There's lots of good content on dulcimerschool.com. I stand by all of it. The new site, mountaindulcimeratoz.com, was initially going to just be an online version of my four-day intensive, but I believe it's best if I put all new content on there as well. For now, Dulcimer School is like my first online textbook. MountainDulcimerAtoZ.com is my current one. The video version of my four-day intensive on mountaindulcimeratoz.com does walk through concepts more in order, and each concept is covered beginner through intermediate to advanced.
