MEMPHIS, Tenn. — Scotty Moore, the pioneering rock guitarist whose sharp, graceful style helped Elvis Presley shape his revolutionary sound and inspired a generation of musicians that included Keith Richards, Jimmy Page and Bruce Springsteen, died Tuesday. He was 84.

Moore died at his home in Nashville, said biographer and friend James L. Dickerson, who confirmed the death through a family friend.

“As a musician, I consider him one of the co-founders of rock ‘n’ roll because of the guitar licks that he invented,” Dickerson said, calling Moore an icon.

Presley’s ex-wife Priscilla Presley echoed that sentiment in a statement Tuesday night: “Elvis loved Scotty dearly and treasured those amazing years together, both in the studio and on the road. Scotty was an amazing musician and a legend in his own right. The incredible music that Scotty and Elvis made together will live forever and influence generations to come.”

Moore, a member of the Rock and Roll Hall of Fame, was the last survivor of a combo that included Presley, bassist Bill Black and producer Sam Phillips.

Moore was a local session musician when he and Black were thrown together with Presley on July 5, 1954, in the Memphis-based Sun Records studios. Presley was a self-effacing, but determined teen anxious to make a record. Moore’s bright riffs and fluid solos — natural compliments to Presley’s strumming rhythm guitar — and Black’s hard-slapping work on a standup bass gave Elvis the foundation on which he developed a fresh blend of blues, gospel and country that came to be called rock ‘n’ roll.

For the now-legendary Sun sessions they covered a wide range of songs, from “That’s All Right” to “Mystery Train.” After “That’s All Right” began drawing attention, Presley, Moore and Black took to the road playing any gig they could find, large or small, adding drummer D.J. Fontana and trying their best to be heard over thousands of screaming fans.

The hip-shaking Presley soon rose from regional act to superstardom, signing up with RCA Records and topping the charts with “Heartbreak Hotel,” “All Shook Up” and many other hits. Elvis was the star, but young musicians listened closely to Moore’s contributions, whether the slow, churning solo he laid down on “Heartbreak Hotel” or the flashy lead on “Hard-Headed Woman.”

Moore, Black and Fontana backed Presley for his shocking TV appearances and early movies, but by 1957 had tired of what Moore called “Elvis economics.” In the memoir “That’s Alright, Elvis,” published in 1997, Moore noted that he earned just over $8,000 in 1956, while Presley became a millionaire. Moore also cited tension with Elvis’ manager, “Colonel” Tom Parker.

Moore worked one more time with Elvis, for the 1968 “comeback” TV special that helped return him to the top of the charts. But Moore’s compensation didn’t even cover his travel expenses, he would recall, and he was not asked to join Presley’s band for his tours in the 1970s. (Presley died in 1977).

Starting in the late 1950s, Moore worked on various projects. In 1959, singer Thomas Wayne had a Top 5 hit, “Tragedy,” on Moore’s Fernwood record label. Moore put out a solo album in 1964 called “The Guitar That Changed the World!” and with Fontana played on the 1997 Presley tribute album “All the King’s Men,” featuring Richards, Levon Helm and other stars. He and Fontana also backed Paul McCartney for the ex-Beatle’s cover of “That’s All Right.” In 2000, Moore was inducted into the Rock Hall of Fame. More recently, he was a recording studio manager, engineer and businessman.

“He was a class act as a human being,” biographer Dickerson told The Associated Press late Tuesday. “Besides being one of the best guitarists that ever lived and most inventive, he was a great person, and you don’t always find that in the music industry.”
