Probably the best place to start is with Bob Timmers' definition from the Rockabilly Hall Of Fame:
ROCKABILLY: WHAT IS IT?
Without saying "it's just a feeling", rockabilly is a hard term to pin down.
The simplest way may be to describe it as picturing an exciting blend of the blues, country and gospel sounds
of American music that were prevalent up to the mid-1950's.
Mix that in with the heavier beat that was becoming more and more a part of the pop music of the day, and the result was
"rock 'n' roll".
So what then is rockabilly?
Let's call it a window. Many young musicians found a sound that appealed to the ears and dancing feet of their generation.
The older generation stepped back in amazement. During the time frame of 1955-1960 a unique musical historical window
was created. "Rockabilly music" WAS THE WINDOW.
We will add some name recognition to help illustrate. We've all heard about Elvis' early "Memphis Sound"
on the Sun records? This sound captured teen hearts of the fifties and is still recognizable today.
Do any of these other names sound familiar? Ricky Nelson, Carl Perkins, Jerry Lee Lewis, Johnny Cash, Bill Haley & The Comets,
Roy Orbison, The Everly Brothers, Chuck Berry, Eddie Cochran, Buddy Holly and Gene Vincent.
These are just some of the names of rockabilly artists most people have heard.
These talents have been admired for over two generations.
Rockabilly is one of the purist forms of American roots music. It was never a watered-down, homogenized sound designed
by corporate record companies to build profits. You can't change something musical that is pure and simple without
ruining the result.
The writer of "Rock Around the Clock" was quoted as saying,
"It amazes me to this day, when I'm at a dance or party and 'Rock Around the Clock' is played,
six-year-old kids are jumping up and down and 85-year-old grandmas are tappin' their feet.
I don't believe they even realize why they're doing it. This sound and music has to be timeless!".
You'll have to admit that rockabilly, the "launching pad of rock 'n' roll", has become a major part of the current music scene as it often resurfaces in movies and in bits and pieces of today's songs. Just listen carefully, you'll hear it and love it.

Well, for us, the answer is partly historical, partly in the "feel" of the music, and partly in the instrumentation, and even then that's not the full answer!
