i have a zither alike the karas third man zither,i believe it is a concert zither or similar,with a fretted side with five strings,there are two tunings for the fretted side. munic tuning-from the edge inwards A,A,D,G,C, THE OTHER ,VIENNA WHICH I BELIEVE TO BE ANTON KARAS TUNING,CORRECT ME IF IM WRONG IS A,D,G,G,C I FIND IT DIFFICULT TO TUNE UP THE ACOMPLIMENT STRINGs BECAUSE I PLAY BY Ear AND DONT READ MUSIC.I WISH SOMEONE IN THE KNOW, WOULD STRUM ALL THE STRINGS OPEN ,FROM ONE SIDE TO THE OTHER,"very slowly lol ON YOUTUBE.Having said that you can get the tuning for concert or alpine or elergy or karas zither simply by typing "zither stringing"you will get both tunings,hope this helps some folks,if you would like to here an english cajun band,chek out the dawgs.   cheers,jake.ps aint no zithers in my band though i play the fiddle as you might have guest.
