The blues is mostly about the blues scale, 12 bars and the I-IV-V chord progression. Most blues boils down to these three elements - most, but not all. There are so many sub-genres in Blues, it is difficult to name them all, but suffice it to say the R&B, Rock-n-Roll and Soul music are the direct descendants of the blues. There is also Jump Blues, Delta Blues, Piedmont Blues, Chicago Blues, Memphis Blues, Urban/Electric Blues, Zydeco and many more sub-genres that all relate to blues styling.
