Walpipe
''Not to be confused with a different walpipe, a bagless instrument made from a cow's horn.''
The walpipe is a type of bagpipe found historically in Lapland (now known by its native name, Sápmi), a region of northern Scandinavia inhabited by the Sami people.
Late 18th century researchers noted two bagpipes in Lapland: the sak-pipe and the wal-pipe.
