 For example, in playing the F on the first string, first fret (often the second note ever fingered after open E, first-string) there is a tendency to put the second finger on top of the first to hold the note.Holding a note with two fingers, 1 & 2, however, puts the reach between the fingers between the second and third, the hardest reach.The easiest reach is actually between the third and fourth (pinky) fingers.
