This is the foundation on which all your cello playing rests and getting it right is more important than most people appreciate. Spend all of the time you need to figure this out so that your time on the cello is spent in comfort and ease. In the I Luv Cello Hello Cello course, I address this subject multiple times with different exercises. This is my first lesson on posture and I hope it gives you a good start and moves you a step forward to playing the cello! Remember that the time spent on good posture and holding the cello and bow correctly is worth the effort and will pay dividends in the future in the form of less stress on your body, ease of playing, playing ability, and quality of the sound you produce.
