Which approach to playing the hammond organ was unprecented in gospel music?

Jimmy Smith's approach to playing the Hammond organ was unprecedented in gospel music. He incorporated elements of jazz and blues into his playing, creating a unique and exciting style that set him apart from other gospel organists. Smith's use of the organ's bass pedals and his ability to improvise on the spot were particularly influential, and his playing helped to popularize the Hammond organ as a lead instrument in gospel music.
