This piece, as the title might suggest, brings together Verdi’s greatest operatic triumphs. Amongst his best hits are Nabucco from 1842, which signified a turn-around after the flop of a previous opera, as well as Rigoletto, which in 1851 propelled him to international fame. Verdi’s Triumphs features: Triumphmarch and Su! Del nilo al sacro lido from Aida, the Prisoners’ Freedom Choir from Nabucco and La donna è mobile from Rigoletto.

Zoals de titel al doet vermoeden, brengt dit werk de grootste triomfen van Verdi samen. Zijn bekendste opera’s zijn ongetwijfeld Nabucco uit 1842, maar ook Rigoletto uit 1851. Deze opera’s bezorgden hem eeuwige roem. In Verdi’s Triumphs vinden we de Triumphmarch en Su! Del nilo al sacro lido uit Aida, het Prisoners’ Freedom Choir uit Nabucco en La donna è mobile uit Rigoletto terug.

Zu Verdis größten Triumphen zählen sicherlich die Opern Nabucco von 1842, die eine Wende nach einigen Misserfolgen markierte, Rigoletto, die ihm 1851 zum internationalen Durchbruch verhalf und Aida, die er zur Eröffnung des Suezkanals schrieb. Auch aus heutiger Sicht sind gerade diese Werke besonders bekannt und beliebt. Daher wählte Wil van der Beek für sein Arrangement die folgenden Titel: Triumphmarsch und Su! Del nilo al sacro lido aus Aida, den Chor der Gefangenen aus Nabucco sowie La donna è mobile aus Rigoletto.

Cette oeuvre comme le titre l'indique, rassemble les plus grands trimphes d'opéras de Verdi. On retrouve bien entendu Nabucco, Aida ainsi que Rigoletto. Verdi's Triumphs contient les titres suivants : Marche Trimphale ! Del nilo al sacro lido extrait d'Aida, Prisoners' Freedom Choir extrait de Nabucco et La donna è mobile de Rigoletto

Dopo oltre un secolo dalla loro creazione, le opere di Verdi dominano ancora il repertorio dell’arte lirica. Nabucco (1842), Rigoletto (1851) e Aida (composta in occasione dell’inaugurazione del Canale di Suez), tra le altre, sono entrate nell’olimpo dell’opera. Verdi’s Triumphs di Wil van der Beek raccoglie quattro temi molto popolari: la Marcia trionfale e Su! Del Nilo al sacro lido dall’Aida, il Coro degli Schiavi dal Nabucco e La donna è mobile dal Rigoletto.
