The Maple Leaf Forever This rousing and patriotic song was written in 1867, the year of Canada’s Confederation. It became very popular and, for many years, was the unofficial national anthem of Canada. The piece opens with a “snare drum” passage played by the trombone and gradually introduces the theme in the horn while the trumpets play bugle calls. This introduction could serve as an opportunity for the choir to “march” into position and be ready for the chorus which appears at the key change. This arrangement is part of a collection for young musicians celebrating Canada’s 150th anniversary since joining Confederation.
