Ex. 5-1: Et Exultavit

From Bach's Magnificat in D major (BWV 243). The first version was likely composed for 2 July 1723 — Bach's first feast day after leaving his court position to become Thomaskantor in Leipzig. A revised version in D major followed around 1733; the key was changed to suit the natural trumpets, which were usually tuned in D in Saxony.

"Et exultavit spiritus meus in Deo salutari meo" (And my spirit has rejoiced in God my Savior) is the second movement, a soprano aria.
