The Root of Everything

The blues emerged from the experience of African Americans in the Deep South after the Civil War — a fusion of work songs, field hollers, spirituals, and African musical traditions. It was music born from suffering and resilience, and its emotional directness became the template for all popular music that followed.

The standard 12-bar blues structure (I-I-I-I, IV-IV-I-I, V-IV-I-I) is the most influential chord progression in music history. Rock, jazz, country, R&B, and pop all descend from this pattern. Robert Johnson, who recorded only 29 songs before dying at 27, created a guitar style so advanced that listeners swore two players were performing at once.
