"Jouhikko" is the name commonly used by the Finnic peoples. Scandinavians call it Taglharp; in Estonia this instrument is commonly called Talharpa  (both names mean "tail harp")... It has existed among the Northern Germanic, Scandinavian, Finnish, and Slavic peoples in many different forms over a period of thousands-of-years. It was an innovation from ancient Proto Indo-European Bow-&-Arrow Horse Cultures. The fundamental design features of this instrument include two-or-more (typically three) music Strings of horse-tail, attached at the  top to tuning pegs, and at the bottom to a "Tail" piece with a Bridge somewhere in the "middle". The sound is achieved when Strings are played with an arched Bow (also with horse-tail string) through a hollowed-out "Soundboard" & "hole/s". The melodies are played with the hand opposite of the hand holding the "Bow"; through a large open area at the top of the instrument fingers are pressed against the Note Strings. It is a very simple and ancient sounding instrument that has been gaining in a resurgence of popularity. The Taglharp has been featured prominently with popular musical artists from Italy, Russia, Scandinavia, and many other countries including North America...
