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.
My violin is a 3/4 violin, made for right-handed players, though I play it left-handed. As I felt she was the best in the shop of all 3/4 violins I tried and the luthier agreed. I prefer Obligato strings together with Eudoxa E string. Self-made bow, weight: 24 g / 0.85 oz
