Triplet Rhythms - Rhythm Fundamentals: 4 is a video guitar lesson presented by Massimo Varini and is sourced from Pop Guitar Survival Guide.
Playing in triplets changes the pick direction every fourth beat. On the first beat we'll start with a downstroke, on the second beat we'll start with an upstroke. It's very important to pay attention so that you have the same weight on both directions, down and up. We can also play the triplets using what I call the circle of three: three strikes (D-U-D, Down Up Down) as a pattern.
