Appalachian Dulcimer is another of the 'Folk' instruments which are relatively easy to play , and so tend to only get used for 'simple' tunes , as is the whistle . I used to know a lad who play Jigs and Reels at breakneck speed on App Dulc , and was also know to play Blues on it as well . My advice is play what the Hell you feel like playing ,regardless of people who say "Thats NOT an Appalachian Dulcimer Tune".
