Meet the The British-Iranian cellists Leila and Sara Shirvani

If you’re working on a composition that you can’t seem to get right, point out the passages and work on it in small portions instead of playing it as a whole. You may not get it right for any of the passages which could probably lead to frustration. Thus, identify the problem(s) you’re experiencing for each passage and play slowly until you feel confident to play it on a normal or required speed.
