On the Sublime and Beautiful/Part II/Chapter 19

A SUDDEN beginning or sudden cessation of sound of any considerable force, has the name power. The attention is roused by this; and the faculties driven forward, as it were, on their guard. Whatever, either in sights or sounds, makes the transition from one extreme to the other easy, causes no terror, and consequently can be no cause of greatness. In everything sudden and unexpected, we are apt to start; that is, we have a perception of danger, and our nature rouses us to guard against it. It may be observed that a single sound of some strength, though but of short duration, if repeated after intervals, has a grand effect. Few things are more awful than the striking of a great clock, when the silence of the night prevents the attention from being too much dissipated. The same may be said of a single stroke on a drum, repeated with pauses; and of the successive firing of cannon at a distance. All the effects mentioned in this section have causes very nearly alike.
