Blues chord progressions: dominant harmony that moves by feel and function.
Blues often treats I, IV and V as dominant-family chords instead of using a purely diatonic major-key system. That gives the style its characteristic mixture of major, minor and dominant color.

The 12-bar form gives the blues its harmonic frame.
The exact chords and substitutions can vary, but the listener usually hears a large-scale movement from I toward IV, back to I, then through V before the turnaround.

Why blues harmony behaves differently from a normal major key.
The coexistence of major and minor thirds, dominant sevenths and pentatonic language is not a mistake to be corrected. It is part of the style.
Dominant tonic
The I chord can be I7 without functioning like a classical V chord. It is a stable blues tonic with dominant color.
Minor-pentatonic language
Minor pentatonic and blues-scale phrasing can sit convincingly over dominant-family chords because the style welcomes the tension between minor and major color.
Jazz-blues substitutions
ii–V motion, diminished passing chords and secondary dominants can enrich the 12-bar form while the large-scale blues structure remains recognizable.
Compact guitar movement
Small dominant voicings and upper-structure movement can create a more connected blues progression than jumping between full barre shapes.

What chords are used in a basic 12-bar blues?
A basic blues uses the I, IV and V chords, often as dominant sevenths. In C that gives C7, F7 and G7.
Why is the tonic chord dominant in blues?
Blues harmony uses dominant-seventh color as part of the tonic sound itself. It does not have to function as a classical dominant that resolves to another key.
Can jazz ii–V progressions be added to blues?
Yes. Jazz blues commonly adds ii–V motion, secondary dominants and turnarounds while keeping the underlying 12-bar form recognizable.
