Di quella pira is a popular tenor aria (or more specifically cabaletta) sung by Manrico in Act 3, Scene 2 of Giuseppe Verdi’s opera, Il trovatore.
In a chamber adjoining the chapel at Castellor, Leonora and Manrico vow their love for each other. After Manrico’s aria Ah si, ben mio coll’essere(“Ah, yes, my love, in being yours”), they are about to take their marriage vows. However, Ruiz, Manrico’s comrade, suddenly returns to report that Manrico’s mother Azucena is to be burned at the stake. Manrico calls together his soldiers and sings of how they will save Azucena from death: “Di quella pira l’orrendo foco tutte le fibre m’arse avvampò!…” (“The horrible blaze of that pyre burns, enflames all of my being!…”)
