Connection Between Hammered and Mountain Dulcimers?
General mountain dulcimer or music discussions
Not a dumb question Nate. There is no apparent socio-cultural link between Hammered dulcimers (a kind of psaltery) and the Appalachian dulcimer(a kind of fretted zither). The only commonality is the shared "dulcimer" cognomen. The hammered dulcimer was a popular parlour instrument in the 1700s and 1800s across Europe and the Americas. It evolved from a Persian instrument dating back to the 900s which spread across Europe in the early medieval period. The Appalachian dulcimer evolved from fretted zither brought to the Pennsylvania colonies in the late 1600s/1700s by folks we today call the "Pennsylvania Dutch".
You asked "...why is there such a noticeable cultural overlap between hammered dulcimer people and mountain dulcimer people?". The answer, IMHO is that they are both, today, uncommon folk instruments (not guitars banjos or mandolins), and both -- as Dusty says, originally pure diatonic. As you suggest, I too suspect that the connection only came about during the mountain dulcimer and folk music Revival of the 50s and 60s.
