Watch the More "Shwonk" online guitar lesson by Geoff Hartwell from Guitar Lab: Electric Slide
Welcome back for more from my favorite onomatopoeia! This is another plucking hand technique like the “Shwonk” as a way to emphasize single notes, but in performance it’s actually more like brushing the strings with the back of your fingernails. It takes a very light touch, so don’t whack the strings too hard. This works best on the first string. One of the most important principles is to make sure you’re using your thumb on your plucking hand to guard and mute all the lower strings that you DON’T want to ring out.
