Rock

POA

Rock band (or rock group) is a generic name to describe a group of musicians specializing in a particular form of electronically amplified music. Deriving its name from the musical style which was its immediate progenitor, rock and roll, the type of music played by rock groups has its roots deeply steeped in both rock and roll, and its immediate forebear, rhythm and blues.

Classic rock and roll is played with one electric guitar or two electric guitars (one lead, one rhythm), a string bass or (after the mid-1950s) an electric bass guitar, and a drum kit. In the earliest rock and roll styles of the late 1940s and early 1950s, either the piano or saxophone was often the lead instrument, but these were generally replaced or supplemented by guitar in the mid to late 1950s. The beat is essentially a boogie woogie blues rhythm with an accentuated backbeat, the latter almost always provided by a snare drum.

The massive popularity and eventual worldwide scope of rock and roll gave it an unprecedented social impact. Far beyond simply a musical style, rock and roll, as seen in movies and in the new medium of television, influenced lifestyles, fashion, attitudes, and language. It later spawned the various sub-genres of what is now called simply 'rock music'.
