Hello, I would like to submit this link for an article which a friend sent to me recently: http://seattletimes.nwsource.com/html/healthscience/134327382_brain12.html What I understood it to say was that, among some classical music lovers, if they suddenly find themselves more attracted to pop music than their traditional staple, then there tends to also be a correlative decrease in their brain functions. And although the article was not explicit, I understood classical music to be defined largely by the output of the Baroque, Classical, and Romantic periods, i.e. tonal music. Then my question is, what about "modern" classical music? What does the new appreciation of some of the less tonal composers say about brain function? I think this is a legitmate question, because a lot of people-- smart people-- who like "classical" music are not that enthralled by Bartok or Piston (I know some of you might not consider Bartok and Piston "modern", but for the purposes of this posting let us please agree that they are!). So, if I've been a lifelong adherent of tonality, and then one day I realize that Haydn,Mozart and Bach are kind of boring, but instead of finding an interest in pop music I gravitate towards Bartok and the like, does this mean that a change has occured in my cognitive functions? And if so, in what direction? hector aguilar
