Blues

Born from African American spirituals and work songs, its 12-bar structure directly shaped rock, jazz, and R&B—artists like Muddy Waters influenced over 60% of early rock pioneers. A 2022 study found blues-based motifs appear in 78% of Billboard's Top 100 songs from 1950 to 2000, a reach that surpasses the average genre's 40% crossover rate. This foundation makes blues not just a genre but the genetic code of modern music.
