The 12 Bar Blues
The name 12 Bar Blues comes from the number of measures or
bars in most blues songs - twelve. Here's the basic 12 bar blues
(Chicago blues) in the key of A.
Blues musicians often refer to chord changes by Roman numerals
after the steps of the scale. Below are the scale steps in the
key of A and the chords associated with them.
I A (the key of the song) II Bmi III C#mi IV D V E VI F#mi VII G#dim
Blues and the I, IV, V Chords
Many blues songs have just three chords, the I, IV and V chords.
In the key of A, that's A, D and E. Here's Further On Up the
Road by chord name and Roman numerals.
/ I / IV / I / I / IV / IV / I / I /

The
Turnaround
1) The last 2 bars of the song are called the turnaround.
The basic turnaround is
... / A7 / E7 /
2) There are many varations of the turn around. Here's a
common one
... / A7 D7 / A7 E7 /
Eight Bar Blues
Key to the Highway - uses the turnaround variation (#2
above)
/ A7 / E7 / D7 / D7 / A7 / E7 / A7 D7 / A7 E7 /
/ I / V / IV / IV / I / V / I IV / I V
/
Minor Blues
/ Am / Am / Am / Am / Dm / Dm / Am / Am / Em / Dm / Am / - /
/ I / I / I / I / IV / IV / I
/ I / V / IV / I / - /
A minor 12 bar blues usually has a repeated rhythm pattern and
no chord in the 12 measure.
Take It Down From The Fifth
The chord number system comes in handy on a gig. If the band
leader says "take it down from the fifth", that means start the
song from V chord in the 9th measure.
... / E7 / D7 / A7 / E7 /
... / V / IV / I / V /
And if someone points at you and holds up 4 fingers, it means
play the IV chord now!
Bridge (B part of song)
Some blues songs have a "B" part or bridge. You'll find this one
in many songs.
/ D7 / A7 / D7 / A7 / D7 / A7 / B7 / E7 /
/ IV / I / IV / I / IV / I / II / V /
The 'unexpected' "IV" chord (instead of the I chord) creates
tension and interest. Usual format - AABA.
The Blues had a baby and they called it Rock N Roll. A
