The group's repertoire consists of traditional tunes, as well as newly-composed music in old-style dance rhythms -- polskas, waltzes, schottisches, etc.
Most of the members have studied at the Sibelius-Akatemia University, mainly at the folk music department.
Jouni Järvelä and the Varila brothers were later succeeded by Matti Mäkelä and Tommi Pyykönen, first on tours and then also on recordings.
While JPP releases fewer recordings today than in its early years, the group still tours in both Europe and North America, mainly performing at folk music/world music festivals.
Mauno Järvelä, who used to play in symphony orchestra, is currently very active as a teacher of violin and pelimanni music.
