The Science of Sound: How Music Affects Your Brain and Emotions(2 min read)

How Music Affects the Brain

When we are exposed to music, the sounds that we process activate regions in the brain, primarily within the limbic system, which manages emotional responses. These regions, such as the amygdala and hippocampus, are associated with memory, so as we become familiar with songs our brain associates them with positive memories/feelings, promoting the release of chemicals like dopamine that increase relaxation and contribute to a feeling of pleasure. This effect by music also contributes to the motor system, explaining why people often have physical responses to music (such as dancing and keeping rhythm by tapping or clapping).

In addition to promoting positive feelings, music has been proven to inhibit negative emotions by lowering cortisol levels. Cortisol, like dopamine, is a hormone released by the brain that contributes to one’s emotions. Unlike dopamine, though, cortisol results in stress and is released during the body’s “flight or fight” response. Overexposure to it (among other stress hormones) can result in heightened blood pressure and feelings of depression or anxiety. The simple addition of music to your daily routine can result in significant changes to your mood and mental well-being.

The Emotional Power of Music

Music is deeply tied to emotions, and different types of music can evoke different feelings.

Upbeat and fast tempo music, such as rock, pop, or dance, can bring feelings of joy and energy. These types of music are directly tied to triggering the release of dopamine from the brain’s reward centers. Think of fast beats as having the ability to arouse our brain’s processing centers and motivate us for the day. On the flip side, slower and meditative music - such as smooth jazz and classical music - leads to the lowering of cortisol and thus stress levels in the body.

Songs with major chords and lively rhythms have been shown to boost mood and motivation, and have proven to help with physical exertion, like running. Similarly, songs with minor chords such as ballads or classical pieces can evoke feelings of melancholy, longing, and reflection. Lyrics that tell personal stories with emotions tied to them can also enhance this effect.

Using Music for Mental Wellness

Music has a profound impact on mental health, offering a powerful tool for relaxation, emotional expression and overall well-being. Different kinds of music can be used to support one’s mental health in various ways. For example, listening to slow, soothing music such as classical or ambient music can help to reduce stress by lowering heart rate and promoting relaxation. Many people incorporate music or natural sounds into activities like yoga to help them relax.
