Inside and outside picking
In'n'out, yummy!
This exercise is all about changing strings while alternate picking! The two important terms here are of course inside and outside picking.
Outside picking happens when you change to a higher string after a downstroke, or to a lower string after an upstroke. It's quite easy to imagine that if you were only to play these two notes on the stings your pick would be doing this kind of motion (if you're going from the D to the G string and vice versa):
Inside picking is just the opposite of that! This happens when going to a lower string after a downstroke or to a higher string after an upstroke. Here's a nice picture so you'll see what I mean:
Pattern 4
This is an outside picking example. The outside picking occurs when you switch to the 3rd string and back. Play it!
The inside picking lick is very similar but you'll be going from the 3rd string to the 4th.
Here's another outside picking lick. It doesn't go straight back to the original string but plays two extra notes on it. Don't worry, it's just as cool!
The next inside picking lick is constructed in the same way!
If we combine licks 1 and 3 we get this cool lick:
And the final lick - the inside picking licks combined:
