As the chords of a 12-bar blues follow a form, so does the melodic line. The melodic line might just be the melody of the piece or it might also include lyrics. The melody and lyrics frequently follow an AA'B form, meaning one phrase is played then repeated (perhaps with a slight alteration), then something new is played. [14]
At its most basic, a single version of this blues scale is commonly used over all changes (or chords) in a twelve-bar blues progression. [7] Likewise, in contemporary jazz theory, its use is commonly based upon the key rather than the individual chord. [2] Greenblatt defines two blues scales, the major and the minor.
[36] [37] For example, a twelve-bar blues progression of chords in the key of E has three sets of four bars: E–E–E–E7 A–A–E–E B7–A–E–B7; this progression is simplified by playing the sevenths as major chords. [36] The twelve-bar blues structure is used by McCartney's "3 Legs", [32] which was noted earlier.

The Blues for Alice changes, Bird changes, Bird Blues, or New York Blues changes, is a chord progression, often named after Charlie Parker ("Bird"), which is a variation of the twelve-bar blues. The progression uses a series of sequential ii–V or secondary ii–V progressions, and has been used in pieces such as Parker's "Blues for Alice".
A common type of three-chord song is the simple twelve-bar blues used in blues and rock and roll. Typically, the three chords used are the chords on the tonic, subdominant, and dominant (scale degrees I, IV and V): in the key of C, these would be the C, F and G chords. Sometimes the V 7 chord is used instead of V, for greater tension.
It is a twelve-bar blues in 6 8; the chord sequence is that of a basic blues and made up entirely of seventh chords, with a ♭ VI in the turnaround instead of just the usual V chord. In the composition's original key of G this chord is an E ♭ 7. "All Blues" is an example of modal blues in G Mixolydian. [2] [clarification needed]
Steedman (1984) [1] has proposed a set of recursive "rewrite rules" which generate all well-formed transformations of jazz, basic I–IV–I–V–I twelve-bar blues chord sequences, and, slightly modified, non-twelve-bar blues I–IV–V sequences ("rhythm changes"). The typical 12-bar blues progression can be notated
