At the end of my last term taking Mandarin in my undergrad at UBC, I was drafted by my Chinese teachers to lead two groups in the Chinese Bridge Singing contest. This was one of those groups!
My uncle was kind enough to record a guitar track for us to sing over. I then sent my group members sample tracks of the melody and harmony, and instructions on how to film their videos from home! I spent many hours editing our parts together (I didn't mind, as this part I quite enjoy!) and sent it off.
Our entry won the award for best editing.
