When Mozart’s fiancée Constance Weber fell seriously ill in 1783 Mozart swore to God that if she recovered he would compose a major Mass to give thanks. When she recovered Mozart started to compose the Mass but for some reason or another he never completed it. He wrote the the Kyrie, Gloria, Sanctus and Benedictus and parts of the Credo but not the remainder of the Mass. Notwithstanding the fact that it’s incomplete it’s a major – and wonderful, piece of music with a distinctly operatic tinge.
I really don’t know where to start in listing its highpoints if I had to pick just one section of it I suppose it would have to be the adagio passage for chorus in the Gloria ‘Gratias agimus tibi propter gloriam tuam’ (We give thanks to you for your great glory), but then if I did that I’d miss the serenely beautiful soprano duet at ‘Domine deus, rex celestis’ (Lord God, heavenly King), and that’s just from the Gloria. Far better to just revel in the whole thing. It’s performed below at a concert given on Friday October 24th 2014 by the Orchestra of the Eighteenth Century with soloists Ilse Eerens [soprano], Rosanne van Sandwijk [mezzosoprano], Ben Heijnen [tenor], and Pierre-Guy Le Gall White [bas] conducted by Daniel Reuss. Enjoy :-).
