I haven't listened to the snippet, but let me hazard a guess: a quintet by a 19th century woman composer could be Louise Farrenc---but then it would be not so much Brahmsian as Beethovenish/Mendelsohnian. Appropos the mystery theme, someone commented that it is easy to absorb someone else's tune, then imagine that one has made it up oneself. Hmmm, that's virtually all I do when I improvise on the piano, except that I am SOMETIMES able to remember whose tune I started with. Maybe that is actually the basis of original composition, except that the composer draws on and reassembles tiny bits of previously heard music. Could it be that "creativity" is really a form of very fine-grained reconstruction? Cheers, Jon Gallant Department of Gnome Sciences University of Washington
