New research reclassifies music from 26 different genres and subgenres into three clusters and suggests a person’s preference for a musical category is driven by personality.

Scientists from McGill University, the University of Cambridge, and Stanford Graduate School of Business collaborated on the new method of coding and categorizing music. The researchers believe the findings have important implications for industry and health professionals.

While there are a multitude of adjectives that people use to describe music, music psychologist Dr. David Greenberg and the research team mapped the musical attributes of song excerpts and then applied a statistical procedure to group them into clusters.

They discovered the musical attributes can be grouped into three categories or clusters which they labeled Arousal, Valence, and Depth.

Arousal describes intensity and energy in music; Valence describes the spectrum of emotions in music (from sad to happy); and Depth describes intellect and sophistication in music.

Investigators also found that characteristics describing music from a single genre (both rock and jazz separately) could be grouped in these same three categories.

The findings, which appear in the journal Social Psychological and Personality Science, suggest that this may be a useful alternative to grouping music into genres, which is often based on social connotations rather than the attributes of the actual music.

It also suggests that those in academia and industry (e.g. Spotify and Pandora) that are already coding music on a multitude of attributes might save time and money by coding music around these three composite categories instead.

The researchers also conducted a second study of nearly 10,000 Facebook users who indicated their preferences for 50 musical excerpts from different genres. The researchers were then able to map preferences for these three attribute categories onto five personality traits and 30 detailed personality facets.

For example, they found people who scored high on Openness to Experience preferred Depth in music, while Extraverted excitement-seekers preferred high Arousal in music.

And those who scored high on Neuroticism preferred negative emotions in music, while those who were self-assured preferred positive emotions in music. As the title from the old Kern and Hammerstein song suggests, “The Song is You.”

That is, the musical attributes that you like most reflect your personality. It also provides scientific support for what Joni Mitchell said in a 2013 interview with the CBC, “The trick is if you listen to that music and you see me, you’re not getting anything out of it. If you listen to that music and you see yourself, it will probably make you cry and you’ll learn something about yourself and now you’re getting something out of it.”

The researchers hope that this information will not only be helpful to music therapists but also for health care professions and even hospitals.

Use of music therapy has been on the rise as recent evidence has shown that the intervention helps to reduce depression and hasten recovery from surgery.

Therefore, the researchers argue that information about music preferences and personality could inform a music listening protocol after surgery to boost recovery rates.

The article is another in a series of studies that Greenberg and his team have published on music and personality. Last summer, they published an article in PLOS ONE showing that people’s musical preferences are linked to thinking styles.

And in October, they published an article in the Journal of Research in Personality, identifying the personality trait Openness to Experience as a key predictor of musical ability, even in non-musicians.

These series of studies tell us that there are close links between our personality and musical behavior that may be beyond our control and awareness.

David M. Greenberg, lead author from Cambridge University and City University of New York, said: “Genre labels are informative but we’re trying to transcend them and move in a direction that points to the detailed characteristics in music that are driving people preferences and emotional reactions.”

Greenberg added, “As a musician, I see how vast the powers of music really are, and unfortunately, many of us do not use music to its full potential. Our ultimate goal is to create science that will help enhance the experience of listening to music. We want to use this information about personality and preferences to increase the day-to-day enjoyment and peak experiences people have with music.”
