Camille D'Arville has temperament, and she has style. It is these two qualities particularly that have brought her success so often in dashing cavalier parts, parts which require that a woman shall act either a man or a woman masquerading as a man. The modern comic opera librettist often has but one main purpose in mind, that is, to get his prima donna in tights as soon after the show begins as possible and keep her in them as long as practical. Indeed, if one were looking for a practical way to distinguish modern comic opera from extravaganza, he might find it in this matter of tights. If the leading woman represent a woman disguised as a man, she is an operatic prima donna; if, on the contrary, she be represented as a man from start to finish, she is merely principal "boy" in extravaganza. I suppose this tendency toward tights, which is so common as to be almost a light-opera conventionality, is an outgrowth or heritage from the old-fashioned burlesque. In fact, the difference between the modern comic opera and the burlesque of thirty years ago is purely one of degree. The relation between the two is similar to that between the variety show of eight years ago and the so-called "fashionable vaudeville" of to-day. Variety has been put through what managers of the large circuits call a refining process. There is no denying that the old-style variety show in most of its components was crude, noisy, and vulgar, and that its surroundings were scarcely favorable to the development of high art. But one was always sure of finding vigor and life--plenty of both--in the old-time varieties, and there were oftentimes spontaneity and humor--rude and bucolic, perhaps, but real, just the same--which one is not sure of meeting in the latter-day entertainments so carefully prepared for the mentally delicate and sensitive. Modern comic opera has adopted in a modified and refined form the chief characteristics--one of them the woman in tights and another of them the clown with his perfunctory low comedy--of the old-fashioned burlesque. Of course, the opera makes more pretensions than did the burlesque, and musically it is superficially superior, not necessarily more tuneful but orchestrated with more scholarly skill. Stage pageantry to-day is also much further developed, and spectacular effects are far more elaborate. The costuming is richer and more tasteful, and the women on the stage--if not actually younger and prettier--are certainly daintier and more feminine. The girlishness and natural beauty of many modern light-opera choruses are simply amazing.
