Dulcimers are part of the zither family of stringed instruments. The hammered dulcimer is both a percussion and stringed instrument. Where pure zithers are bowed, the hammered dulcimer is played with two hand-held “hammers” which are used to strike the strings to make sounds. Found in many cultures - Greek, Roman, Southeast Asian, Eastern European and others - it found its way into folk music in the United States in the 20th century. The Mountain or Appalachian Dulcimer is a four-stringed, plucked and strummed instrument. Smaller in size than its hammered cousin but larger than the zither, it is popularly used in old tyme and roots music and forms of this style of dulcimer are also found in other cultures.
