Bar (music)
In musical notation, a bar is a segment of time defined by a given number of beats of a given duration.

, though they often come in threes, do not coincide with the above three lines or sections. This overlap between the grouping of the accompaniment and the vocal is part of what creates interest in the twelve bar blues.

Variations

"W.C. Handy, 'the Father of the Blues,' codified this blues form to help musicians communicate chord changes."(Alfred Publishing, 18) However, many variations are possible. The length of sections may be varied creating Eight-bar blues or Sixteen-bar blues.

In the original form the dominant chord continued through the tenth bar; later on the V-IV-I-I "shuffle blues" pattern became standard in the third set of four bars (Tanner and Gerow 1984, 37 cited in Baker 2004: "This alteration [V-IV-I rather than V-V-I] is now considered standard. (Tanner 37)."):

The common quick to four or quick-change (quick four(Alfred 2003, p. 4)) variation uses the subdominant chord in the second bar:

A seventh chord is a chord consisting of a triad plus a note forming an interval of a seventh above the chord's root. When not otherwise specified, a "seventh chord" usually means a major triad with an added minor seventh...

When the last bar contains the dominant, that bar may be called a turnaround
Turnaround (music)
In jazz, a turnaround is a passage at the end of a section which leads to the next section. This next section is most often the repetition of the previous section or the entire piece or song...
