As we all know, Liszt's 19 Hungarian Rhapsodies contain and conserve some Hungarian and Gipsy tunes (although some of them are in a somewhat modified form). I'd like to know if there's any resource for knowing what exactly they are (I'd like to get information about as many of the Rhapsodies as possible, but my personal preferences include the 2nd, 6th, 9th, 12th and 15th one). In particular, I'm wondering:
- if these tunes/melodies have a title at all (my sad first guess would be no because they're folkloric);
- If so what the titles are;
- And if not, where could I find them, either in written form (notes) or in some kind of digital media?
