Moore is given credit as a pioneer rock 'n' roll lead guitarist, though he characteristically downplayed his own innovative role in the development of the style. "It had been there for quite a while", recalled Moore. "Carl Perkins was doing basically the same sort of thing up around Jackson and I know for a fact Jerry Lee Lewis had been playing that kind of music ever since he was ten years old." Paul Friedlander describes the defining elements of rockabilly, which he similarly characterizes as "essentially ... an Elvis Presley construction": "the raw, emotive, and slurred vocal style and emphasis on rhythmic feeling the blues with the string band and strummed rhythm guitar [of country". In "That's All Right", the Presley trio's first record, Moore's guitar solo, "a combination of Merle Travis–style country finger-picking, double-stop slides from acoustic boogie and blues-based bent-note, single-string work, is a microcosm of this fusion."
