Chuck Berry, one of the founding fathers of Rock and Roll, described the rock and roll family tree with a great quote about Rock’s origins:
“The Blues had a baby.  They call it Rock and Roll”.

It’s clear that Rhythm and Blues is Rock’s closest relative, but as it grew, influences from many different genres found their way in.

Country Music

Some of Rock’s most influential ancestors fall in the space somewhere in between Country Music and Rhythm and Blues. Music historians list several sub-genre in here, including Western Swing, Hillbilly Blues, Honky Tonk, and Bluegrass.

Rockabilly

Early in the history of Rock, the country / blues combination was combined with early Rock. The result was Rockabilly, and it brought the first major wave of popularity to the Rock craze. Elvis’ 1954 recording of “That’s Alright Mama” started it off, and Bill Haley’s “Rock Around The Clock” spread Rock’s musical influence around the world.

Gospel

Over the years, Rock has borrowed heavily from Gospel, most notable in the harmonies. Many of the early stars credit their church and Gospel music for their musical training.

Teen Idols

“Sex sells” is the old advertising slogan and it proved itself in the early history of Rock. Elvis, of course, started it off with his “Elvis the Pelvis” stage appearance, but after Rock’s initial burst of popularity, the buzz faded. All of a sudden, there were no stars. Buddy Holly, Ritchie Valens, and the Big Bopper (J.P. Richardson) were killed in a plane crash, Elvis was in the army, Chuck Berry was in jail, Jerry Lee Lewis had shocked even the liberal rockers by marrying his underaged cousin, and Alan Freed had been convicted in the Payola scandal.

When the Winter Dance Party Tour (Buddy Holly’s tour with Richie Valens and The Big Bopper) resumed, it included three clean cut, all american teenage heartthrobs. Jimmy Clanton, Frankie Avalon, and Robert Velline (Bobby Vee) sang soft rock love songs and rocketed to stardom. They were followed by Neil Sedaka, Bobby Vinton, and the California beach singers like the Beach Boys and Jan & Dean.
