Verdi's father, Carlo Giuseppe Verdi, an innkeeper and owner of a small farm, gave his son the best education that could be mustered in a tiny village, near a small town of about 4,000 inhabitants, in the then-impoverished Po Valley. The child must have shown unusual talent, for he was given lessons from his fourth year, a spinet was bought for him, and by age 9 he was standing in for his teacher as organist in the village church. He attended the village school and at 10 the ginnasio (secondary school) in Busseto.

A little later he composed music (now lost) for the town church and the largely amateur orchestra. One of Busseto's leading citizens, Antonio Barezzi, a merchant and fanatical music enthusiast, became a second father to the young prodigy, taking him into his home, sending him to study in Milan, and in 1836 giving him his daughter Margherita in marriage. Refused by the Milan Conservatory—he was past the admission age and played the piano poorly—Verdi studied privately with Vincenzo Lavigna, an older composer and an associate of La Scala opera house (Teatro alla Scala). Milan was the intellectual and operatic centre of Italy, and in the years 1832–35 Verdi seems to have learned much about literature and politics there as well as counterpoint and the elements of opera. Later, after his great success with Nabucco, he attended literary salons in the city and made lasting friendships with some cultivated aristocrats.

Barezzi's plan was for Verdi to return to Busseto as music director, but when this post fell open in 1833 a furious political storm developed leading to long delays. Soured by this, Verdi nonetheless took a compromise position and stayed from March 1836 to October 1838, teaching and composing a good deal, though all he published was a set of songs in 1838.

Needless to say, he had his eye on greater things. The music that he had written during these years must have impressed the right people, for after some difficulty he succeeded in getting an opera, Oberto, conte di San Bonifacio, produced at La Scala in March 1839. Ordinary as the piece may seem today, it succeeded well enough to travel to Genoa and Turin and to gain him a commission for three more operas at Italy's leading theatre. His rising career was deflected by tragedy: in 1840 his young wife died, following the deaths of two infant children. In addition to this personal grief, Verdi saw his next opera, Un giorno di regno (King for a Day), a comedy, hissed off the stage. This compounded trauma led to a severe depression and either caused or fixed the dour, fatalistic, sometimes harsh aspects of Verdi's character.

Verdi overcame his despair by composing Nabucodonoser (composed 1841, first performed 1842; known as Nabucco), based on the biblical Nebuchadnezzar ( Nebuchadrezzar II), though the well-known story he told later about snapping out of his lethargy only when the libretto fell open at the chorus “Va, pensiero”—by that time one of his most beloved works—is no longer credited. (The older Verdi embroidered on various aspects of his early life, exaggerating the lowliness of his origins, for example.) Nabucco succeeded as sensationally as Un giorno had failed abjectly, and Verdi at age 28 became the new hero of Italian music. The work sped across Italy and the whole world of opera; within a decade it had reached as far as St. Petersburg and Buenos Aires, Argentina. While its musical style is primitive by the composer's later standards, Nabucco's raw energy has kept it alive a century and a half later.

There followed a period (1843–49) during which Verdi drove himself like a galley slave, as he himself put it, and to the detriment of his health, to produce nearly two operas a year. His aim was to make enough money for early retirement as a gentleman farmer at Sant'Agata, close to Roncole, where his forebears had settled. He purchased land there as early as 1844. To “produce” an opera meant, at that time, to negotiate with an impresario, secure and edit (often heavily) a libretto, find or approve the singers, compose the music, supervise rehearsals, conduct the first three performances, deal with publishers, and more—all this while shuttling from one end of Italy to the other in the days before railroads.

Only with Macbeth (1847), however, was Verdi inspired to fashion an opera that is as gripping as it is original and, in many ways, independent of tradition. Just as the biblical theme had contributed to the grandeur of Nabucco, so the tragic theme of Shakespeare's drama called forth the best in him. Verdi knew the value of this work and revised it in 1865, excising some of its crudities; but its greatest number, the harrowing sleepwalking scene of Lady Macbeth, could be left just as it was written in 1847.

By that time he was receiving lucrative commissions from abroad—from London (I masnadieri) and Paris (Jérusalem, a thorough revision of I Lombardi, 1847). La battaglia di Legnano (1849; The Battle of Legnano), a tale of love and jealousy set against the Lombard League's victory over Frederick Barbarossa (Frederick (I)) in 1176 CE, was Verdi's emphatic response to the Italian unification movement, or Risorgimento, which spilled over into open warfare in 1848, the year of revolutions. Greeted ecstatically at the time, this opera later faded.

It is often said that in the earlier operas, too, choruses and other numbers calling for liberation or revolt were taken metaphorically as revolutionary rallying cries, and evidently this did happen on isolated occasions. However, it was only after unification in 1861, when the conte di Cavour (Cavour, Camillo Benso, conte di (count of)), seeking to involve as many important Italians as possible, persuaded the composer to stand for the Chamber of Deputies—which he attended faithfully but soon resigned from—that Verdi came to be widely celebrated as a national hero. “Va, pensiero,” the song of the enslaved Hebrews in Nabucco, assumed the status of an unofficial national anthem. That the vision of Verdi as “singer of the Risorgimento” owes less to historical fact than to patriotic nostalgia should not be thought to diminish its significance; adapted to words about the downtrodden masses, “Va, pensiero” could still be heard at Italian communist rallies in the 1990s.

The prima donna who created Abigaille in Nabucco, Giuseppina Strepponi, who also had helped Verdi as early as 1839 with Oberto, ultimately became his second wife. Her love, support, and practical assistance on behalf of Verdi, over half a century, was boundless, though he was not an easy husband.

Born in 1815, Strepponi had a quite successful, if short, career. Living for a time with her agent, one Camillo Cirelli, in effect as common-law wife, she had borne three children, the oldest of whom (her only son, Camillino) was reared by her former maid. (The two other children were daughters and were given up for adoption.) When her voice began to deteriorate she set up as a teacher in Paris, where Verdi met her again in 1847 while there to produce Jérusalem. They fell in love and were soon living together, though they did not marry until 1859. Strepponi, a devout Catholic, seems to have felt herself unworthy to be Verdi's wife, a feeling that one suspects Verdi may have shared on some level. It also seems possible that marriage was put off until her son came of age in 1859.

The new richness and depth of Verdi's musico-dramatic characterization in these years, especially though not exclusively of women, may have developed out of his relationship with Strepponi. She is often evoked in connection with the sympathetic and radiant portrayal of Violetta in La traviata (The Fallen Woman—a rough analogy, to be sure, for Violetta the courtesan had fallen a great deal farther than Strepponi the singer). Yet Verdi showed scant sympathy for the real-life woman when he determined to move back with her to Busseto in 1849 and then to Sant'Agata, where small-town outrage at their liaison reached a peak. For some time he refused to allow her to accompany him on his many travels, which left her alone in a very hostile environment. He himself responded furiously to local censure and refused to have anything to do with Busseto and its musical activities, having first scrupulously repaid with interest the contribution made by the commune to his musical education.

By this time he had honed his skills as a competitor in the rapacious marketplace that was 19th-century Italian opera—or, as he always saw it, the grim site of major battles, endless skirmishes, and equivocal victories. He drove hard bargains, complained bitterly at every reverse, stonewalled, and sued. He tried to insist that his operas be performed exactly as written, without cuts, transpositions, or substitutions.

He met his match with the censors, especially after 1848. The plot of Le roi s'amuse, the play by Hugo that inspired Rigoletto, features a curse that was deemed blasphemous and the attempted murder of a king that was politically taboo; only after the king was demoted to a duke and various other modifications were made could the text be approved. Traviata experienced problems of another kind. With La Dame aux camélias (“The Lady of the Camellias”), fils (Dumas, Alexandre, fils) had just caused a considerable scandal in Paris, and Verdi's operatic version, though at first performed in 17th-century costumes, too obviously broke from operatic convention in setting a present-day subject, and a risqué one at that. For this reason and also because a stout prima donna had been cast as the consumptive heroine, the first performance was a rare Verdi fiasco. “Is it my fault or the singers'? Time will show,” was Verdi's characteristically laconic comment. After minor revisions and a new production, the opera carried all before it.

Verdi had become an international celebrity, and the change in his status was reflected in his art. From 1855 to 1870 he devoted himself to providing works for the Opéra at Paris and other theatres conforming to the Parisian operatic standard, which demanded spectacular dramas on subjects of high seriousness in five acts with a ballet. He was pointedly challenging Giacomo Meyerbeer (Meyerbeer, Giacomo), the one European composer more renowned and wealthier than he was, on Meyerbeer's own ground. While these operas show advances in many areas and include superb scenes, none of them is as satisfactory as a whole as any of the three great operas of the early 1850s.

His first essay in the new manner, Les Vêpres siciliennes (1855; The Sicilian Vespers), is a rather cold piece that has had only lukewarm success from its premiere on. The fault lay partly in the libretto—by Meyerbeer's own librettist, the poet Eugène Scribe (Scribe, Eugène); Scribe merely refashioned an old piece he had written for Gaetano Donizetti (Donizetti, Gaetano).

Two pieces for Italian theatres, Simon Boccanegra (1857) and Un ballo in maschera (1859; A Masked Ball), affected to a lesser extent by the impact of the grand operatic style, show the enrichment of Verdi's power as an interpreter of human character and as a master of orchestral colour. Boccanegra, despite a gloomy and excessively complex plot, includes powerful scenes and creates a special windswept atmosphere appropriate to its Genoese pirate protagonist. (Verdi often spoke of the unique tinta 【“colour”】 of each of his operas.) Much more successful with the public was Ballo, a romantic version of the assassination of Gustav III of Sweden—even though again the censorship barred the murder of a king and so made nonsense of the story, its setting transported from 18th-century Stockholm to Puritan Boston, a hundred years earlier. These years also saw Aroldo (1857), an unsuccessful revision of Stiffelio (1850).

In 1862 Verdi represented Italian musicians at the London Exhibition, for which he composed a cantata to words by the up-and-coming poet and composer Arrigo Boito (Boito, Arrigo). In opera the big money came from foreign commissions, and in the same year his next work, La forza del destino (The Force of Destiny), was produced at St. Petersburg. Always on the lookout for novel dramatic material, Verdi had wanted to tackle the epic narrative extending over many years and many locations, with scenes of high life and low. This he managed in Forza, which also includes the most extended religious scene in a Verdi opera and his first substantial comic role, that of the irascible Friar Melitone. Verdi finally surpassed Meyerbeer at the Paris Opéra (at least according to opinion at the turn of the 21st century—though not at the time) with Don Carlos (1867), a setting of another play by Schiller that is for once worthy of the original—and in which religion is portrayed much more harshly, and much more in accordance with Verdi's lifelong strong anticlerical sentiments, than in Forza. Despite its problematic ending, Don Carlos is regarded by some as Verdi's masterpiece, or at least his masterpiece prior to the Shakespeare operas of his last years.

Verdi felt that both operas with foreign commissions required revision for Italian theatres; this he accomplished for Forza in 1869 and Don Carlo (as it is now usually called) in 1884 and 1887. He needed none with the piece in which at last he fashioned a libretto exactly to his needs, Aida. Verdi wrote a detailed scenario—much simpler than those of the previous two operas—employing Antonio Ghislanzoni, a competent poet, to turn it into verse, the metres of which were often dictated by the composer. Commissioned by the khedive of Egypt to celebrate the opening of Cairo's new Opera House in 1869 (Verdi had earlier declined a commission for an inaugural hymn celebrating the opening of the Suez Canal), Aida finally premiered there in 1871 and went on to receive worldwide acclaim. Verdi had achieved the grandeur and the gravitas of the Parisian style without its notorious excess padding and without any weak spots, and onto it he had grafted an emotional intensity that only he could furnish.

When Gioachino Rossini (Rossini, Gioachino), the most revered figure in modern Italian music, died in 1868, Verdi proposed that a requiem mass in his honour be composed by himself and a dozen of his contemporaries. The project collapsed and Angelo Mariani, who was to have conducted the performance, seemed to Verdi less than wholehearted in his support. Verdi, who could not bear being thwarted, visited his wrath on the unfortunate Mariani, who was the most distinguished Italian conductor of the day and, until then, had been one of his closest friends. The quarrel shows both Verdi and Giuseppina at their worst. Verdi could never forgive an injury, real or imagined, as attested to by his lifelong hatred of La Scala and its audience, which had rejected Un giorno di regno, and his contempt for the town of Busseto. The breach with Mariani widened when the conductor refused to go to Cairo to direct the first performance of Aida. He pleaded illness and was indeed suffering terribly from cancer, of which he died in 1873. Things reached a very ugly pitch when a scurrilous newspaper story accused Verdi of stealing Mariani's fiancée, the soprano Teresa Stolz.

Although little is known for certain, Giuseppina's private papers reveal her great distress. She worked valiantly to preserve the marriage, persevering in the most cordial relations possible with Stolz, who finally made some kind of break when she left Italy in 1876. Apparently Giuseppina had put her foot down. But two years later Stolz resumed visits to Sant'Agata, and it was clear the relationship had not blown over. Twenty years later, letters from Verdi that somehow escaped destruction speak of his love for Stolz. She was present at the composer's deathbed.

In 1873, while waiting in a Naples hotel for a production of Aida, Verdi wrote a string quartet, the only instrumental composition of his maturity. In the same year, he was moved by the death of the Italian patriot and poet Alessandro Manzoni (Manzoni, Alessandro) to compose a requiem mass in his honour. He was able to incorporate into it the final movement (“Libera me”) that he had written for the abortive Rossini mass. One of the masterpieces in the oratorio tradition, often heard in concert series into the 21st century, the Manzoni Requiem is an impressive testimony to what Verdi could do outside of the field of opera.

After 1873 the maestro considered himself retired, at long last, from that world of opera to which he had been bound for so many years in a love-hate relationship. He settled in at Sant'Agata, where the same iron hand and obsessive attention to detail that he had applied to operatic rehearsals came to control all aspects of his farming enterprise. A 20-year program of enlargement and improvement of his estates made him a major landholder and a very wealthy man. He funded major charities, of which the best known is the Casa di Riposo per Musicisti, a home for aged musicians that is still in operation in Milan.

His unintended and unimagined return to the stage, many years after Aida, was entirely due to the initiative of his publisher, Giulio Ricordi. Reluctant to allow his most profitable composer to rest on his laurels, Ricordi contrived a reconciliation with Arrigo Boito, who had offended Verdi by some youthful criticism. A proposal that Boito should write a libretto based on Shakespeare's (Shakespeare, William) Othello attracted the old composer, and, as a sort of test, the now-prominent man of letters and composer of the opera Mefistofele agreed to revise the unsatisfactory libretto of Simon Boccanegra. The latter opera is still performed because of Boito's revision of 1881. The Othello project then took shape, very slowly, on and off, until the opera finally opened at La Scala in 1887. In his 74th year, Verdi, stimulated by a libretto far superior to anything he had previously set, had produced his tragic masterpiece. In Otello the drama is absorbed into a continuous and flexible musical score vastly advanced in style over that of Aida, reflecting every aspect of the characters and every nuance of the action.

After a rapturous tour with Otello throughout Europe, Verdi once more retreated to Sant'Agata, declaring that he had composed his last opera. Yet Ricordi and Boito, who had grown very close to the old man, managed to intervene one more time. With infinite skill, Boito converted Shakespeare's The Merry Wives of Windsor, strengthened with passages adapted from the Henry IV plays, into the perfect comic libretto, Falstaff, which Verdi set to miraculously fresh and mercurial music (and this time with fewer delays). This, his last dramatic work, produced at La Scala in 1893, avenged the cruel failure of Verdi's only other comedy in the same theatre half a century earlier.

Even after Falstaff Verdi still interested himself in composition. His list of works ends with sacred music for chorus: a Stabat Mater and a Te Deum published, along with the somewhat earlier and slighter Ave Maria and Laudi alla Vergine Maria, under the title Quattro pezzi sacri (Four Sacred Pieces) in 1898. After a long decline Giuseppina had died in 1897, and Verdi himself gradually grew weaker and died four years later.

Born in the same year, Verdi and Richard Wagner created parallel, mutually exclusive types of opera that figure equally among the greatest achievements of 19th-century culture. Their works remain at the heart of opera repertory at the beginning of the 21st century.

Verdi appeared on the operatic scene just as the Italian bel canto tradition of Rossini, Vincenzo Bellini, and Donizetti, in the quarter-century from about 1815 to 1845, entered its waning phase. He transformed it and dominated Italian opera alone for another 30 years. It was a period of constant experimentation, constant refinement of musical and dramatic means—a process that seems to have continued underground to germinate the two transcendent Shakespeare operas written 20 years after his supposed retirement.

At first it was mainly his vigour and dramatic intelligence that distinguished his operas, works that audiences could feel were continuing safely in his predecessors' footsteps. But step by step Verdi modified the rigid conventions of bel canto opera, which showed off singers at the expense of dramatic values. Verdi's genius was to dismantle the system while still giving the singers (and their audiences) melody and brilliance in ample measure. All of this was in the service of drama, as Verdi always stressed, and drama, as he saw it, emerged from the interaction of people in striking, usually dire situations—people who were characterized unforgettably by Verdi's music. No opera composer has ever assembled a more varied and vivid portrait gallery: Rigoletto, evil jester and loving father; self-sacrificing Violetta of La traviata and self-destructive Amneris of Aida; implacable Fiesco in Simon Boccanegra; the page Oscar in Ballo; the passionate Leonora of Trovatore and the tormented Leonora of Forza; the truly Shakespearean Lady Macbeth; and Verdi's own Desdemona.

His operas move rapidly, with unerring dramatic rhythm. He developed a whole new musical vocabulary, which broadened the role of the orchestra without compromising the primacy of the voice. He introduced a range of subject matter never before touched in opera; the later Verdi could be subtle, gentle, and atmospheric as well as powerful. Generations of listeners the world over, in and out of the opera house, have loved Verdi's melodies. The best of them serve the drama, capturing his characters' emotions with a warmth and directness achieved by few other composers.
