Music and awe: complex emotions evoked by tonal dissonance

A groundbreaking study published in Frontiers in Psychology has illuminated the intricate relationship between musical dissonance and the profound emotion of awe, challenging long-held assumptions that dissonance is merely unpleasant. The research, conducted by Sara Wilson, R.F. Braaten, and S.J. Coluzzi at Colgate University, reveals that while consonant music tends to elicit pleasure, its dissonant counterpart can evoke significantly stronger feelings of power and awe, particularly among musically experienced individuals. This nuanced understanding of music’s emotional impact opens new avenues for research in psychology, music theory, and even therapeutic applications.

The Sound of Awe: Dissonance as a Catalyst

The study, which involved 50 participants, systematically explored how consonant and dissonant musical excerpts influenced experiences of pleasure, power, and awe. The findings suggest a complex interplay between harmonic tension and emotional response. Consonant harmonies, characterized by their smooth and stable qualities, were predictably linked to higher ratings of pleasure. However, dissonant harmonies, often perceived as creating tension and roughness, surprisingly emerged as potent triggers for feelings of power and awe.

This effect, however, was not linear. The researchers observed a distinct "tipping point" where extreme dissonance, such as that found in highly chromatic or atonal compositions, led to a decline in both pleasure and power ratings. This suggests that while controlled dissonance can amplify emotional intensity, its complete absence of tonal grounding or familiar harmonic structures may overwhelm listeners, diminishing engagement.

A key revelation from the study is the specific dimensions of awe that dissonance appears to enhance. Participants exposed to more dissonant music reported significantly heightened experiences of altered time perception, self-diminishment, perceived vastness, physical sensations (like chills), and a greater need for accommodation to process the overwhelming experience. These findings align with broader psychological conceptualizations of awe as a state that transcends mere positive affect, involving a sense of being humbled by something larger than oneself.

The Role of Musical Experience

A significant moderator in this relationship was the participants’ level of musical experience. Individuals with more extensive musical backgrounds consistently derived greater pleasure, power, and awe from dissonant music compared to their less experienced counterparts. This suggests that musical training and engagement equip listeners with the cognitive frameworks and perceptual sensitivities to appreciate and be moved by harmonic complexity.

The study also explored the personality trait of "openness to experience," which is known to correlate with a propensity for awe. While openness to experience showed a significant positive correlation with musical experience, musical experience itself emerged as a more potent predictor of responses to dissonance in this particular study. The researchers hypothesize that the deliberate recruitment of participants with varied musical backgrounds may have amplified the effect of musicality while the generally high levels of openness in the student population might have masked its individual predictive power.

Challenging Conventional Wisdom: Dissonance Beyond Unpleasantness

Historically, dissonance in music has often been equated with unpleasantness, a concept rooted in acoustic properties like "roughness" and the brain’s initial neural responses to complex frequency ratios. However, this study challenges this simplistic view by demonstrating that dissonance can be a powerful vehicle for complex and intense emotional experiences, including awe. This aligns with a growing body of research that recognizes the aesthetic and emotional value of tension and complexity in art, moving beyond a purely pleasure-based model of aesthetic appreciation.

The findings echo historical observations by music theorists like Zarlino in the 16th century, who noted that while dissonances might not be pleasing in isolation, their skillful placement could lead to even greater pleasure and delight when resolved. This underscores the long-recognized power of tension and release in musical composition.

Methodological Approach and Implications

The research employed a multi-faceted approach, utilizing curated playlists of consonant and dissonant musical excerpts, validated by independent raters. Participants then rated their experiences of pleasure and power on Likert scales after each excerpt, and their overall awe experience using the comprehensive Awe Experience Scale (AWE-S). This scale assesses six dimensions of awe: altered time perception, self-diminishment, connectedness, perceived vastness, physical sensations, and need for accommodation.

The implications of this research are far-reaching. Understanding how dissonance can evoke awe might inform the development of music-based therapeutic interventions. For instance, carefully selected dissonant music could potentially be used to facilitate emotional processing, promote mindfulness, or even induce states of transcendence, particularly for individuals struggling with emotional regulation or seeking novel forms of catharsis.

Furthermore, the study contributes to a deeper understanding of the psychological underpinnings of aesthetic experience. By highlighting the non-linear relationship between positive affect and emotional intensity, it encourages a more sophisticated appreciation of art’s capacity to move us through a range of emotions, not solely those that are conventionally pleasant.

Future Directions and Limitations

While this study offers significant insights, the researchers acknowledge several limitations. The subjective nature of music perception and categorization, the potential influence of other musical elements beyond dissonance (such as tempo, timbre, and familiarity), and the demographic skew towards young, Western participants are noted. Future research endeavors are encouraged to explore these aspects further, including cross-cultural investigations into dissonance perception and the neurological mechanisms underlying music-evoked awe.

The study’s authors suggest that the "tipping point" observed in dissonance levels warrants further investigation. The decline in pleasure and power at the highest levels of dissonance, particularly in atonal music, suggests a potential human preference for "goal-directed" tension that is absent when tonal grounding is completely relinquished. This could be explored through neuroscientific studies examining brain activity during exposure to varying degrees of dissonance.

In conclusion, this research provides compelling evidence that tonal dissonance is not merely an unpleasant aspect of music but a potent catalyst for complex emotional experiences, most notably awe. As our understanding of music’s profound impact on the human psyche continues to evolve, this study offers a critical piece of the puzzle, challenging us to reconsider the emotional landscapes that music can evoke and the sophisticated ways in which our brains and bodies respond to harmonic complexity.
