Wars and rumours of wars stunted musical development of all kinds in Germany during the earlier years of the eighteenth century. After the death of Keiser in 1739, the glory departed from Hamburg, and opera seems to have lain under a cloud until the advent of Johann Adam Hiller (1728-1804), the inventor of the Singspiel. Miller's Singspiele were vaudevilles of a simple and humorous description interspersed with music, occasionally concerted numbers of a very simple description, but more often songs derived directly from the traditions of the German Lied. These operettas were very popular, as the frequent editions of them which were called for, prove. Yet, in spite of their success, it was felt by many of the composers who imitated him that the combination of dialogue and music was inartistic, and Johann Friedrich Reichardt (1752-1814) attempted to solve the difficulty by relegating the music to a merely incidental position and conducting all the action of the piece by means of the dialogue. Nevertheless the older form of the Singspiel retained its popularity, and, although founded upon incorrect æsthetic principles—for no art, however ingenious, can fuse the convention of speech and the convention of song into an harmonious whole—was the means in later times of giving to the world, in 'Die Zauberflöte' and 'Fidelio,' nobler music than had yet been consecrated to the service of the stage.
CHAPTER IV
MOZART
Although Mozart's (1756-1791) earliest years were passed at Salzburg, the musical influences which surrounded his cradle were mainly Italian. Salzburg imitated Vienna, and Vienna, in spite of Gluck, was still Italian in its sympathies, so far at any rate as opera seria was concerned. Mozart wrote his first opera, 'La Finta Semplice,' for Vienna, when he was twelve years old. It would have been performed in 1768 but for the intrigues of jealous rivals and the knavery of an impresario. It was not actually produced until the following year, when the Archbishop of Salzburg arranged a performance of it in his own city to console his little protégé for his disappointment at Vienna. It is of course an extraordinary work when the composer's age is taken into account, but intrinsically differs little from the thousand and one comic operas of the period, Mozart's first German opera, 'Bastien und Bastienne,' though written after 'La Finta Semplice,' was performed before it. It was given in 1768 in a private theatre belonging to Dr. Anton Meszmer, a rich Viennese bourgeois. It follows the lines of Miller's Singspiele closely, but shows more originality, especially in the orchestration, than 'La Finta Semplice.' The plot of the little work is an imitation of Rousseau's 'Devin du Village,' telling of the quarrels of a rustic couple, and their reconciliation through the good offices of a travelling conjurer. It was significant that the Italian and German schools should be respectively represented in the two infant works of the man who was afterwards to fuse the special beauties of each in works of immortal loveliness. Mozart's next four operas were, for the most part, hastily written—'Mitridate, Re di Ponto' (1770) and 'Lucio Silla' (1775) for Milan, "La Finta Giardiniera' (1775) for Munich, and 'Il Re Pastore' (1775) for Salzburg. They adhere pretty closely to the conventional forms of the day, and, in spite of the beauty of many of the airs, can scarcely be said to contain much evidence of Mozart's incomparable genius. In 1778 the young composer visited Paris, where he stayed for several months. This period may be looked upon as the turning-point in his operatic career. In Paris he heard the operas of Gluck and Grétry, besides those of the Italian composers, such as Piccinni and Sacchini, whose best works were written for the French stage. He studied their scores carefully, and from them he learnt the principles of orchestration, which he was afterwards to turn to such account in 'Don Giovanni' and 'Die Zauberflöte,' The result of his studies was plainly visible in the first work which he produced after his return to Germany, 'Idomeneo.' This was written for the Court Theatre at Munich, and was performed for the first time on the 29th of January, 1781. The libretto, by the Abbé Giambattista Varesco, was modelled upon an earlier French work which had already been set to music by Campra. Idomeneo, King of Crete, on his way home from the siege of Troy, is overtaken by a terrific storm. In despair of his life, he vows that, should he reach the shore alive, he will sacrifice the first human being he meets to Neptune. This proves to be his son Idamante, who has been reigning in his stead during his absence. When he finds out who the victim is—for at first he does not recognise him—he tries to evade his vow by sending Idamante away to foreign lands. Electra the daughter of Agamemnon, driven from her country after the murder of her mother, has taken refuge in Crete, and Idomeneo bids his son return with her to Argos, and ascend the throne of the Atreidæ. Idamante loves Ilia, the daughter of Priam, who has been sent to Crete some time before as a prisoner from Troy, and is loved by her in return. Nevertheless he bows to his father's will, and is preparing to embark with Electra, when a storm arises, and a frightful sea monster issues from the waves and proceeds to devastate the land. The terror-stricken people demand that the victim shall be produced, and Idomeneo is compelled to confess that he has doomed his son to destruction. All are overcome with horror, but the priests begin to prepare for the sacrifice. Suddenly cries of joy are heard, and Idamante, who has slain the monster single-handed, is brought in by the priests and people. He is ready to die, and his father is preparing to strike the fatal blow, when Ilia rushes in and entreats to be allowed to die in his place. The lovers are still pleading anxiously with each other when a subterranean noise is heard, the statue of Neptune rocks, and a solemn voice pronounces the will of the gods in majestic accents. Idomeneo is to renounce the throne, and Idamante is to marry Ilia and reign in his stead. Every one except Electra is vastly relieved, and the opera ends with dances and rejoicings.
The music of 'Idomeneo' is cast for the most part in Italian form, though the influence of Gluck is obvious in many points, particularly in the scene of the oracle. Here we find Mozart in his maturity for the first time; he has become a man, and put away childish things. In two points 'Idomeneo' is superior to any opera that had previously been written—in the concerted music (the choruses as well as the trios and quartets), and in the instrumentation. The chorus is promoted from the part which it usually plays in Gluck, that of a passive spectator. It joins in the drama, and takes an active part in the development of the plot, and the music which it is called upon to sing is often finer and more truly dramatic than that allotted to the solo singers. But the chorus had already been used effectively by Gluck and other composers; it is in his solo concerted music that Mozart forges ahead of all possible rivals. The power which he shows of contrasting the conflicting emotions of his characters in elaborate concerted movements was something really new to the stage. The one quartet in Handel's 'Radamisto' and the one trio in his 'Alcina,' magnificent as they are, are too exceptional in their occurrence to be quoted as instances, while the attempts of Rameau and his followers to impose dramatic significance into their concerted music, though technically interesting, do but faintly foreshadow the glory of Mozart. The orchestration of 'Idomeneo,' too, is something of the nature of a revelation. At Munich, Mozart had at his disposal an excellent and well-trained band, and this may go far to explain the elaborate care which he bestowed upon the instrumental side of his opera. The colouring of the score is sublime in conception and brilliant in detail. Even now it well repays the closest and most intimate study. 'Idomeneo' is practically the foundation of all modern orchestration.
Mozart's next work was very different both in scope and execution. It has already been pointed out that the two first works which the composer, as a child, wrote for the stage, followed respectively the Italian and German models. Similarly, he signalised his arrival at the full maturity of his powers by producing an Italian and German masterpiece side by side. 'Die Entführung aus dem Serail' was written for the Court Theatre at Vienna, in response to a special command of the Emperor Joseph II. It was produced on July 13, 1782. The original libretto was the work of C.F. Bretzner, but Mozart introduced so many alterations and improvements into the fabric of the story that, as it stands, much of it is practically his own work.
The Pasha Selim has carried off a Christian damsel named Constanze, whom he keeps in close confinement in his seraglio, in the hope that she may consent to be his wife. Belmont, Constanze's lover, has traced her to the Pasha's country house with the assistance of Pedrillo, a former servant of his own, now the Pasha's slave and chief gardener. Belmont's attempts to enter the house are frustrated by Osmin, the surly major-domo. At last, however, through the good offices of Pedrillo, he contrives to gain admission in the character of an architect. Osmin has a special motive for disliking Pedrillo, who has forestalled him in the affections of Blondchen, Constanze's maid; nevertheless he is beguiled by the wily servant into a drinking bout, and quieted with a harmless narcotic. This gives the lovers an opportunity for an interview, in which the details of their flight are arranged. The next night they make their escape. Belmont gets off safely with Constanze, but Pedrillo and Blondchen are seen by Osmin before they are clear of the house. The hue and cry is raised, and both couples are caught and brought back. They are all condemned to death, but the soft-hearted Pasha is so much overcome by their fidelity and self-sacrifice that he pardons them and sends them away in happiness.
Much of 'Die Entführung' is so thoroughly and characteristically German, that at first sight it may be thought surprising that it should have succeeded so well in a city like Vienna, which was inclined to look upon the Singspiel as a barbarian product of Northern Germany. But there is a reason for this, and it is one which goes to the root of the whole question of comic opera. Mozart saw that Italian comic operas often succeeded in spite of miserable libretti, because the entire interest was concentrated upon the music, and all the rest was forgotten. The German Singspiel writers made the mistake of letting their music be, for the most part, purely incidental, and conducting all the dramatic part of their plots by dialogue. Mozart borrowed the underlying idea of the opera buffa, applied it to the form of the Singspiel, which he kept intact, and produced a work which succeeded in revolutionising the history of German opera. But, apart from the question of form, the music of 'Die Entführung' is in itself fine enough to be the foundation even of so imposing a structure as modern German music. The orchestral forces at Mozart's disposal were on a smaller scale than at Munich; but though less elaborate than that of 'Idomeneo,' the score of 'Die Entführung' is full of the tenderest and purest imagination. But the real importance of the work lies in the vivid power of characterisation, which Mozart here reveals for the first time in full maturity. It is by the extraordinary development of this quality that he transcends all other writers for the stage before or since. It is no exaggeration to say that Mozart's music reveals the inmost soul of the characters of his opera as plainly as if they were discussed upon a printed page. In his later works the opportunities given him of proving this magical power were more frequent and better. The libretto of 'Die Entführung' is a poor affair at best, but, considering the materials with which he had to work, Mozart never accomplished truer or more delicate work than in the music of Belmont and Constanze, of Pedrillo, and greatest of all, of Osmin.
