The twelve bar blues

A simple framework for understanding its structure,
each chord is a measure of 4 beats (counted one, two, three, four).

Chord 1 Chord 1 Chord 1 Chord 1
Chord 2 chord 2 Chord 1 Chord 1
Chord 3 chord 2 Chord 1 Chord 3

Note: These twelve measures are grouped into four measures 3 times.

The high line has four measures of the first chord.
The middle line : two measures of the second , then the first two measures.
The bottom line is a summary of closure:
it begins with the second and third chord and the first chord,
the twelfth measure calls the third and final chord.

And then ? ... It begins again!

Exercise : 1 = E chord - chord 2 = A - 3 = B7 chord or
Exercise : 1 = C chord - chord F = 2 - 3 = G7 chord...

The two seventh chords most commonly used

accord de septième C7. We only play four notes (to use for the first chord) down 2 frets D7 we get (still down 2 frets = E7 etc ... )

accord barré de septièmeF7. This bar chord starts at the top of the guitar neck F7 first fret down 2 frets we get G7 (in the third fret). You can play six notes (Use for the second and third chords in our example).
Both chords can be moved by keeping gaps frets: to play in all keys.

We try to play chords on this music.

1st = C7 chord.
2nd chord = F7.
3rd chord = G7.

Which chords to play the blues ?

Note:
The chords are seventh e.g. C7 - F7 - G7,
chord between the first and the second chord is an interval of fourth,
chord between the first and third is an interval of fifth.
Note: intervals always follow the progression: A B C D E F G etc ...
and this starting any note of the scale.

Explanation:
If your chord is A your second chord is D = fourth (starting from A).
Example: A(1) B(2) C(3) D(4). D = fourth.
If your chord is A your third chord is E = fifth (starting from A).
Example: A(1) B(2) C(3) D(4) E(5). E = fifth.

Conclusion :
The three chords of blues are always:
A7 D7 E7 if the first chord is A.
B7 E7 F#7 if the first chord is B
C7 F7 G7 if the first chord is C
D7 G7 A7 if the first chord is D .
E7 A7 B7 if the first chord is E
