Watch the Pentatonic Picking Exercise 3 online guitar lesson by Jeff McErlain from Beginner Blues-Rock Soloing
In this exercise, we're going to introduce string skipping. As the term suggests, we're going to pick two notes on one string, skip a string, and pick two notes on the next. String skipping is an excellent exercise for both left and right hand accuracy. As you go through the exercises, do so very slowly and pay very close attention to your pick hand as that's the one that usually gives us the most difficulty.
It's also important to pay close attention to muting the strings properly. The muting comes from both my left and right hand, on the left hand it's usually my first finger that flaps across the other strings to make sure that they do not ring out. On my right hand, my picking hand, muting is done with palm of my hand resting gently on the bridge on the strings that I've already played. Try practicing these with a clean tone at first. If you're a guy who likes to play with some overdrive, you need to practice this with the overdrive too, as muting becomes a much larger concern. The overdrive adds increased sensitivity and noise that can easily ruin your day!
