Actually, John calls it a lap because he can't SPELL Appalachian....LOL......Actually he gives you great info there. Past that point you begin to get into various "modal" tunings which broadens the range of the instrument for different types of songs, giving them the proper "feel" and sound, for lack of better words.

Several of the threads linked above are directly discussing tunings and getting started. There are also some excellent things on the history of the instrument. That should provide you with lots of good reading and info.....and when you have questions, we're here (sadly, just about all the time as none of us have a real life.....***sigh***........) I would also suggest a book or two but right now you have plenty of reading right here! Among other books that are excellent is one that almost all dulcimer players have......"The Dulcimer Book" by Jean Ritchie. She is the "Mother of the Mountain Dulcimer" and had it not been for Jean, the instrument would be little known today. She's a living legend and an American treasure and lucky for you, also a Mudcatter....look for "Kytrad" on the threads.

Welcome again to the 'Cat..........
