It's hard to define blues. On a literal angle, it's the dance you do to blues music, generally involving lots of improvisation, closeness, and hip movements. While swing and blues have basics, frames, and moves... blues doesn't.
Blue notes (or worried notes), usually thirds or fifths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove. Blues as a genre is also characterized by its lyrics, bass lines, and instrumentation. Early traditional blues verses consisted of a single line repeated four times.
