…as the good Doctor said; it’s made with three strings and out of wood. If I may elaborate, in addition to the Professor’s observation, it has wooden tuning pegs. He didn’t fail to mention it, it was at the time the method used. There were not a lot of mechanical tuners in the mountains a hundred years ago! Most had 14 staples, and some had frets. The finish was oil or varnish, and after many years they would turn very dark. A few were painted, because that’s what the customers wanted.
So I have reasoned there is nothing wrong with the dulcimore. First, it is much easier to define, as I have. Try to define the “dulcimer”! Yes it has strings, as many as you like. Mechanical tuners sticking out every which a way. No limit to the imagination as to size, construction, and sound. You can build a guitar and call it a dulcimer, and no one will question it. But the dulcimore has a sound like no other. Described “bourdonnement” . I had to look that one up and update spell check while I was at it.
The masters have given their best experienced insights to the making of the dulcimer. Many will directly contradict the other, hard wood, soft wood, brace, no brace, even in the finish. But the dulcimore has the resonance like no other, and that’s why it sounds so sweet.
