A dramatist, proportioning his rough story for performance in the limited space of time the stage permits, faces at once the question: “How many acts?” If inexperienced, noting the number of changes of set his story seems to demand he finds himself in a dilemma: to give an act to each change of scene is to break the play into many scrappy acts of a few minutes each; to crowd all his needed scenes into five acts is to get scenes as scrappy as the eight which make the fifth act of Shakespeare’s Macbeth or the ten in Act IV of Henry VI, Part II. In either case, if he gives his numerous scenes adequate treatment, he is likely to find their combined length forces him beyond the time limit the theatre allows—about two hours and a half.
Let him rid himself immediately of any feeling that custom or dramatic dignity calls for any preference among three, four, or five acts. The Elizabethan drama put such a spell upon the imagination of English-speaking peoples that until recently the idea was accepted: “Five is dignity, with a trailing robe, whereas one, two, or three acts would be short skirts, and degrading.”[1] Today a dramatist may plan for a play of three, four, or five acts, as seems to him best.
Why, if no change of scene be required, is not a play of one long act desirable? At first sight, there would seem to be a gain in the unbroken movement. The power of sustained attention in audiences is, however, distinctly limited. Any one who has seen a performance of The Trojan Women[2] by Euripides, or von Hofmannsthal’s Electra[3] needs no further proof that though each makes a short evening’s entertainment it is exhausting because of uninterrupted movement from start to finish. To plays of one long act most audiences become unresponsive from sheer physical fatigue. Consequently, use has confined one-act plays to subjects that may be treated in fifteen minutes to an hour, with an average length of from twenty to forty-five minutes. Strindberg has stated well the problem which the play in one long act involves: “I have tried,” he wrote in his Introduction to Miss Julia, “to abolish the division into acts. And I have done so because I have come to fear that our decreasing capacity for illusion might be unfavorably affected by intermissions during which the spectator would have time to reflect and to get away from the suggestive influence of the author-hypnotist. My play will probably last an hour and a half, and as it is possible to listen that length of time, or longer, to a lecture, a sermon, or a debate, I have imagined that a theatrical performance could not become fatiguing in the same time. As early as 1872, in one of my first dramatic experiments, The Outlaw, I tried the same concentrated form, but with scant success. The play was written in five acts, and wholly completed, when I became aware of the restless, scattered effect it produced. Then I burned it, and out of the ashes rose a single, well-built act, covering fifty printed pages, and taking an hour for its performance. Thus the form of the present play is not new, but it seems to be my own, and changing aesthetical conventions may possibly make it timely.
“My hope is still for a public educated to a point where it can sit through a whole-evening performance in a single act. But that point cannot be reached without a great deal of experimentation.”[4]
The difficulty with a play of only two acts is similar. If the piece is to fill an evening, each act must last an hour or more. The Winter’s Tale is really a two-act play: Act I is the story of Hermione and Leontes, Act II the story of Florizel and Perdita, with Time as Chorus separating the acts. Division of this play into five acts and use of modern scenery have given it the effect of breaking to pieces midway, where Time speaks. When each of the two parts is played uninterruptedly, as in Mr. Granville Barker’s recent revival, this effect disappears and it becomes clear that the original division is artistically right. However, so long is each of the two parts that The Winter’s Tale, when seen in this way, badly strains the attention of a present-day audience.
Contrastingly, to use more than five acts in the space of two hours and a half is either to carry the performance over into a second day, as with the two-part play of Elizabeth’s time—something we cannot now tolerate; or to write such scrappy acts that the frequent shifting of scenery and dropping of the curtain spoil desired illusion. If it be remembered that there is nothing essentially wrong in a play of one, two, six, or even more acts, and that changing tastes or the necessities of particular subjects may in very rare instances make any of these divisions desirable, it can be said that three, four, or five acts are today the normal divisions for plays.
An objection to long plays of one or two acts is that when the piece lasts only an hour and a half, as in the case of Miss Julia, the evening must be filled out with something else. In the first place, it is by no means easy to arrange a mixed program in which each play shows to complete advantage. Nor are audiences usually fond of adjusting themselves to new characters and new plots two or three times in an evening. On the professional stage, Barrie’s short plays have done something to make the general public more ready to shift their interest to fresh subjects in the course of an evening, but a mixed program of plays is rarely popular except in theatres of the so-called “experimental” class.
The advantage in three acts is that each allows a longer space than does the division into four or five acts in which characterization may develop before the eyes of the audience, or a larger number of illustrative actions bearing on the central purpose of the act may be shown. The offset is that three acts provide only two breaks by which the passing of time may be suggested. Neither four nor three acts have any essential superiority over each other, or over five acts. Five acts, in and of themselves, have no superiority over four or three; nor, as some persons have seemed to think, are they the only divisions in which a drama in verse may be written. Avoidance of awkward changes of scene within an act may compel use of four or five acts rather than three. The more episodes in the story to be dramatized, the more aspects of character to be shown by action, the more acts or scenes the dramatist must use. If long spaces of time must be allowed for because they are part of the story or marked changes of character demand them, the dramatist will need more entr’acte space, and, consequently, more acts. It is, then, necessary change of place and passage of time which are the chief factors in determining choice among three, four, or five acts.
For centuries theoretical students of the drama have worried themselves about the two unities: place and time. Practising dramatists, however, have usually found that generalizations in regard to them help little and that in each individual play they must work out the place and time problems for themselves. Practice as to shifting scenes has depended most, and always will, upon whether the physical conditions of the stage permit many real or imagined shifts. The Greek stage, with its fixed background and its chorus nearly always present, forced an attempt at unity of place, though the Greeks often broke through it.
