12 Bar Blues and Power Chord Review


Last time we started to take a look a power chords.  Before we move on, lets review some of those ideas.

POWER CHORDS- REVIEW

A power chord is made up of a root note, its 5th and sometimes an octave. There are two forms that we looked at last time, a power chord with the root on the 6th string and one with the root on the 5th string. Lets review them with a song that is great for practicing power chords.

Foreplay Boston

The part below starts 30 secs into the song.

This song might be a little fast for beginners but go at your own speed. Learn the part very very slowly and get faster as you get better. Once you get a firm understanding of power chords, take a look at the definitions below and move on to the next topic.

DEFINITIONS

Tempo- the pace of a musical piece. Basically, it is how fast of slow the song goes.

12 BAR BLUES

The 12 bar blues is a progression that is a basis for the blues. The “12 bar” part of the 12 bar blues means that the progression is 12 measures long. There are four chords used in progression: I, IV, and V. The basic form is show below.

12 Bar Blues – example (power chords)

12 BB

So that is 12 bar blues using power chords.  They example song I will leave you will is very similar to the example we just did.

 Leave My Girl Alone [live]Stevie Ray Vaughan

This progression in this song is only changed slightly. This is what it looks like.

| A | D | A | A | D | D | A | A | E | D | A/D | A/E |

As you can see the only changes are in bar 2 there is a IV chord (D) instead of the I chord (A) and bar 11 ends with a D whereas in the example before it was A for the whole measure.  Play along with the song. It is very slow.

  1. in 12 bar blues can the 3 chords be used in any progression

  2. The three basic chords used in any 12 Bar Blues progression are the I, IV, and V. This means that if you are in C maj (C D E F G A B), then you would use the I chord (C) the IV chord (F) and the V chord (G). No matter what key you are in, you will always use the I, IV, and V chords, you just have to work out what they are for that particular key. 12 Bar Blues is made up of 12 measures, as the name suggests. The normal progression is I I I I IV IV I I V IV I I. If you use one chord per measure that gives you 12 measures. There are various chords you can substitute in to make the progression a little more advanced, but thats the basic one.
