Denmark and its multiple outlying islands have a wide range of folk traditions. The country's most famous classical composer is Carl Nielsen (1865–1931), especially remembered for his six symphonies and his Wind Quintet, while the Royal Danish Ballet specialises in the work of the Danish choreographer August Bournonville. The Royal Danish Orchestra is among the world's oldest orchestras. Danes have distinguished themselves as jazz musicians, and the Copenhagen Jazz Festival has acquired international recognition.
