Power Chords
vs. Barre Chords
We all know
that they are different, but which one do you play in
a given piece? Well, the options are left quite open,
but many times it actually depends on personal ability.
While power chords are MUCH easier to play than many
barre chord formations, the power chord tends to muddy
up a passage and doesn't offer a bright consistent tone.
This is the main reason that power chords are used in
heavier music. As you know, power chords are most frequently
used with distortion, but that isn't always the case.
In this series,
we are going to alternate between power chords and barre
chords, allowing you to hear the difference between the
two. This should be a simple run of power/barre chords,
so even if you haven't mastered difficult barre chords,
this exercise should work just fine for you.
Exercises
In this power
chord exercise, the first bar is all quarter notes. All
you have to do is play them as you see them. The second
bar is using eighth notes. The '5' notes that each chord
is a power chord. The '5' notes that that in addition
to the root, you are also using the 5th.

Now we start
introducing some barre chords instead of the power chords.

second bar uses eighth notes.

Now we play
barre chords instead of power chords using the same format
as above:

As you can see,
there is quite a difference between hearing the sound
of the power chord vs. the barre chord. Most often you'll
find barre chords for acoustic as power chords don't
provide the full tonal quality that most acoustic guitarists
need.
