What is "spilapipa"

The spilåpipa (or spelpipa, spälapipa, låtapipa) is a type of fipple flute traditional in Sweden. It is traditionally from the pastoral/transhumant cultures of that country, though more widespread in the modern era. It is originally most common in the transhumant areas, generally north of Svealand. During the 1900s, Älvdalen was a centre of conservation of spilåpipa music, and accordingly that area's name for the instrument has become the most widespread. A significant variation of the instrument is the härjedalspipa, but it has many variants. The instrument has experienced a revival in recent decades as modern folk musicians have become curious about traditional instruments.
