JPP is a group of Finnish folk musicians, mainly fiddlers, hailing from Kaustinen. The name originally meant Järvelän Pikkupelimannit, the small fiddlers of Järvelä, but today the group only uses the acronym JPP. The group still uses the Kaustinen traditional settings with fiddles, harmonium and double bass, although their arrangements are more advanced than earlier generations of traditional musicians in the area used.
