Most of the chords notated as \chord{G} are actually played xxDGBx, i.e.
just the three open strings of the G chord. In other words, fake it.
In case you were wondering, Charles Babbage was born on December 26,
1792. He invented the stored-program digital computer, which he
called the Analytical Engine. The Analytical Engine was also the
first unfinished computer project. Contrary to popular belief,
the mechanical precision of the time was quite capable of producing
it, but Babbage kept changing the design and eventually ran out of
funding. It's an old story.
