During the first weeks sounding like a drunk beer fiddler I strongly felt like adding trills to sound more baroque. And it helped me a lot to feel more baroque during my simplistic improvisations, which inspired me a lot. But I trilled with middle and index finger only, my ring finger couldn't do it.

Now, a year later I have started to train my ring finger on trills and it is now able to bravely keep up with my middle finger. And I already realize, this makes my ring finger generally stronger and faster. So this technically helps me a lot. I've already started to trill with the pinkie too, although it's really tough on the little man and he's soon exhausted. But I need a stronger pinkie, so the little man has to bear with it.

Everybody wants to vibrate—to me trilling really seems to be the true gold standard.
