One more very useful thing to point out about the position used in bar 6 is that it is often referred to as the “B.B. box,” in reference to blues guitar great B.B. King. The “B.B. box” positions the root note on the second string, fretted with the index finger; in this case, this is an E note found at the fifth fret of the second string. Starting with the middle finger on C# (third string/sixth fret) and followed by the aforementioned E note, you then play G (second string/eighth fret), A (first string fifth fret) and B first string/seventh fret). It is thought of as a “box” because you remain inside the four-fret span, between the fifth and eighth frets, the entire time.
