The piva is a type of bagpipe played in Northern Italy and the Italian-speaking areas of Switzerland, such as Ticino. The instrument has a single chanter and single drone.
In Italy it was traditionally played in an ensemble with the piffero (folk oboe) until the piva was replaced by the accordion in the 1950s.
The piva appears to have died out in Switzerland in the 19th century, but was revived in 1980 by Swiss-German folk musician Urs Klauser.
