From Nature.com/news http://www.nature.com/news/2007/070409/full/070409-13.html According to the article, there has never been a systematic review of the literature supporting the so-called Mozart Effect until now. The report concluded that "Passively listening to Mozart — or indeed any other music you enjoy — does not make you smarter. But more studies should be done to find out whether music lessons could raise your child's IQ in the long term..." I think it was mostly wishful thinking anyway, part of the cult of Mozart. However I do think that Mozart can have a marked effect on one's mood. Does for me anyway.
