Capo with open high E-string
A capo put over five strings instead of six can give a guitar sound with resemblance to open tunings. Very nice ringing chords are one of the pleasent things that happen.
In this article, the high open E-string open (the thinnest string) is left open whereas capo is pressing down the rest of strings. The idea can be applied in all possible capo positions, but some will be less thankful. Perhaps the smoothest transition from standard tuning thinking with this approach is with the capo on the fifth fret (see below).
