BERLIN, Germany — Listening to sad music while feeling down may seem like it could make matters worse, but it actually elicits positive emotions, according to a recent study. Sad music offers a number of emotional rewards to listeners, including some that happy music doesn’t provide, according to researchers from the Free University of Berlin. Liila Taruffi and Stefan Koelsch asked 722 people about how they felt while listening to sad music and published the results in the journal PLOS One.
