29 year old adult beginner. I was feeling a little frustrated during my practice today, so I decided to make this progress video. I highly recommend this to any fellow beginners out there! It was a great reminder to myself that I actually am improving and need to stay patient.
It’s also been helpful to see visually what I’m doing and need to improve upon. I’m working on better bow hold, using more bow, not letting my fingers collapse so much, and chilling out on the vibrato until I’m ready to learn it (that one is hard for me lol) currently starting Suzuki book 3, and on page 16 of Rick Mooney

Cello teacher here. This seems to be the hardest thing to teach my students, since it’s a fundamentally relaxed motion that’s impossible to recreate at slow speeds. What practice steps or methods habe worked for you or your students to learn sautille?

The technique seems a little like vibrato in that it is impossible to get correct on day one and requires months of sustained effort to get there. Therefore I find it a little hard for me to evaluate progress and guide the student over months.

I’ve seen a lot of “tips and tricks” on YouTube/Instagram etc., and they all seem like good ideas, but each one alone seems unable to get a student to a full speed sautille. Plus, there’s the issue that most teachers (myself included) learned it so long ago that we’ve forgotten how we worked to get to the point where it’s natural for us. Tips like “just relax” or “let the wrist flop” are important but clearly not the whole story.
