It was great to hear of Emily Burridge's (1982) success of giving YCIS Hong Kong masterclasses through the Zoom platform. 

She writes:"Initially I received videos from everyone of the piece they wanted to work on so I was able to analyse each individual's technique prior to the class. They all had around 25-30 mins in the end - 3 hours with a break for questions - originally YCIS planned for 20 mins." More can be seen in this video which has been produced by YCIS Hong Kong.
