Music Composers Unite!
This is the format with which folklore is often performed. I had a few themes in my head when I arrived to medieval Croatian town Porec. There in the alleys I frequently could hear wonderful folk songs giving a large impression on me. And I realized it was worth a try to arrange"my" themes accordingly. However "my" in quotation mark since the starting themes are influenced by others as you can hear if you take a listen.
All the best,
