lowest of them, on the stage, is at least a general, a captain of the guards, or some such personage. All the airs should be formed of the same materials--long divisions, holding notes, and repetitions of insignificant words, as amore, amore, impero, impero, Europa, Europa, furori, furori, orgoglio, orgoglio, &c.; and therefore the composer should have before him a memorandum of the things necessary for the termination of every air. This will enable him to eschew variety, which is no longer in use. After ending a recitative in a flat key, he will suddenly begin an air in three or four sharps; and this by way of novelty. If the modern composer wishes to write in four parts, two of them must proceed in unison or octave, only taking care that there shall be a diversity of movement; so that if the one part proceeds by minims or crotchets, the other will be in quavers or semiquavers. He will charm the audience with airs, accompanied by the stringed instruments _pizzicati_ or _con sordini_, trumpets, and other effective contrivances. He will not compose airs with a simple bass accompaniment, because this is no longer the custom; and, besides, he would take as much time to compose one of these as a dozen with the orchestra. The modern composer will oblige the manager to furnish him with a large orchestra of violins, oboes, horns, &c., saving him rather the expense of double basses, of which there is no occasion to make any use, except in tuning at the outset. The overture will be a movement in the French style, or a prestissimo in semiquavers in a major key, to which will succeed a _piano_ in the minor; concluding with a minuet, gavot or jig, again in the major key. In this manner the composer will avoid all fugues, syncopations, and treatment of subjects, as being antiquated contrivances, quite banished from modern music. The modern composer will be most attentive to all the ladies of the theatre, supplying them with plenty of old songs transposed to suit their voices, and telling each of them that the Opera is supported by her talent alone. He will bring every night some of his friends, and seat them in the orchestra; giving the double bass or violoncello (as being the most useless instruments) leave of absence to make room for them.
