12-Bar Blues

The normal "12-Bar Blues" is the rule of 3 chords. Usually referred to as "I-IV-V chords (alternatively as tonic-subdominant-dominant). The 1 Chord is the root of the song, can be derived from the other two.

Here we have the scale (without half steps): C D E F G A B C
For a blues in C the I-chord is automatically the C chord and so would the IV chord is an F and the V chord, a G to be.
To test simply count times:

I   II III IV V
C D  E  F  G  

The same, of course, you can apply for any other typical blues song, simply count the chords, if you with the fundamental, ie I have the chord. Finding the simplest and most ideal way is the right chords to use a circle of fifths. In the below you need only look at the circle to throw your I-chord is always the root and at the top. From there, you count from easy. Some things are really easier than I thought, right?

Exercise: Finding out on the basis of counting the I IV and V chords of the following frequently verwendetn keys for 12-bar blues.

1. A
2. D
3. G

Solution:
1. I = A D = IV V = E (eg Stormy Monday Blues)
2. I D = IV = GV = A (eg Good morning little school girl)
3. I = G IV = C = V D (eg Oh Pretty Woman)

Songs are based on I-IV-V chords:
Crossroads (original by Robert Johnson, played by Eric Clapton, Rolling Stones, Lynyrd Skynyrd, etc.)
Good Morning Little School Girl (Original Sonny Boy Williamson, etc. played by Jonny Lang)
Malted Milk (Orig. Robert Johson, played by Eric Clapton and Others)
Pretty Woman (Original Albert King, among others played by Gary Moore)
Pride and Joy (Stevie Ray Vaughan)
Stormy Monday Blues (original? played, among others, SRV, Albert King, Allman Brothers, Gary Moore)

Let's start with the practice! 

Now plays once a very simple 12-bar blues in E.
Our 12-stroke follows the equation: E (4 bars) A (2 bars) E (2 bars) B (2 counts) E (2 bars)

For proper practice you can also use the GuitarPro file that you can easily practice until you can play this important rhythm liquid.
