Watch the Pickin' Triads: Study 2 online guitar lesson by Jason Loughlin from Country Guitar Survival Guide: Lead Edition
Ok, so this is where it gets interesting. In this instrumental study we are going to embellish these triad shapes. In the left hand I'll be adding approach notes, passing tones, slides, hammer-ons and pull-offs. These are all ways of creating tension. I'm always playing around the triad shape. Being able to visualize the shape is important. None of these embellishments are limited to just one triad. They are all interchangeable. The right hand will be applying different picking patterns and rhythms. I would suggest learning the instrumental, finding one embellishment you really like and practicing it with as many triad shapes as you can. Then, start to introduce it into you solos and rhythm playing. When you're feeling pretty confident pick a new one.
