Blues originated in African American slaves in the southern United States.
=== Alternative Theory ===
The other common blue note is the flattened flatted 5th, and this does not make as much sense in terms of the theory above. The equal temperament 5th is actually very slightly below the just intonation fifth. Thus, there is no need to use the flattened flatted 5th to get "below" the just intonation 5th; and because the just and equal temperament notes are so close already, there is no need for a blue note. And to add complexity to the matter, the equal temperament diminished 5th is actually quite higher than the just intonation flattened flatted 5th.
Furthermore, the blue notes can only be bent upwards towards their just intonation counterparts on instruments that allow notes to be bent. For piano and many other instruments, this is not possible.
The common minor blues scale is the same as the minor pentatonic scale, plus the d5/a4/tt between the 4th and 5th. It is seen as the D# in the A blues scale below.
A C D D# E G A C D D# E G A C
The last 4 bars are often called the turnaround, involving the V - IV - I or V - IV - I - V progression, which leads back into the beginning of the entire 12 bar progression. The V - IV - I progression is called the ''Blues Turnaround''.
=== Blues Shuffle ===
Rather than simply playing sustained chords or strumming patterns, blues would often use a ''shuffle'' to indicate the harmony. This consists of alternating between P5, M6, and m7 intervals, almost like a riff, often employing some sort or swing feel.

Other simpler versions using just a bassline deliver the same meaning:
