Welcome to my second column for CFH and thanks for checking it out.
The first example, it is an arpeggio of Fmaj add9 with economy picking.
The second example is a stretching exercise, it is very difficult to play in that position, so transport it where you feel comfortable or it could be painful. With the time you play it as this writing.
The third example is a Bmin legato lick. It combines six notes and seven notes, and I don't use up strokes, I use the middle finger.
