12 Bar Blues Chord Progression – Blues Basics

The 12 bar blues chord progression is the back bone of the blues besides being the basis for many pop and country songs.

This is where Eric Clapton, BB King and every other Blues player started and still use this progression for a lot of their songs.

This music used to be called Rhythm and Blues when the Sax and Piano were the lead instruments which is still one of the Blues styles today. You just don’t hear that term much anymore. It got shortened to Blues

The Rolling Stones early albums have many rhythm and blues tracks on them with blues chord progressions.

12 Bar Blues Basics

The blues uses the three major chords from the major scale. The I, IV and V chords. In C the chords would be C, F and G.

F♯ and G♭ are the same pitch just a different key for writing music.

12 Bar Blues in A

This is a fairly simple blues chord progression using 9th chords for the IV and V chords

This could also be done with just plain major chords or with all 7th chords which is what you will probably see in most sheet music for blues songs

These progressions can get quite complicated when using chord substitution.

For right now you just need to understand the basic progression because all the other versions are still based on this simple progression.

This is referred to as a quick change blues progression because of the change to the IV chord in measure 2. A lot of the time the I chords plays the 1st 4 measures

Also the A7 on measure 4 is kind of an out of date sound played this way that you don’t hear too often anymore. It tells you your about to change chords.

Here are the chords. I couldn’t make the staff big enough so you could see the chords diagrams clearly
