Watch the Tapping online guitar lesson by Chris Buono from Guitar Gym: Tapping

Level 3 will get you into tapping within Heptatonic scales through three
essential Diatonic modes: Ionian, Mixolydian and Aeolian. All in 16th
notes you'll literally legato your way up and down the neck using
tapping and fret hand legato techniques. It's totally fun and a great
set of Workouts! This approach enables you to play otherwise impossible
sequences. Take advantage of the fact these three Workouts play off the
same pattern. Meaning: Once you learn Workout #1 the following two
Workouts are morphed in parallel according to the modal formula at hand.
That said, keep an eye on the varying fret hand sequences as well as
the tapping note changes throughout the Workouts. Ready?
