"Dona Nobis Pacem" (Ecclesiastical Latin: [ˈdona ˈnɔbis ˈpatʃɛm]) is a song with Latin text, often sung as a canon. The words, which mean "Grant us peace", come from the Latin Mass. The origin of the melody is unknown (most hymnals list it as "traditional"): it is sometimes attributed to Giovanni Pierluigi da Palestrina (Palestrina), though numerous sources attribute it to Mozart.[1]
