Blues music is relatively well recognised as a cultural phenomenon. In tracing its history, both as a reflection of one people's particular circumstances of oppression and as an ingredient taken into mainstream popular art, we accumulate reasons for thinking of it as important. But these are external reasons. It is possible to know that one's everyday milieu is heavily indebted to blues (in manners as well as in music), even to feel blues quality strongly, and yet not be able to articulate an understanding of the import of blues. In that case one is kept from thinking well about how the meaning of blues in, say, the life of an early twentieth-century black Mississippian relates to the meaning of blues in other sorts of life, including yours and mine today – which is precisely the inside of the cultural phenomenon of blues. To get over this hump we need to pay a kind of attention that blues rarely receives.
