Mandi: Music has ability to affect our emotions, and it’s no secret that people often turn to music to boost their mood or to help them through a tough time. But why do we sometimes seek out sad music, even when we try to minimize sadness in our lives?

Despite our natural inclination to avoid sadness, this particular emotion has a strange and enduring appeal when expressed through art. This so-called “tragedy paradox” has puzzled philosophers for centuries. It has been postulated that the tragedy paradox arises simply because of the aesthetic appeal of gloomy tunes. Is it proof that a thing of beauty is a joy forever, or is there a more profound, biological reason for sad music making us feel better?

A recent study led by Prof. Laxmidhar Behera, Director of IIT Mandi, set out to answer the “tragedy paradox.”

Prof Behara used electroencephalography (EEG) to measure the brain activity of twenty people under different conditions. His research focused on brain regions involved in emotion and memory processing: the cingulate cortex complex and the parahippocampus.

The twenty participants had no musical training to avoid pre-programmed reactions to the selected music. EEG was measured under three states. In the first, EEG was recorded with no input – the baseline. In the second state, EEG was recorded as the participants recalled a sad experience and wrote about it – the Sad Autobiographical Recall or SAR condition. In the third, EEG was measured when they were made to listen to an Indian Classical Raga, Mishra Jogiya Raga. The music was selected by a panel of five music experts and is known for invoking Karuna Rasa (sad emotions).

EEG measures the electrical activity of the brain, commonly known as the brain waves. The researchers found that when recalling a sad experience, there is enhanced gamma wave activity while listening to sad music leads to increased alpha brain activity.

Explaining their observations, Prof. Behera said, “Listening to Mishra Jogiya Raga (sad music) appears to promote processing of emotions and memories in the brain, through a three-channel framework involving the alpha brain wave. These mechanisms include increased global and local connectivity in brain areas involved in emotion and memory processing, and increased alertness.”

The finding shows that the brain’s activity when listening to sad music is unique and distinct from both the SAR state and the baseline resting state. The coping mechanism of sad music arises from better processing of emotions and memories under the alpha state. “The coping effects are not simply due to the aesthetic appeal of the music, as previously believed, but an inherent property of sad music”, explains Ashish Gupta a PhD scholar.

While it is clear that music can affect our emotions and cognitive abilities, scientists believe that more research is needed to understand the relationship between sad music and the brain entirely. While EEG studies have provided insights into the brain response to sad music in terms of brain cortical activity, the researchers also intend to study the deeper sub-cortical areas using fMRI scans in the future.
