You must be aware that overall listening to music can improve one's mood, reduce stress, and promote general well being. Having said that, a lot of people find it delightful and calming to listen to classical music, especially works by Mozart. Listening to Mozart's music can be enjoyable but also boost your brain functioning. If you like the catchy tune, there's no harm in listening to it.
The "Mozart effect," which is the theory that listening to Mozart helps improve brain function, became well-known in the 1990s. The idea originated from a 1993 study by Rauscher, Shaw, and Ky that found college students' spatial-temporal reasoning abilities temporarily improved when they listened to Mozart's sonata for two pianos in D major for roughly ten minutes.
