Some years ago while watching a local muso work an unamplified room the following happened. He was doing old fashioned banjo - what I call "English Music Hall" 'plain' style banjo - no fancy picking, but he seems to be able to do that, just not the style he likes.

Loud chatter. He started off so soft that he was not heard, then built up to very loud. Suddenly he went very soft, and the whole room shut up and all eyes swivelled to him. He had them in the palm of his hamd with nmo chatter for the rest of the bracket.

It's called technique.
