If someone were to invent a laughter-recording machine and use it in the theatre during farces the stage-managers would be amazed to find how often it happens that the noise of laughter made by two or three persons on the stage is greater than that made by the whole audience; whenever this occurs it is certain that a kind of irritation is being bred in the house for which someone has to suffer.
This is the sort of thing that happens. A character enters and announces that something very ludicrous has befallen another character, and proceeds to state what it is to the other persons in the scene, the statement being interrupted by his outbursts of laughter, and they in turn roar and hold their sides; yet often enough what is being told does not seem very amusing to us—even, perhaps, appears puerile—so we are vexed, and smile coldly at the piece and players. If the laughter on the stage were more moderate ours would not be the less, and we should feel more benevolent to the play and laugh with greater freedom if and when something funny took place.
The whole question of laughter is curious and difficult. There is one fairly constant first-nighter whose loud laughter upon insufficient provocation sometimes irritates the house, to the prejudice of the play; not long ago one of our young actresses laughed so immoderately, as a spectator, at trifles during a performance that some of the audience actually uttered inarticulate sounds, intended to suggest to her that she should be quieter.
Everybody knows the terrible people who laugh in a theatre at the wrong place, or indulge in the wrong kind of laughter, and are hilarious during pathetic passages, the pathos of which is heightened by touches of cruel humour. Some commit this crime from simple stupidity, not perceiving that the humour is tragic, not comic; others because they think that dignity of character is shown if they refuse to be moved by imaginary woes. The person is hateful who cannot shed an honest, if furtive, tear at a finely conceived and executed pathetic incident in a play, and the more if he is proud of his insensibility or lack of imagination; and we love an honest fellow who, like Jules Janin, wept "comme un veau" during La Dame aux Camellias. Such insensible creatures resemble "the man that hath no music in himself." Sometimes their conduct is so severely resented by audible protest that they are shamed into restraint.
It seems quite a long time since we have had a genuine debauch of hearty laughter in the theatre, of "Laughter holding both his sides." There has been a great deal of laughter, but it must be remembered that there are several kinds of laughter. So much difference exists between one species of laughter and another that the close observer can guess from the nature of the laughter in the theatre what is the sort of piece which provokes it.
No doubt the subject of laughter is one of great difficulty. On the point one may quote a passage from Darwin: "Many curious discussions have been written on the causes of laughter with grown-up persons. The subject is extremely complex ... laughter seems primarily to be the expression of mere joy or happiness. The laughter of the gods is described by Homer as 'the exuberance of their celestial joy after their daily banquet.'" This, perhaps, hardly agrees with the popular idea of the term "Homeric laughter."
It may be that in the phrases of Darwin one sees a key to the difference between the laughter at witty dialogue and the laughter caused by comic situation, the former being an expression of intellectual amusement, not necessarily accompanied by "mere joy or happiness," whilst the latter is to a great extent the outcome of simple, non-intellectual human pleasure. In the case of a witty comedy one hears ripples of laughter rather than waves, and they have no cumulative effect, one may even laugh during a great part of the evening without reaching that agony of laughter which comes from an intensely funny situation—in fact, each laugh at dialogue is to some extent independent of the others. In the case of a funny situation there is a crescendo, and sometimes each outburst of laughter begins at the highest point reached by the outburst before it, till an intense pitch is attained; and, in fact, there is really no complete subsidence at all till the top of the climax is arrived at, but one is chuckling in between every spasm.
The term "screamingly funny" has a real meaning; one reaches an almost screaming pitch that leads to something like physical exhaustion, and certainly causes an aching of the sides, and even tears.
Another quotation from Darwin: "During excessive laughter the whole body is often thrown backwards and shakes, or is almost convulsed; the respiration is much disturbed; the head and face become gorged with blood, with the veins distorted; and the orbicular muscles are spasmodically contracted in order to protect the eyes. Tears are freely shed." On this one may refer to a phrase by Sir Joshua Reynolds: "It is curious to observe, and it is certainly true, that the extremes of contrary passions are, with very little variation, expressed by the same action." Yet another passage from Darwin: "With Europeans hardly anything excites laughter so easily as mimicry, and it is rather curious to find the same fact with the savages of Australia, who constitute one of the most distinct races in the world."
Probably the enjoyment of the spectator simply as an animal is higher, if in a sense lower, when it comes from situations than when it is due to dialogue. Of course there is no sharp line of demarcation. One understands, however, why successful farce is more popular than a successful comedy, even if afterwards the audience suffer a little from aching sides; the ache itself causes a pleasurable memory.
