Scaruffi writes that jazz was always primarily an instrumental style, while blues was first and foremost vocal. Scaruffi notes that the main musical difference between jazz and blues is that jazz contains heavy syncopation, which was derived from ragtime music. Bill Dahl writes that blues music is technically defined by a I-IV-V chord sequence with a 12-bar motif. Herman adds that vocally, the blues is characterized by three-line rhymed stanzas with repeating verses. Flattening the third, fifth and seventh notes of the melody makes for a blues sound, Herman writes. With their distinct origins and geographies, the two musical styles developed their own stars. Scaruffi reports that the first jazz album was recorded by Edward "Kid" Ory and his Creole Orchestra. Early stars included Louis Armstrong, Jimmie Noone and George Lewis. In the 1950s and 1960s, legends like Miles Davis and John Coltrane became household names. The blues, in turn, boasted players such as Robert Johnson, who was known as "the King of Delta Blues," and Blind Lemon Jefferson. The Memphis band conductor W.C. Handy, and electric blues stars B.B. King and Howlin' Wolf, retain a vast influence over contemporary blues artists.
