How are these licks "advanced?"
The easiest alternate picking licks are those that consists of three notes per string played from the lowest to the highest or vice versa. It's easier to follow the scale up and down than it is to mess around with the notes on each string.

So any lick that consist of sets of three notes up or three notes down on each string would belong in the "easier" department, where as licks that consist of different combinations of 3 notes would be harder. Or more advanced if you like.

In this video we're going to explore more ways to use the alternate picking technique. This means that we're going to put more demand on the fingers of your left hand and! we're going to challenge the right hand as well.
