(1) One at least is obvious, and indeed it is followed not merely during the conflict but from beginning to end of the play. There are, of course, in the action certain places where the tension in the minds of the audience becomes extreme. We shall consider these presently. But, in addition, there is, all through the tragedy, a constant alternation of rises and falls in this tension or in the emotional pitch of the work, a regular sequence of more exciting and less exciting sections. Some kind of variation of pitch is to be found, of course, in all drama, for it rests on the elementary facts that relief must be given after emotional strain, and that contrast is required to bring out the full force of an effect. But a good drama of our own time shows nothing approaching to the _regularity_ with which in the plays of Shakespeare and of his contemporaries the principle is applied. And the main cause of this difference lies simply in a change of theatrical arrangements. In Shakespeare's theatre, as there was no scenery, scene followed scene with scarcely any pause; and so the readiest, though not the only, way to vary the emotional pitch was to interpose a whole scene where the tension was low between scenes where it was high. In our theatres there is a great deal of scenery, which takes a long time to set and change; and therefore the number of scenes is small, and the variations of tension have to be provided within the scenes, and still more by the pauses between them. With Shakespeare there are, of course, in any long scene variations of tension, but the scenes are numerous and, compared with ours, usually short, and variety is given principally by their difference in pitch. It may further be observed that, in a portion of the play which is relatively unexciting, the scenes of lower tension may be as long as those of higher; while in a portion of the play which is specially exciting the scenes of low tension are shorter, often much shorter, than the others. The reader may verify this statement by comparing the First or the Fourth Act in most of the tragedies with the Third; for, speaking very roughly, we may say that the First and Fourth are relatively quiet acts, the Third highly critical. A good example is the Third Act of _King Lear_, where the scenes of high tension (ii., iv., vi.) are respectively 95, 186 and 122 lines in length, while those of low tension (i., iii., v.) are respectively 55, 26 and 26 lines long. Scene vii., the last of the Act, is, I may add, a very exciting scene, though it follows scene vi., and therefore the tone of scene vi. is greatly lowered during its final thirty lines.
