Droning a drowsy syncopated tune,
Rocking back and forth to a mellow croon.
I heard a Negro play.
Down on Lenox Avenue the other night
By the pale dull pallor of an old gas light
He did a lazy sway….
He did a lazy sway….
To the tune o’ those Weary Blues.
With his ebony hands on each ivory key
He made that poor piano moan with melody.
O Blues!
Swaying to and fro on his rickety stool
He played that sad raggy tune like a musical fool.
Sweet Blues!
Coming from a black man’s soul.
