Debut

In 1852, after much insistence from Faldi and castrato Domenico Mustafà, among others, he agreed to sign a contract for his debut at Rome's Teatro Metastasio, as Belcore in L'elisir d'amore. For the next year, he did not sing in public at all but rather studied assiduously with Faldi to build his repertoire. After an initial contract at Spoleto for Il trovatore and Maria di Rohan, he began to pick up consistent work in the Italian regional operatic circuit: Lanciano for Trovatore, Rigoletto, and Maria di Rohan; Orvieto for I masnadieri; Lucrezia Borgia in several cities; I puritani at Perugia.

In the spring of 1857, he was signed by the impresario Jacovacci for Lucia di Lammermoor and Gemma di Vergy at Rome's Teatro Argentina. In September and October of that year, he performed I due Foscari and Luisa Strozzi at Teatro Rossini in Turin. It was then that he met the soprano Maria Ballerini. They married the next year but never had any children together.^[2]: 26

Following that, Cotogni was engaged for Foscari and La traviata at Asti and then Cuneo, the Teatro Rossini again, Zara, in Genova, and at Turin for the opening of the new Teatro Alfieri. There he was asked by the impresario Scalaberni to take the place of the famous baritone Felice Varesi in an operatic company being formed for the theater in Nice. During his time in Nice, Cotogni studied the role of Don Giovanni with his predecessor, Italian baritone Antonio Tamburini, who had left the stage in 1855.

Breakthrough

The turning point in Cotogni's career came in late 1858. As soon as he arrived in Nice for rehearsals in October, he began to feel an air of contempt for his presence from everyone from the theater to public restaurants and cafés. Those who knew and loved Varesi felt that Cotogni, an virtually unknown singer, had been hastily and unfairly chosen to replace him. The first role he was engaged to sing was of Antonio in Gaetano Donizetti's Linda di Chamounix in Nice,^[4] where the audience greeted him with noises and whistling before he had even opened his mouth. This same audience fell silent during Antonio's opening aria "Ambo nati in queste valle" and gave him a unanimous, colossal applause after the cadenza, demanding a bis.^{[2]: 27–28} That performance assured his place on the scene and revealed him to be an absolute master of his art—technically, stylistically, and dramatically. Consequently, this became one of Cotogni's signature roles, one by which he made great impressions on all the great theaters of Europe and even the most sullen critics. In Nice, he followed Linda with Gemma di Vergy, Rigoletto, La favorita, Traviata, Trovatore, Don Pasquale, Roberto Devereux, Don Sebastiano, and Il barbiere di Siviglia.

He sang with enormous success over the next year—I lombardi, Rossini's Otello, and Nabucco in Viterbo; again at Nice for Lucia di Lammermoor, Ernani, Trovatore, and Maria di Rohan; and at Barcelona's Teatro Principal for Saffo, Traviata, Attila, Gemma, Barbiere, and Trovatore. By October 1860, Cotogni had sung in 21 theaters, and it was at this point that he reached La Scala, Milan, debuting there in the role of Giovanni Bandino in Bottesini's L'assedio di Firenze. Cotogni had been nervous about this debuting, doubting his ability to do it justice and doubting the power of his voice to be heard in the theater. The reviews of the debut were encouraging, but one or two critics mentioned a certain tremulousness and constriction in his high notes. But Cotogni regained his composure after the premiere, and won over the Milan public with his other roles that season—William Tell, Peri's Vittor Pisani, Rodolfo in La sonnambula, and Ezio in Attila.

During the ensuing decades, he also appeared at the leading opera houses in Madrid, Lisbon, Paris, London, Moscow, and Saint Petersburg. He became enormously popular with London audiences, performing at the Royal Opera House, Covent Garden, from 1867 to 1889. He sang at Saint Petersburg in 26 successive seasons.^[5]

It was in 1894 at Saint Petersburg that he gave his last operatic stage performance, in Donizetti's Don Pasquale. While Cotogni had spent his career singing the opera's baritone role of Dr. Malatesta, the younger baritone Mattia Battistini was now taking over many of the Cotogni's old roles. Nevertheless, Battistini requested Cotogni to honor the company by joining them in one final performance, only this time asking that he sing the lead comic bass role of Don Pasquale, which Cotogni obliged.^{[2]: 69–70}

Students & Protégés

Ricci reports that when in 1912 he attended performances at Moscow's Imperial theater and Zimina Opera, as well as at the Imperial Theater in St. Petersburg, half of the artists on stage had been Cotogni's students. For nearly 20 years, Cotogni dedicated himself to teaching singing. Many artists already in the fullness of their careers also came to study with him at the Liceo and/or learn from him privately.

Range

According to his biographer, Cotogni's professional/usable vocal range was from A₁ to B₄, though a handful of his roles and even his interpolations and cadenzas require a half-step lower—A♭₁. According to Ricci, his other noted interpolations include a high G♯ in Posa's romanza "Carlo, ch'è sol il nostro amore" in Don Carlo; high A♭'s in "O de verd'anni miei" and "O sommo Carlo" from Ernani and the end of "Suoni la tromba" in I puritani; and a quick high A♮in a roulade on the word "piacere" in "Largo al factotum" from Il barbiere di Siviglia.^[10] He did, however, chide Titta Ruffo for interpolating an unwritten high B♭ in Hamlet.^{[note 2]} It is therefore unlikely that Cotogni ever sang a note above the high A♮ in public performance. Of physiological interest is the fact that Cotogni suffered from a lateral lisp that affected his speech but that disappeared when he sang.^{[note 3]}

The famed Italian conductor Toscanini remarked that Cotogni's voice was totally even and that "one didn't hear the transition between the registers... Hearing it, it seemed that everything was natural, while, instead, the poor Cotogni had practiced for years and years to acquire that perfection."^[13]

Critical reception

Journalistic reviews of his performances were often superlative.

A full voice that is mellow, flexible, and well-schooled; persona; expression; and mastery of the scene all combine to make Cotogni the model artist, a perfect singer. The public hangs on every word from his lips. The pathetic scene of the recognition of the daughter, Cotogni masterfully portrayed the truth, singing and reciting his part with heartbreaking accent. He painted ever so gently his romance "Ambo nati," and the first act duet with the thunderous Nannetti[...] was a real delirium, [stirring] unheard of fanaticism. Even I, an old theatergoer, have never heard the duet performed with such color, with so much strength and homogeneity.

Cotogni, who can well be called the prince of baritones today, has definitively captivated the audience. This singer, of a voice both powerful and suave, really is something extraordinary. He sings like few can sing, and although his part fraught with difficulties, he breaks down everything and overcomes them with ease, with astounding ownership; in him one find not effort nor the slightest fatigue: even if sometimes he has been singing with full vibration and power, his voice can still come out quiet and safe. His ways are often exceptional, and not content with the difficulties inherent to the score, he will add new ones—always tasteful, and it seems he delights in defying them. The voice of this singer leaves an everlasting impression on you.

— Pietro Faustini, Gazzetta Musicale di Milano

The voice of the Cotogni is full, smooth, equal, of a most sympathetic timbre, and it moves the audience especially when he sings a fior di labbra. This most perfect artist makes every one of his parts into a creation. With great difficulty could there ever arise another singer who could emulate him; surpass him, never.

Gramophone recording

Cotogni ranks with his contemporaries Francesco Graziani (baritone), Jean-Baptiste Faure and Sir Charles Santley as the foremost baritone of his star-studded generation. He "had a very brief and scarcely revealing relationship with the gramophone; at the age of 77... with the tenor Francesco Marconi, he recorded [the] duet 'I mulattieri'" (by Francesco Masini), writes Michael Scott.^[14] "Not surprisingly Marconi gets the better of it. Still, however difficult it is to make out Cotogni's contribution, it is all we have left of a singer who for over 40 years dominated the stages in London, Madrid and Lisbon, St. Petersburg and Moscow and throughout Italy."

Two other recordings, at times believed to be of Cotogni, are in fact the voice of tenore robusto Francesco Tamagno's brother, Giovanni. Comparisons of these two recordings—"O casto fior" and Stanislao Gastaldon's "Ti vorrei rapire" (formerly misidentified as "Perché?")^[15]—with the Tamagno brothers' recording of the Otello duet "Si pel ciel" reveals the baritone voice to be identical in timbre and production, with its thin and nasal qualities, especially in the passagio. These stand in contradistinction to the voice confirmed to be Cotogni's (the Mulattieri duet),^[16] which is noticeably more even, round, and sonorous throughout—even to the two high G naturals that end the refrain. In the Roman school, and in Cotogni's own teaching, any nasality was seen as a defect to be expressly avoided.
