As this thread represents the only post by Jaybird at mudcat (thus far), we should perhaps offer a welcome, and wait for some additional information about which kind of dulcimer needs tuning, and perhaps a bit of chatty gossip about why and where said Jaybird encountered such an instrument.

That being said:

Welcome to mudcat, Jaybird.

We need a little more information on what instrument you have, since "dulcimers" come in at least a couple of kinds, and we may get thoroughly confused if we don't know which kind you're interested in.

(Jaybird is probably off reading all the FAQs, but will surely be back soon.)
