The driving left-hand blues style known as boogie-woogie
appeared around 1900 It began to surface in saloons,
honky-tonks, bawdy houses, and "barrelhouses" in the
South and Midwest around 1912.
"Barrelhouse" became synonymous with boogie-woogie.
Music was generally supplied by a single pianist on an
instrument in a questionable state of repair. The strongest
possible expression of rhythm was therefore necessary,
and the boogie bass supplied it perfectly. Primitive, gutsy,
driving, it could be heard above the noise of the crowd and
would work, at least in some keys, if the piano was missing
a few keys.
Boogie-woogie spread more rapidly in the black community
in the 1920s, became a national fad from 1938 to about
1945, and then rapidly faded from view
