This lesson will show you some essential blues guitar chords and their
common variations. Bear in mind that there are no set rules on
which chords you can play, but there are staple chords that have
defined the blues sound for over century.
This lesson goes hand in hand with the blues
chord progressions lesson.
Simply apply the chord variations you learn here to the forms covered
in the progressions lesson.
You'll probably have come across some of the chord forms shown in this
lesson, naturally as you've progressed with learning guitar.
However,
I'll show you some modifications of those common open and
barre chord forms that will give them a more bluesy touch.
Open position blues guitar chords
Open
position refers to chords that use open strings, most
commonly chord forms down at the first few frets. Most people learn
open chords as beginners (e.g. E, A, D, C and G major).
They provide us
with full, vibrant chord voicings and, in the context of blues, we're
most interested in the dominant
7th variations of these open chords.
E major is the most common blues key on guitar, so you could think of
E7 as the 1 chord, A7 as the 4 chord and B7 as the 5 chord.

Movable blues guitar chords
When you start playing blues further up the fretboard, you'll need
chord forms that allow you to play the same chords in any position.
These are called movable chord forms/shapes because they keep their
formation as you position them up and down the fretboard.
The most common movable form is the barre
chord, which I'm sure you're familar with. Just like with
open chords, there are specific variations of these barre chords that
give us more of a blues flavour.
The two main barre chord forms used in blues are the E and A form (or
shape). These chords are so called as they are rooted on the E and A
strings respectively. You can use either of these positions for the 1,
4
or 5 chords in a blues progression, but it's most common to use the E
form for the 1 chord and the A form for the 4 and 5 chords.

There are also movable chord forms that don't involve a "barred" index
finger. Some of these chords are cut down variations of the fuller
barre chord forms, often referred to as "shell chords" because they
contain only the most important chord tones (e.g. the neutral 5th is
often omitted).
Similar to
barre chords, the most common shapes are rooted on the E and A strings.

Each time round the blues progression, try mixing different variations
and see what you can come up with.
Other blues chord variations
While it's common to play straight chords through a blues progression,
guitarists often use chord or lead phrasing to embellish the 1 4 5
sequence.
Blues phrasing will be covered in its own lesson, but here are a few
examples to get you going.
Another example of a common phrase, using our open E major position...
The audio example gives you some ideas on how you can play that
variation. Will explore blues technique in a separate lesson!
That one is built around the (E) minor pentatonic scale - a staple
scale in blues music.
Blues turnaround chord phrases
The turnaround occurs most commonly in the last 2 bars of a blues
progression. In short, it prepares the listener for the return back to
the tonic and the start of a new 12 bars (or however many bars the form
is).
A typical example in the key of E major is a descending chromatic
phrase using
the top 3 strings as follows (again, the audio example shows you a few
ways you can play it, for example picking vs strumming)...
