I need about how Elvis changed Rock and Roll?

Ok a few friends and I are doing a project about how Elvis changed Rock and Roll. I already know that he had a different type of music however if you know any additional information that would be greatly appreciated. Otherwise just a good website about it would help and not just about elvis in general. If your just doing this for the points then your not helping so please just answer if you know things about elvis. Thank you for people who are actually helping.|||He changed and made rock n roll just new!





He had used three types of backbeats for his music.. Those backbeats were of:-





Blues.


Gospel.


Country.





With it's fusion, he made rock n roll.





Rockabilly is different thing.. Yes it is 100% clear that Elvis invented it, but it's different.. He had used three types of backbeats here too, but bit different. Those backbeats were of:-





Rhythm and blues


Hillbilly music


Country





Hope it helped you.|||He was a white man, singing black mans music! He was doing dance moves that Ed Sulivan banned on his show, they kept the camera above his waist.





He was a rebel of his time.|||This might help you

As an example, take Elvis' cover of "Guitar Man." That song was written by country guitar great Jerry Reed. Not only that, but Jerry Reed even played guitar on Elvis' version since Elvis' guitarist couldn't play like Jerry Reed (finger picking kind of playing).





Oh, and I'd consider Elvis more rockabilly than rock and roll.|||HE DID NOT IMPROVE HE MADE ROCK N ROLL AHAH IDK?
