Which early style of blues was characterized by the use of harmonica and guitar? Delta blues

New York blues

Delta blues: one of the earliest styles of blues. Originating around the Mississippi delta, this style is dominated by slide guitar and harmonica, usually with passionate vocals and deeply personal lyrics. Delta blues gave rise to Chicago and Detroit blues. Recordings are mostly one person singing and playing, while live shows involved bands more often. However, bands were minimal, usually bass and light drums.
