Reddit reviews The Bach Cello Suite No. 1 Study Book

You’ll get good advice from others- probably lift your elbow round etc etc.

But, this book is excellent- https://www.amazon.com/Bach-Cello-Suite-Study-Book/dp/1635230187

and, look into low tension strings. Holy shit I wish someone had told me that at uni. Life saver for people with little fingers.

And finally, think about the melodic contour/timbre you want; should it be a brighter sound, so A string, or do you need a mellow warmer D string tone? Are you breaking up the phrasing by changing strings or shifting?

Edit: nycellist to the rescue (that happens often on this sub!)- perhaps low gauge strings rather than low tension. I love my low tension strings but it might actually be the gauge rather than the tension that makes the playing easier.
