There are songs that can transport us to memorable moments from our past, especially from our adolescence. Those memories are often vivid, conjuring up intense feelings about a first love, a broken heart, a shared experience with friends. Music, even just a few notes, has a way of unlocking forgotten events and relationships, creating a soundtrack for our lives.

Our guest this week is Elizabeth Margulis, director of The Music Cognition Lab at Princeton University. She joins us to discuss why music can transport us and connect us to others, how different cultures shape our taste in music, and how melodies affect our mood. We’ll also talk about why some tunes can get stuck in our head, why repetition is central to music, where music is stored in the brain, and how music can unlock language for people with aphasia.
