as someone who used to sing a lot of opera can i tell you if you flub a word in italian and substitute it with different kinds of pasta NOBODY NOTICES
What if you forget an entire song?
My choir director loved to tell this story where she was in Italy singing in an Italian opera, and totally forgot the words, knowing that a horribly mean critic was watching. She just spewed a bunch of random Italian, and at one point ordered a pizza in Italian. The critic commented on her beautiful diction and connection to the text.
That is the most amazing diction substitution I’ve ever heard.
