The birch trumpet (Norwegian: neverlur, Swedish: näverlur, Latvian: tās̆u taure, Lithuanian: ragas, daudytė, Finnish: tuohitorvi, Estonian: karjapasun[1][2][3]) is a type of natural trumpet made of spruce covered with birch bark [...] Usually, the neverlur is a natural horn, having no fingerholes or valves. Normally, a player can play 10 tones from the natural scale on the instrument. In the modern era, the neverlur is primarily a cultural curiosity, used for the occasional fanfare.
