In the morning I thought about how to change the prepared lessons so that my voice was spared as much as possible. Everything bad is good for something. I needed to explain the polyphony and find an activity to rest my vocal cords. An idea was born. The class I was to teach was composed mostly of hockey players. They liked to show off and look for a moment to show themselves to the class.
