Behold the single most annoying musical instrument in existence. Originating from the Troll Homelands, this instrument when encountered is usually badly tuned and most people who carry one around either think it's too simple to need to learn to play and just blow into it or just never bother to learn it properly. High-pitched, mostly tuneless, and to most people, more useful as firewood.
Troll children who master the recorder are offered the chance to learn the Flute.
