It's the Pulse

The pulse is rising to take this world to level enriched with varieties of tones and beats. The sound of rock is traditionally centered around the electric guitar, which emerged in its modern form in the 1950s with the popularization of rock and roll. The sound of an electric guitar in rock music is typically supported by an electric bass guitar pioneered in jazz music in the same era, and percussion produced from a drum kit that combines drums and cymbals. This trio of instruments has often been complemented by the inclusion of others, particularly keyboards such as the piano, Hammond organ and synthesizers.
