Check out the 2021 Fiddlerman “White Christmas” Group Project.
I am splitting practice time between violin and cello alternating one hour each. What I am finding is that a muscle in my right shoulder tires very quickly when bowing the cello. I have some 10 pound weights that I am now using to help beef up that muscle. I don't know if it will help but it's all I know to do except of course to just keep bowing.
The very beautiful sound I first heard on this cello is sounding less beautiful as I now become accustomed to the sound of the strings. I have a new set of strings coming, but I will be looking for my permanent strings. I noticed that Fiddlerman is now selling his own line of strings for violin. A Fiddlerman string set for cello would be a nice thing.
Of course I don't know if it's correct but,,,,I rotated the bow stick so that the hair is below the stick (the hair is at an angle to the string) and trying to allow gravity to pull the bow into the strings. That seems to work. My shoulder is able to relax while bowing. It will take concentrated practice to make a habit of it.
