Visit the shores of Lake Siljan in Sweden and the fjords of Norway to watch the birth, near death, and resurection of music and dance tradition. Scandinavia has a rich tradition of music played on the fiddle and it's variations, and is a case study on how geography and history can influence culture. Meet instruments like the Hardanger Fiddle (twice as many strings as a regular fiddle, whose sound is featured in the Lord of the Rings) and the Nyckelharpa or "keyed fiddle," which is, well, a fiddle with keys. Their musical tradition has been shaped by the mountains that isolated them and the trade routes that served as paths for tunes as well as physical goods. It was disrupted by the arrival of christian religion and changed again by the technology-induced end of isolation.
