Published by Galaxy Music Corporation - Digital (MQ.1.3500-E). English.Commissioned by the Minnesota Valley Men's Chorale, Invictus should be sung with rhythmic intensity and a growing sense of urgency. The chorale that concludes the work should be sung with a sense of unity and triumph. The writing is powerful but not overly complex. Henley's poem was written in 1875, and it has been quoted and used by such dignitaries as Winston Churchill, Nelson Mandela, and Barack Obama. Duration 3:00.
