In this lesson we are going to look at a 12 bar blues in the key of G with a
moving bass line in between each chord. I'll take you through the chord shapes and
the bass line, and then we'll put it all together.
Ok, the first chord I'm using is a G7, which is a barre chord. Barring on the third
fret, and I'm putting my second finger on the G string in the fourth fret, my
third finger on the A string in the fifth fret, and that's my G7th chord.
We drop right underneath the four chord, still barring the third fret. Third
finger goes on the G string, fifth fret, and my fourth finger goes on the
B string, fifth fret. Going to strum that from the A string down.
G7 ... C7...
The A7 chord that I use in the progression, just simply take the G7
chord, move it up to the fifth fret. Root note there on the E string which is my
A note ... and there is my A7 chord.
Like I did before dropping underneath for my 7th chord now of the A string.
Root note coming of the A string on the fifth fret ... that is now my D7
... G7 ... C7 ... A7 ... D7
Ok, we're going to our E7 chord now. I'm playing that as an open chord, or
first position chord, putting my first finger on the B note which is on the
A string second fret, and placing my first finger on the G string first
fret, and I can play my open E string right through ... gives me my E7 chord ...
Now, I'm just going to strum through those chord shapes in 4:4 time, just following
the blues pattern, starting with my G7 chord.
One, two, three, four,...
(G7 four times) ... see my C7 (play it four times) ... back to G7
(play it 8 times) ... C7 (8 times) ... back to my G7 (4 times) ...
into my first position E7 (4 times) ... up to A7 (4) ... B7 (4) ...
G7 (2) ... E7 (2) ... A7 (2) ... B7 (2) ... resolve
back on the G7 chord to finish off (1)
Ok, once you've got those chords under control, we need to now add the bass line,
and I'll take you through that step by step bass line relating through each chord shape.
Ok, the bass line for the G chord or G7 chord is going to be my
B note played on the A string second fret, and then with my fourth finger,
I'm playing my D note on the fifth fret, so I get a B, D, B ...
place my fingers on the G7 chord ... B, D, B ... one more time ...
Now dropping down to my C7 shape ... I play the notes E, which is on
the D string second fret with my first finger, up to a G note which
is on the fifth fret of my D string. Once again ... C7 chord ...
Going from my G7 ... C7 ... back to my G7 ... return to my
C7 chord ... and back to my G7 ... at this point I'm going down to my
E7 chord on the open position ...
Bass line for the E7 chord, fourth finger on G#, first finger on B
on the A string second fret ... E7 chord ... up to the fifth fret where
I play my A7 chord. It is exactly the same shape as we did in the G
position, except we are now in the fourth fret with our first finger and on the
seventh fret with our fourth finger ... A7 ... underneath it D7 ... and
I'm playing, again, first finger on the D string fourth fret up to the fourth
finger seventh fret of the D string ... and then back to my G7...
I just simply finish the whole cycle with my turnaround going from G7 to E7
to A7 to D7 closing out on the G7 chord ...
Starting off with our G7 chord ... into our C7 ... back to our G7 ...
into our C7 ... back to the G7 ... into the first position E7 chord ...
A7 ... D7 ...
Now let's speed it up ...
Let's take a look what I'm doing with my right hand. Ok, so I'm using a pick,
strumming the chord on the downstroke, and I'm picking all downstroke, B, D,
B ... or 1, 4, 1 ... into my C7 chord, all downstroke ...
A7 ... D7... and just downstrokes on the strum when I go through the
chord turnaround G7, E7, A7, D7 and finish on my G.
You will need to have a fairly good understanding of barre chords both on your E
and your A string. There is some information on the web site; a couple videos
that relate purely to barre chords. You might want to check those out.
Work on your chords changes first, and then add your bass line. Work your way through
it slowly. Good luck with it. Until next time, I'll see you then.
