks from its expected pattern, our sympathetic nervous system goes on high alert; our hearts race and we start to sweat. Depending on the context, we interpret this state of arousal as positive or negative, happy or sad.
If [Adele’s] “Someone Like You” produces such intense sadness in listeners, why is it so popular? Last year, Robert Zatorre and his team of neuroscientists at McGill University reported that emotionally intense music releases dopamine in the pleasure and reward centers of the brain, similar to the effects of food, sex and drugs. This makes us feel good and motivates us to repeat the behavior.
The story has plenty of embedded clips that demonstrate this.
