I love this use of the word "proprio" in Mozart's Don Giovanni. Mozart operas are mostly in Italian, so they are cool way of testing out some of your vocab.
Here's the clip, go to 2hrs 40min where the band starts playing from another opera "Cosa rara". Proprio is used here by the manservant Leporello describing how Don G is really going to pass out from choking to death engorging himself on his food. https://youtu.be/aL2VdxseTvE Buon appetito!
