Asa Dawson Thank you! Honestly for vibrato all I can say is find what you like, emulate it, and do that with every note on your instrument. Listen to cellists and violinists, and see if that sort of vibrato appeals to you and see how they achieve that (i.e. arm speed, hand shape, use of fingers, etc.) Every note should sound exactly how you want it. Same thing goes for tone. I approach by not being scared to mess up, and not being scared of hanging out near the bridge 😉
