Guitar chords, (chords played specifically on a guitar,) differ only
from other types of chords by virtue of instrument; they're simply a
series of three or more notes played together. These notes don't
necessarily have to be played simultaneously, however.
Broken chords (also referred to as arpeggios) are three or more notes
that aren't played at the same time but closely enough to still be
heard as a group or whole. And even the three-note rule is open to the
occasional exception; some guitar chords consist of only two notes,
but they still function as chords because they work diatonically in
the same way that a major or minor chord would.
Guitar chords might very well be the most important element of guitar
playing; after all, they're the basis of what makes a song. Most
people picking up a guitar for the first time figure out a few guitar
chords before even going for their first lesson, and still more teach
themselves guitar chords without any help from an instructor. Self-
taught guitarists learn guitar chords in a number of ways. Some learn
by listening to their favorite songs and slowly picking out the notes,
a common yet often frustrating process. Others figure out guitar
chords by learning to read guitar tab, a type of sheet music intended
for fretted instruments that uses a graph-like chart to show where on
the frets the fingers are placed. Both techniques are common among
those learning guitar chords, though the number of self-taught
guitarists who never learned to read tab is fairly high....
