This is a study of the Cha-cha-cha groove originated in Cuba and used by Muddy Waters in the head of later versions of his song, “Walking Thru The Park.” Slim Harpo’s “Buzzin” and Junior Wells’s “Cha Cha Cha in Blue” are other recorded songs using this type of riff driven groove. Remember that this groove is not a shuffle or swing. It is a straight eight note groove. Always use Tongue Blocking.
