O Canada for Clarinet Choir/Quartet

"O Canada" was originally written for the 1880 Saint-Jean-Baptiste Day Celebration in Québec. French-Canadian musician Calixa Lavallée composed the music, while the French lyrics were written by the poet Adolphe-Basile Routhier. The original English lyrics were written by Robert Stanley Weir in 1908. Having been the de facto national anthem of Canada since 1939, "O Canada" was officially made the country’s national anthem on July 1, 1980.

This clarinet choir arrangement includes parts for E♭ clarinet, 3 B♭ clarinets, bass clarinet, and contrabass clarinet. This version can also be played as a quartet if the E♭ and contra parts are omitted.
