…rock and roll…is music that anyone can play (or can imagine playing) and everyone can dance to. The learning curve for performing the stuff is short; the learning curve for appreciating it is nonexistent. The instrumentation and the arrangements are usually simple: three or four instruments and, frequently, about the same number of chords. You can add horns and strings and backup singers, and you can add a lot more chords, but the important thing is the feeling. Rock and roll feels uninhibited, spontaneous, and fun. There’s no show-biz fakery coming between you and the music. As with any musical genre, it boils down to a certain sound. Coming up with that sound, the sound of unrehearsed exuberance, took a lot of work, a lot of rehearsing.
