It sounds so appealing: using music to strengthen our memory. A new study in the Journal of Neuroscience (Clark & Leal, 2025) tested this idea by examining how music influences memory when played shortly after learning. The British Psychological Society also covered the paper, rightly stressing the need for caution.

What the Study Actually Found

In the experiment, students learned a set of objects. Then they listened for ten minutes to either classical music designed to evoke positive or negative emotions, familiar or unfamiliar sounds, or neutral sounds such as white noise or a crackling fire. Afterwards, their memory was tested for both the gist (general recognition) and the details (acceptable discrimination). The key finding was that there were no differences between the music and control groups.

Only when the researchers examined individual differences in emotional arousal did subtle patterns emerge. A moderate increase in arousal was associated with better memory for details but poorer recall of the gist. Substantial increases or slight decreases showed the opposite effect: gist memory improved, detail memory suffered.

Why Alzheimer’s Often Gets Mentioned

Why, then, do people immediately think of Alzheimer’s disease when they hear such findings? Music can evoke strong emotions and autobiographical memories, even in people with dementia who struggle with other forms of recall. This makes music an intriguing candidate for therapy. The new study suggests that music can modulate arousal in ways that shape memory encoding. It is therefore understandable that researchers explore its potential for conditions such as Alzheimer’s. But the results also show the effect is far from uniform – and sometimes even contradictory.

So what should we take away? Past meta-analyses have already shown little evidence for the broad transfer of skills from music to general cognitive abilities or memory, something we discussed extensively in our second Urban Myths book. This new study confirms that caution is warranted. Music can influence mood and sometimes nudge memory in one direction or another, but it is not a magic shortcut to a better memory.

Perhaps that is precisely where its real value lies: music is beneficial for our well-being, motivation, and mood. That alone is important. But anyone promising that listening to Mozart for fifteen minutes will sharpen your memory is selling hope rather than hard science.
