ANYWAYS - does yours have frets like a guitar, or are there some places where the spaces between frets are much bigger or smaller than on a guitar? Mountain Dulcimers are typically diatonic as I understand it.
The spaces are bigger and smaller in places. This isn't my dulcimer but mine looked almost exactly the same (It got lost in one of my frequent moves):
