Rock music is a genre of Pop music (popular music) which has its roots in 1940’s and 1950’s, being heavily influenced by Rhythm and Blues (R&B). Rock ‘n’ roll was the earliest form of rock music which originated in the USA; though some elements of rock n roll can be heard in records from 1930s, rock ‘n’ roll was not then popular and did not acquire its name until the 50s. In rock n roll music, either the piano or saxophone was often the lead instrument, but these were generally replaced or supplemented by guitar and is almost always provided by a snare drum. Rock music developed in 1960’s, particularly because the UK also produced bands, like the Beatles, which contribution to the rock industry. It has been redefined and reinvented itself which caused a number of distinct rock music sub-genres to emerge.
