Beat! beat! drums!—blow! bugles! blow!
Through the windows—through doors—burst like a ruthless force,
Into the solemn church, and scatter the congregation,
Into the school where the scholar is studying;
Leave not the bridegroom quiet—no happiness must he have now with
his bride,
Nor the peaceful farmer any peace, ploughing his field or gathering
his grain,
So fierce you whirr and pound you drums—so shrill you bugles blow.
—Beat! Beat! Drums!, Walt Whitman
