The mountain dulcimer was not originally used to play the blues, and the diatonic fretboard presents some important obstacles for those of us who want our dulcimers to weep and moan and sing the blues. But those obstacles can be overcome. This page offers resources for those who wish to explore the world of the blues on the Mountain Dulcimer.
Steven K Smith has three very helpful pages of material on the blues at his website.
On a couple of occasions I taught introductory blues lessons at our monthly RCD gatherings. I will slowly be uploading relevant material here. The first piece is an explanation of the basic 12-bar blues structure, which you can find here.
Bing Futch provided us all an introduction to the Blues when he visited RCD at the Strum Shop in October, 2015. Much of what he taught us can be found in his Dulcimer Sessions Blog entitled Mountain Dulcimer Blues 101. [note: This material had been hosted by Mel Bay but is no longer available. Hopefully the link will be updated soon.]
