Watch the Scales online guitar lesson by Chris Buono from Guitar Gym: Scales Workouts
Level 1 Scales Workouts will put the venerable minor pentatonic in the spotlight. With only two-notes-per-string and basically only two fingering variations, this is a great scale to start with. In regards to the former you can apply a consistent alternate picking pattern involving both outside and inside pivots.
The three Workouts will be stationed in the XII position playing the E minor pentatonic scale - get used to it as you'll play this one a lot in myriad styles and scenarios. The first two Workouts split the scale into three-string chunks with the first Workout starting on the top strings. By the time you get to the 3rd Workout you're ready to play the entire six-string range with both outside and inside pivots. Throughout the three Workouts, you'll hear me constantly remind you about keeping unwanted string noise in check.
