Rock'n'Roll

Rock'n'roll originates from US in the late 4o's and it become famous in the 40's. The music style during that period usually contained saxophones and piano sound, which later in the 50's replaced by electric guitars.
So the Rock n roll had the same  rythm as blues, with the same drum kit and usually a couple of guitars, a lead and a rythm.This gerne is mostly a dancing one, and sometimes people confused its sound with Hard rock's one from bands like Motorhead.
