You know your dulcimer has a hold on you when...
General mountain dulcimer or music discussions
But as to pulling up on the strings? I would be afraid there might be a chance of the string 'slapping' the frets if string was pulled hard enough.
From Jean Ritchie's Dulcimer Book: "Brace the thumb of the right hand against the side of the fingerboard near the right hand end. Play, with a slight lifting or plucking motion, the melody string and second string with the forefinger, and the third string with the middle finger." Also The Best Dulcimer Method - Yet, (the only Dulcimer book I've seen in the past 40 years) repeats "Play with a slight lift in plucking motion." As far as string buzzing it hasn't been a problem, but my action is a little high. Not nickel and dime, more like a buck and a half.
Didn't know how to post that original quote.
Also sorry it took two weeks to respond, but, life..
