The only complicating factor is the fact that the B string starts on the 4th fret of the G string rather than the 5th fret like the rest of the strings (all strings, except B, start at the 5th fret of the next lowest string, A is the 5th fret of the E string, D is the 5th fret of the A string and so on. ) Because of this, the pattern breaks at the B string.
