Overtone flutes can be found in many countries throughout the globe, although in many cultures this flute is no longer produced and played. The only other known folk overtone flute is Norwegian seljefloyte or the willow flute. On the other hand in Slovakia, koncovka is widely popular and crafted already for centuries. Thus, it is true to say that in Slovakia you can find the best quality overtone fipple flutes (Koncovkas) available. On contrary, the unique Fujara shepherd bass flute can be found nowhere else but in Slovakia.
