Does music boost creativity by stirring up emotions?
Ten minutes of either cheerful or sad classical music made children more creative on a drawing test than sitting in silence, and the boost worked through how aroused the music made them feel rather than whether it made them feel good or bad.

Emotional Reactions Mediate the Effect of Music Listening on Creative Thinking: Perspective of the Arousal-and-Mood Hypothesis
Study at a glance
- Design
- Human experiment — Pre-post, three-group design: children matched into positive-music (Mozart), negative-music (Albinoni) or 10-minute silence groups; Affect Grid and TCT-DP creativity drawing test before and after; bootstrap mediation analysis
- N
- N=584 · 584 children: 198 positive music, 195 negative music, 191 silent control
- Population
- Ethnic Chinese schoolchildren aged 9-14 (grades 4-9) from four co-educational schools in Hong Kong
- Outcome
- Creativity composite from the Test for Creative Thinking-Drawing Production (0-66); arousal and pleasantness ratings on the Affect Grid as mediators

What they did
The researchers tested 584 Hong Kong schoolchildren aged 9 to 14. Children first completed a creativity drawing test and rated their feelings on the Affect Grid, a 9-by-9 grid capturing arousal (energised vs sleepy) and pleasantness. They were then placed in three groups matched on creativity, mood, age, gender and music experience. A week later one group listened for 10 minutes to an upbeat Mozart sonata, another to Albinoni's sad Adagio, and a control group sat in silence, after which everyone repeated the feelings rating and a parallel form of the drawing test.
What they found
Both music pieces raised arousal; Mozart made children feel more pleasant and Albinoni less pleasant, while the silent group did not change. Creativity scores rose significantly in both music groups but not in the silent group, and both music groups outscored controls afterwards, with no difference between happy and sad music; effects were small (partial eta squared around 0.02 for the post-test group difference). Mediation analyses showed that the rise in arousal significantly carried the music effect on creativity in both music conditions, whereas the change in pleasantness did not.
The limits
What it doesn't show
Groups were formed by matching rather than clearly described random assignment, and mood and creativity were measured at the same post-test, so the mediation analysis shows a statistical pattern rather than proof that arousal caused the creativity gain. Only classical music, only one creativity test (a drawing task), and only 10 minutes of listening were used, and effects were small. There was no relaxing, low-arousal music condition, which would be needed to confirm that arousal rather than music as such is the key ingredient. Results are from children in Hong Kong and may differ for adults or other cultures.
Key terms
- Arousal-and-mood hypothesis
- The idea that music improves later thinking not directly but by changing how energised (arousal) and how pleasant (mood) the listener feels.
- Mozart effect
- The popular claim that listening to Mozart temporarily improves spatial reasoning, which later studies found hard to replicate.
- Mediation
- When an independent variable affects an outcome through an intermediate variable, here music affecting creativity through arousal.
- Arousal vs valence
- Two dimensions of emotion: arousal is intensity or activation, valence is whether the feeling is pleasant or unpleasant.
- Dual pathway to creativity model
- A theory that activating moods boost creativity, with positive moods working via flexible thinking and negative moods via persistence.
- Manipulation check
- A measure confirming that an experimental manipulation, here music meant to induce emotions, actually had the intended effect.

Compared with sitting in silence, what did listening to Albinoni's sad Adagio do to children's creativity scores?
Common questions
Does this mean sad music is as good for creativity as happy music?
In this study, yes: both raised creativity similarly compared with silence. The authors argue that what matters is being moderately aroused, and that positive and negative moods may help creativity through different routes.
Is this evidence for the Mozart effect?
Not in the special sense. It suggests any music (or stimulus) that raises arousal might help, which is exactly why the Mozart effect was inconsistent: it depended on listeners' emotional reactions, not on Mozart.
Why is the mediation result not proof of the mechanism?
Arousal and creativity were measured at the same time after listening, and mediation models assume a causal order they cannot test. Manipulating arousal directly, for example with relaxing music, would give stronger evidence.
