Blues Guitar Chords
The 12-Bar Blues, also called the Blues Change, is one of the most popular chord progressions in modern music and features prominently in most forms of Blues music. Whenever it's played, it's also instantly recognized as the classic Blues signature sound due to its mellow and melodic feeling. This is the stuff Rock & Roll was born from. Let's teach you how to play it...
12-Bar Blues Rhythm
Like its name implies, this progression is played over 12 measures or 48 beats (12 x 4 beats per measure).
For a listen at the 12-Bar Rhythm watch the following. On this video I'm playing a basic 12-Bar Blues progression and counting the bars as I play. This should give you a good idea of the beat we're going for.
This free guitar lesson will teach you how to play the 12 -Bar Blues with three easy chords. This forms the foundation for any form of Blues music.
A note on counting: When counting bars, most people do it like this:
1, 2, 3, 4, 1, 2, 3, 4, 1, 2, etc. But by using this method, there's no way to keep track of what bar you're at.
Instead count like this: 1, 2, 3, 4, 2, 2, 3, 4 3, 2, 3, 4, 4, 2, 3, 4, 5, 2, 3, 4 etc.
This way you're counting the measures and keeping the beat, while at the same time counting the bars.
12-Bar Blues Guitar Chords
Here's the basic theory behind the blues guitar chords used in the 12-Bar structure: The normal 12-bar-Blues usually consists of 3 chords. These are technically named as the
"I-IV-V"-chords, or alternatively as
Tonic - Subdominant -Dominant.
The I-Chord (Tonic) is the basic keynote of the song. In this section we'll be playing most of our Blues in the key of E, so these are the three chords we'll be using.
I (Tonic) = E Chord
IV (Subdominant) = A Chord
V (Dominant) = D Chord
An easy way to know which chords make up the I-IV-V in a 12 Bar Blues, is by using this Chord Wheel illustrated on the right. You can right click + "Save image" to download and print a copy so you can keep it handy as reference.
