Canticum Calamitatis Maritimae ("Song of Maritime Calamity") is an eight-part, a cappella classical choral composition by the Finnish composer Jaakko Mäntyjärvi.
The text of the piece is taken from three sources: the Catholic Requiem Mass, Psalm 107: "They that go down to the sea in ships...", and the report of the disaster from the weekly Latin-language Finnish news service, Nuntii Latini.
After a lamenting, wordless soprano solo, the piece continues with the Nuntii Latini report, recited by a baritone or tenor cantor.
After this, the piece moves into the text of Psalm 107, in Latin: Qui descendunt mare in navibus, facientes operationem in aquis multis: 24 ipsi viderunt opera Domini, et mirabilia ejus in profundo.
Chords that occur late in the piece—set to the text "...et clamaverunt ad Dominum / cum tribularentur..." are sung in open, parallel fourths, suggesting funerary bagpipes.
The final words of the piece-- "requiem aeternam"—are voiced in the bass and soprano registers, suggesting foghorns and marine bells, respectively.
