My goal in this exercise is to ingrain alternate picking deep inside your brain membrane! This will increase speed, tone, and evenness in your pickin’. We do this by playing a 2-octave G and A major scale while adding a series of hammer-ons and pull-offs to CAUSE you to learn alternate picking. Follow the pick stroke arrows in the tab!
