This is Un moto di gioia, an aria for Susanna that Mozart later added to The Marriage of Figaro because the soprano at the time didn’t like the original one “Venite inginocchiatevi.” However, these days this aria is sung alone as a lied - possibly against Mozart’s wishes. It seems he had replaced the original aria because this one not only suited the soprano’s voice better, it is also easier to sing.
Funny to think, if Mozart would see a production of Figaro these days, he might go “Ach nein! That’s not how I wrote it!”
