The Composition
Nabucco (full title: Nabucodonosor) is an opera in four acts with music by Giuseppe Verdi and libretto by Temistocle Solera, premiered at La Scala, Milan, on 9 March 1842. Verdi was twenty-eight at its premiere, and the work was his third opera and first great success; it established him virtually overnight as the most important Italian operatic composer of his generation. The opera runs approximately two hours and fifteen minutes and is scored for soprano (Abigaille), mezzo-soprano (Fenena), two tenors (Ismaele, Abdallo), baritone (Nabucco/Nebuchadnezzar), bass (Zaccaria), chorus, and full Romantic orchestra.
Verdi reportedly accepted the commission reluctantly, being in a state of personal grief following the deaths of his wife and two infant children in 1839-40. According to Verdi's own account, the libretto fell open at the chorus 'Va, pensiero, sull'ali dorate' ('Fly, thought, on wings of gold'), and its text - the Hebrew exiles lamenting their captivity by the rivers of Babylon - moved him so deeply that he set it to music almost involuntarily. Whether or not the account is literally true, it captures the opera's extraordinary relationship to its composer's own grief and to the collective grief of the Italian nation under Austrian occupation.
Biblical Text
The opera draws on 2 Kings 25 (the Babylonian conquest and exile of Judah under Nebuchadnezzar), Daniel 1-5 (the Babylonian court narratives, including Nebuchadnezzar's madness and restoration), and Psalm 137 (the lament of the exiles). Solera's libretto takes considerable historical and dramatic liberties: Abigaille, the opera's principal soprano and main dramatic force, is a fictional character; the love plot involving Fenena and Ismaele is invented; and the historical Nebuchadnezzar's story is compressed and dramatized. But the theological core - the humiliation of a proud king, the survival of the faithful people, and the ultimate recognition of the God of Israel as the only true God - follows the biblical narrative faithfully.
The climactic 'Va, pensiero' directly paraphrases Psalm 137:1-3: 'By the rivers of Babylon we sat and wept when we remembered Zion. There on the poplars we hung our harps, for there our captors asked us for songs... saying, "Sing us one of the songs of Zion!"' Solera's text transforms the psalmist's refusal to sing into an act of collective memory - the exiles do sing, to each other, about the land they have lost - which carries a political charge that the original psalm's refusal does not.
The Composer
Verdi was himself, in 1842, living in a kind of personal exile - grief-stricken, professionally uncertain, feeling cut off from the creative life he had known before his family's deaths. The identification of the young composer with the exiled Hebrews of Psalm 137 was not merely political but personal and existential. Verdi later said that in Nabucco he had found his true artistic self, the voice that would carry him through forty years of subsequent composition. The opera marks the beginning of the 'galley years' - the period of intense productivity (1842-49) in which Verdi wrote sixteen operas in rapid succession.
Musical Analysis
Nabucco is not a subtle opera. Its music is direct, forceful, and dramatically effective in broad strokes rather than careful characterization. The opening scene in the Temple of Jerusalem, with the Hebrew chorus 'Gli arredi festivi' lamenting the Babylonian approach, establishes the opera's sound world: strong unison melodies, powerful bass-line support, dramatic harmonic shifts. The title role (baritone) is one of the most demanding Verdi ever wrote, requiring both heroic strength and, in the mad scene, a kind of fragmented lyric tenderness as Nebuchadnezzar's megalomania crumbles.
'Va, pensiero' is structurally unlike any other chorus in Italian opera. It is entirely homophonic - all voices moving together in simple chords - with a long-breathed melody in the high tenors that the other voices support. There is no fugal imitation, no dramatic contrast, no theatrical surprise: just a community singing together about a lost homeland. Its effect, both in the opera and in concert performance, is of collective mourning so fundamental that it bypasses individual differences entirely. Verdi reportedly said that this unison of voices representing a people's shared grief was the musical image of everything he believed about community and belonging.
Theological Content
The theological arc of Nabucco follows the biblical narrative closely: the proud king who makes himself God (echoing Daniel 4 and Isaiah 14) is humiliated by the true God, restored to sanity through suffering, and ultimately converts - proclaiming Jehovah as the only God (Daniel 4:34-37). This arc of pride, humiliation, and restoration is one of the foundational patterns of biblical theology, appearing in the stories of Pharaoh, Nebuchadnezzar, and Herod and in the theological reflections of Isaiah, Daniel, and the Psalms. The opera's Italian nationalist audience in 1842 read this pattern differently - as the humiliation of Austrian power and the eventual restoration of Italian freedom - but the biblical pattern undergirds both readings.
Performance History
Nabucco was immediately and massively successful in Milan and was performed in the major Italian opera houses within a year. Its progress through European opera houses was equally rapid. The chorus 'Va, pensiero' became so identified with Italian national aspiration that there were calls - partially successful - to make it Italy's national anthem. Following Italian unification in 1861, the chorus remained a symbol of collective grief and hope. At Verdi's funeral procession in 1901, the gathered crowd spontaneously began singing 'Va, pensiero.'
Notable Recordings
The opera has been recorded many times. Riccardo Muti's 1977 account (with Matteo Manuguerra as Nabucco and Renata Scotto as Abigaille, EMI) is widely regarded as the finest. More recent recordings include those of Daniel Oren (Decca, 2000) and Nello Santi. The chorus 'Va, pensiero' has been recorded as a concert piece by virtually every major choral ensemble.
Legacy
Nabucco established Verdi's reputation and launched the most productive career in the history of Italian opera. More broadly, 'Va, pensiero' became the supreme example of how a biblical text - Psalm 137's lament of exile - can be appropriated as the expression of a entirely different historical community's grief and hope, demonstrating the psalm's extraordinary capacity for recontextualization across twenty-five centuries. The opera also is a reminder that the biblical narratives of exile, humiliation, and restoration speak not only to their original historical recipients but to any community that finds itself dispossessed, governed by an alien power, and longing for home.
