In music, an eight-bar blues is a typical blues chord progression, "the second most common blues form," "common to folk, rock, and jazz forms of the blues," taking eight 4
4 or 12
8 bars to the verse.
Examples include "Sitting on Top of the World" and "Key to the Highway", "Trouble in Mind" and "Stagolee". "Heartbreak Hotel", "How Long Blues", "Ain't Nobody's Business", "Cherry Red", It Hurts Me Too, Worried Life Blues, and "Get a Haircut" are all eight-bar blues standards.
One variant using this progression is to couple one eight-bar blues melody with a different eight-bar blues bridge to create a blues variant of the standard 32-bar song. "Walking By Myself", "I Want a Little Girl" and "(Romancing) In The Dark" are examples of this form. See also blues ballad.
