4 equidistant strings/McCarty tulip dulcimer
Instruments- discuss specific features, luthiers, instrument problems & questions
@jim-hedman @robin-clark Okay, Jim and Robin, I have some data we can work with. I tried plugging this into the StewMac calculator, and it keeps telling me the 8th fret is the octave. Maybe they are counting the zero fret. Anyway, from the zero fret to the 7th is 335mm. If you double that to place the bridge, the end of the wooden bridge assembly lines up exactly with a couple of pinholes that were clearly put there by the builder. (There is a second set of pinholes about 1/4" frther from the zero fret, but that's something for later.)
Here are my measurements, all with reference to the zero fret in millimeters:
z-1 59.5 mm
2 129.5
3 164
4 222
5 267.5
6 292
7 335
8 370.5
9 404.5
10 421
11 448.5
12 472
13 486
14 506
In the StewMac calculator, I inputted a 670mm VSL, 14 frets, and selected Dulcimer. Should I be doing something different?
A couple of notes concerning Robin's post...
- I don't think anyone has changed the action on this instrument.
- On a 4-equidistant dulcimer, would the first string be considered the melody string and the other three drones?
- "Tune to D,A,A for your drones then tune the melody string so it sounds a 'd' note at the 3rd fret an octave above the bass string. Play the scale on the melody string against the drones. If it sounds OK (see below) except for the open melody string sounding sharp then your problem is simply the zero fret position. My guess (and it is just that) would be that the maker took a fret template from an older dulcimer with a bridge but fitted a zero fret. A bridge in the same position as that zero fret(particularly a high one on an old dulcimer) would have made those first half a dozen frets pull sharper."
Can you suggest typical string gauges? Just best guess and estimate.
I apologize for seeming dense, here, but would what I would tune to be DAAd? I have a fairly light gauge set of John Pearse strings on this dulcimer. Perhaps I should have something like 12-14-14-22 on this one.
