Watch the String Skipping: Level 2 online guitar lesson by Chris Buono from Guitar Gym: String Skipping
Level 2 Skipping Strings Workout #1 is a four bar sequence of major, augmented, minor, and diminished triad arpeggios. The catch here is the single string skip from the lower 1-3-5 portion to the 1-3 portion of the arp. Watch for the logical sequence of adjustments from one chord type to the next - it makes moving through the arpeggios easier to get under your fingers. Also, be mindful of the slight difference in setup for all the E-based arps as they have the top 1-3 portion lowered a half step in relation to the bottom portion due to standard tuning.
