Ken Hall, flute
Ken started playing the flute when he was 10 years old and has perversely continued to do so despite several close calls with much more practical careers. He received his Bachelor’s degree in flute from the University of Calgary, where he received the Fine Arts Faculty Gold Medal. His Master’s degree was at the University of Toronto, where he studied with Doug Stewart. In addition to studying performance, he dabbled with composition and musicology before coming to his senses.
In addition to his music, Ken worked as a professional landscaper, a nightclub bouncer (OK, just one shift), a music librarian, as a stage and production manager and as a concert organizer, before finding himself in increasingly responsible roles as an arts administrator. He worked for 16 years running the Canadian Children’s Opera Company in Toronto. He also took on increasingly irresponsible performance opportunities, culminating in his founding role with The Gemsmen – a medieval quartet concerned with playing rudimentary precursors to the recorder and singing drunkenly around mouthfuls of cheese.
Ken is a firm believer in the power of music to tell stories, and the power of stories to deepen a listener’s experience. He is an amateur photographer.
