Nulla in mundo pax sincera, RV 630, is a sacred motet composed by Antonio Vivaldi in 1735 to an anonymous Latin text[citation needed], the title of which may be translated as "In this world there is no honest peace" or "There is no true peace in this world without bitterness". Written in the key of E major and in the typical lyrical Italian Baroque style[citation needed], it is scored for solo soprano, two violins, viola and basso continuo, this would normally be a cello and keyboard instrument, in Vivaldi's case often the organ[citation needed]. The text dwells on the imperfections of a world full of evil and sin, and praises Jesus for the salvation he offers from it. It is considered[by whom?] to be one of Vivaldi's most beautiful solo motets.[citation needed]
The motet consists of three parts (Aria; Recitative; Aria), followed by a concluding Alleluia. A full performance of the piece takes approximately 13 minutes.
