Answer
Composed in 1997, Sofia Gubaidulina's "Canticle of the Sun" is a choral work that sets to music the text of St. Francis of Assisi's "Canticle of the Creatures." The piece is characterized by its use of polyphony, dissonance, and extended vocal techniques, creating a rich and evocative soundscape that reflects the beauty and wonder of the natural world celebrated in the text.
