What is this vocal technique called and any hints/links on how to master it?
Here is one example:
It sounds like a frequent type of vibrato. But searching web for "vibrato" ends up in the lessons for "less frequent" vibrato (like this: https://en.wikipedia.org/wiki/File:VIBRATO.ogg). Searching for "frequent vibrato" doesn't give good result either.
So maybe this vocal technique has its own name and I'll be glad to know it. Thank you!
