Origins of the 12-Bar Blues

The exact origins of the 12-bar blues progression remain shrouded in mystery, with various theories attributing its inception to different regions and musical traditions. One widely accepted theory traces its roots back to African musical traditions brought to the Americas during the Trans-Atlantic slave trade.

These African musical forms, characterized by their call-and-response structure and repetitive rhythms, laid the groundwork for the development of early blues music. As African Americans began to express their experiences and struggles through music, the 12-bar blues emerged as a natural fit, providing a concise and expressive format to convey their emotions.
