Making the rolling noise when pronouncing some words...

Question

For example, "rubia". Is it necessary to make that rolling noise when pronouncing the "r"? If you don't know what I mean, skip to 4:00 of this video...

Answer 1

Yes, it's necessary to roll the first "R" of a word and also when you see "RR" present.
