The final emancipation of the serious basso (the comic basso was already eligible for leading parts) dates from the production of “Mosè,” in 1818. The liberation was gradual; for, both in “Tancredi” and in “Otello,” exceptional prominence had been given to what was formerly called and considered the ultima parte. In “La Gazza Ladra,” too, which, however, was not an opera seria, but an opera of mezzo carattere, Galli, who was afterwards to appear as Maometto and Assur, had played the bass or baritone part of Fernando.
It may be said that Rossini, having two basses at hand, composed the parts of Mosè and Faraone for them; as, in 1816, having two first tenors to write for, he assigned to them the characters of Otello and Iago. But it is more reasonable to infer that he had now determined to grant the bass his natural dramatic rights, as the representative of imposing and gloomy, as well as of jovial parts.
By this innovation, moreover, Rossini gave variety to his casts, and increased his resources for concerted music. Probably he would have introduced it before could he have found the singers he wanted among the companies he had engaged to write for. But it was not the custom at the time of Rossini’s youth for composers to give important parts to bass singers; and it was only the demand for leading basses created by Rossini which afterwards caused the supply. Moving constantly about from one theatre, one city, to another, and producing three operas a year, he was obliged to write his music according to his singers’ voices.
Meyerbeer, when he had begun to compose for the French opera, would wait patiently, month after month, and year after year, until he could find just the voice he wanted; but he did not, like Rossini, compose thirty-four operas before he was thirty-two years of age.
The choral portion of “Mosè” is all important. The chorus of the plague of darkness, in the first act, was found one of the most impressive pieces when the work was first produced; and this was quite surpassed at subsequent representations by the admirable preghiera of the passage of the Red Sea, where the same melody, with just one significant shade of difference, is heard, first in the minor, as a plaintive supplication, afterwards in the major, as a joyous thanksgiving. Nothing is more simple, nothing can be more perfect. The music thoroughly beautiful, the effect thoroughly dramatic.
“Among other things that can be said in praise of your hero, do not forget that he is an assassin,” remarked Dr. Cottougna of Naples to the Abbé Carpani, at the time of the general enthusiasm caused by “Mosè.” “I can cite to you,” he continued, “more than forty attacks of nervous fever, or violent convulsions on the part of young women fond to excess of music, which have no other origin than the prayer of the Hebrews in the third act, with its superb change of key.”
In England “Mosè” is scarcely known. The work being unpresentable on our stage in its original form, was brought out, a few years after its production as an oratorio, and afterwards, with a complete transformation in the libretto, as an opera under the title of “Pietra Eremita.” The operatic version was given at the King’s Theatre with so much success that it attracted large audiences during an entire season. No nervous fevers, no convulsions, were placed to its account; but the subscribers were in ecstacies, and one of the most distinguished supporters of the theatre assured Mr. Ebers, the manager, that he deserved well of his country, and offered as a proof of gratitude to propose him at White’s.
It has been recorded that when “Moïse,” the French version of “Mosè in Egitto,” as remodelled by Rossini, was brought out at the French Opera, forty-five thousand francs were sunk in the Red Sea, and to no effect. In London the Red Sea became merely a river, which, however, failed quite as signally as the larger body of water, and had to be drained off before the second performance took place.
An Italian version of the French version of the original Italian version of “Mosè” was produced at the Royal Italian Opera some twenty years ago under the title of “Zora.” It had no permanent success, and was not even played a second season. The piece was found too long, too heavy—it was living music united to a dramatic corpse.
The beautiful prayer, however, survives, and will doubtless long continue to survive the rest of the work. Played on a single instrument, as by Sivori on the violin, at the service performed in memory of Rossini at Florence, or sung by thousands of vocalists to the accompaniment of some hundreds of musicians, as at various musical gatherings in London and Paris, the melody is always touching, the mass of harmony always impressive.
