Mozart's arrangement of Handel's Messiah, made in 1789, relates to his involvement in the circle of musical connoisseurs surrounding the Baron Gottfried van Swieten, Viennese nobleman and aficionado of the monuments of Baroque music. It is, as the booklet here aptly puts it, a "cover version" (the German participle, charmingly enough, is "gecovert") of Handel's work, neither a radical rethinking nor a light rescoring. Mozart adds a good deal of wind scoring, often arranging things so that the winds peek out with a wink toward the end of an aria.
