There are many other chords and chord shapes you will encounter in blues and particularily in swing- and jump-blues guitar.

These include minor chords, minor seventh chords, b13th chords, etc.
All of them have several shapes you can find on the fretboard.

It will take some time to get a good grip on all these chords and their shapes, plus when you can use them.

The theory behind all of this is not that hard.
Music is nothing like maths or geography.

Don’t try to grab this all at once.
It is not and will never be part of any SAT test.

The quicker you learn this stuff, the faster you’ll forget it.
All this theory takes time to sink in.

Try all of the examples, chords, riffs, horn lines, etc and pick up what you like.
Once you start playing, check your brain at the door and try to get into the feel.

Blues is about feeling and emotion, first and foremost.

Only if you get to the point of asking, “but why does it work this way?” should you come back to this chapter and then you’ll find some answers.

But how to use all this stuff?

Let’s get back to what blues is.
Blues is tension and release, call and response, one man singin’ about his suffering and people dancin’ to it.
It’s a story to listen to, to react to.

All these elements have found their way into the music.

You might have noticed that although we are playing major chords (meaning G7 and not Gm7), we’re playing a BLUES SCALE on top of it; a minor scale!

This contradiction is exactly what blues is all about.
The tension that is created by playing major chords with a minor scale makes for the ‘blue’ sound.
Especially the major third of the chord G7 against a minor third in a melody sounds blue.
By bending these notes you can produce even more tension.

The fact that the blues scale only uses five notes (plus the flat 5) gives it a sharp edge.
This is because the space between some of the notes in the scale is bigger than in a regular minor or major scale.
These scales contain seven notes.

A blues scale can be used to solo over all three chords.

Using the mixolydian scale will give you some more note options and make the sound a little milder and smoother.
If you mix it up with the blues scale, this gives you the best of both worlds.

Integrating the Mixolydian scale into the Blues
is what this book/website is all about.

This is what we do in Swing- and Jump-Blues!
