Knut Nystedt (3 September 1915 – 8 December 2014) was an orchestral and choral composer. He grew up in a Christian home where hymns and classical music were an important part of everyday life. His major compositions for choir and vocal soloists are mainly based on texts from the Bible or sacred themes. Old church music, especially Palestrina and Gregorian chants, have had a major influence on his compositions.
