[1] i know what the caged bird feels, alas! when the sun is bright on the upland slopes; when the wind stirs soft through the springing grass, and the river flows like a stream of glass; [5] when the first bird sings and the first bud opes, and the faint perfume from its chalice steals— i know what the caged bird feels! i know why the caged bird beats his wing till its blood is red on the cruel bars; [10] for he must fly back to his perch and cling when he fain would be on the bough a-swing; and a pain still throbs in the old, old scars and they pulse again with a keener sting— i know why he beats his wing! [15] i know why the caged bird sings, ah me, when his wing is bruised and his bosom sore,— when he beats his bars and he would be free; it is not a carol of joy or glee, but a prayer that he sends from his heart's deep core, [20] but a plea, that upward to heaven he flings— i know why the caged bird sings!
