Romantic couples tend to share far more similar musical tastes than their personality traits or personal values, a three-study project suggests, with this musical alignment linked to modestly higher relationship tenderness. The research, drawing on 309 pairs from Germany and Austria, indicates that music preferences may outshine personality in predicting how connected partners feel.
Musical preferences go beyond entertainment; they reflect a person’s psychological makeup, emotional regulation and personal identity, the researchers say. Music is routinely used as a social signal to communicate who someone is, and the studies position taste in artists and genres as a meaningful social attribute within relationships.
Past work has shown music to be a common topic of conversation when young adults meet and to function as a shortcut to judging personality. Other findings have suggested that shared tastes can boost attraction by signalling similar underlying values. At the same time, studies mapping how partners match across traits have shown broad similarity across many behavioural dimensions, while links to relationship happiness remain inconsistent.
To bridge these strands, Julia Vigl and Marcel Zentner of the Music, Emotion, Assessment, and Personality Lab at the University of Innsbruck designed a project to test whether real couples share musical tastes more than they share personality traits or values, and whether a musical match predicts how happy they are in their relationship. “We know quite a lot about similarity between romantic partners in personality, values, and other personal characteristics, but much less about similarity in aesthetic preferences,” Zentner said, emphasising the focus on how people express themselves through music.
He added: “Several years ago, I conducted a side-project that suggested an association between similarity in music preferences and relationship satisfaction. Julia and I then decided to take up this question again in a more rigorous way.”
The researchers recruited couples who completed online questionnaires rating their musical genres, listing their favourite and least-favourite artists, and assessing their personality traits, personal values and relationship satisfaction. Artists were categorised using online social tags, allowing the team to measure overlap even when partners named different bands. Participants also provided data on their musical backgrounds and listening habits.
To determine whether the observed similarities exceeded what random chance would produce, the real couples were compared with pseudo-couples formed by randomly pairing participants from the dataset. This allowed the scientists to separate romance‑driven similarity from broader cultural trends.
The first study involved 99 relatively young couples. The findings showed real couples were far more alike in their music preferences than the random pairings, and this musical overlap exceeded similarity in personality traits or personal values. Matching on personality and values showed no reliable link to relationship quality, whereas sharing favourite artists was associated with a modest increase in tenderness between partners.
The second study expanded the sample to 99 couples with a wider age range and longer relationships. Using slightly different measures of personality and values, the researchers again found that couples were more concordant in musical tastes than in personality. In this older group, there was again a small positive association between sharing favourite artists and tenderness, though there was no overarching boost to relationship satisfaction.
In the third study, 111 couples were examined and researchers added measures of love components such as intimacy, passion and commitment. They also considered whether both partners played instruments or spent substantial time listening to music. Even when accounting for musical training, the couples showed unusually high similarity in their musical tastes. In this cohort, sharing least-favourite artists correlated with a slight rise in feelings of love and relationship satisfaction.
Pooling all three studies, the researchers confirmed that romantic partners are highly similar in their music preferences, far more than in personality or values. “Romantic partners tend to have significantly more similar music preferences than would be expected by chance,” Zentner noted. “We were surprised by how consistently the effect emerged across our studies, and by the fact that similarity in music preferences was substantially greater than similarity in personality and values.”
Yet the association between music similarity and relationship happiness remains small. “The difference between couples and randomly paired individuals was fairly substantial for music preferences,” Zentner said. “The association between music similarity and relationship quality, however, was smaller, so shared musical taste is not what makes or breaks relationships but it seems to help a little.”
The authors also warned that the study sample was itself biased towards highly satisfied couples, a common limitation in relationship research. The findings are correlational, they emphasised, and do not establish whether shared musical preferences cause better relationship quality, whether partners become more similar over time, or whether people with similar tastes simply choose one another. “Our studies were correlational, so they cannot tell us whether shared musical preferences contribute to relationship quality, whether partners become more similar over time, or whether similar people are simply more likely to choose one another,” Zentner pointed out. “Nor do the findings imply that couples with different musical tastes are incompatible.”
Looking ahead, the researchers plan longer-term work to explore how musical taste similarity emerges. Zentner spoke of online dating experiments and an 18-month longitudinal study of early couples, aimed at understanding whether people prefer potential partners who share their music tastes and whether couples’ tastes converge over time. “We would like to understand how similarity in musical preferences between romantic partners emerges in the first place,” he explained. “Do people generally prefer potential partners who share their music tastes, and are couples already similar at the beginning of a relationship, or do their preferences become more similar over time?”
In a final note, Zentner confirmed ongoing work to re-examine whether sharing music preferences relates to relationship satisfaction, outlining plans for a dating experiment and the longitudinal study “this month.”
The study, Harmonies of Taste: Shared Music Preferences and Compatibility in Romantic Relationships, was authored by Julia Vigl, Felix Lene Ihrig, Miriam Greif, and Marcel Zentner.
