Theory

In the blues, all three primary chords (I, IV, and V) are dominant sevenths — unlike classical or pop harmony where only V is dominant. This creates a unique harmonic world where there is no "home" chord that feels fully resolved — everything has the slight tension of a dominant seventh. The I7, IV7, and V7 create a three-chord story: the I7 is home (but tense), the IV7 moves away, and the V7 creates the strongest push back to I7. The 12-bar form traditionally goes: I7 (4 bars) – IV7 (2 bars) – I7 (2 bars) – V7–IV7–I7 (2 bars). The blues scale and minor pentatonic fit perfectly over all three chords. In C major: C7 – F7 – G7 – F7.

Musical Meaning

The 12-bar blues (I7–IV7–V7) is the backbone of blues, rock, and jazz. All three chords are dominant sevenths, so the whole progression exists in a state of tension. That perpetual unresolved feeling IS the blues — raw, honest, and immediate.
