The blues is an impulse to keep the painful details and episodes of a brutal experience alive in one's aching consciousness, to finger its jagged grain, and to transcend it, not by the consolation of philosophy but by squeezing from it a near-tragic, near-comic lyricism. As a form, the blues is an autobiographical chronicle of personal catastrophe expressed lyrically.
Ralph EllisonEvery serious novel is, beyond its immediate thematic preoccupations, a discussion of the craft, a conquest of the form, a conflict with its difficulties and a pursuit of its felicities and beauty.
