was a late-Romantic Danish composer and organist. His then-unconventional music was at odds with that of his Danish contemporaries but was recognized 16 years after his death.
Rued Langgaard composed in a late Romantic style, emphatically dramatic and endowed with colossal mood swings. Unquestionably, he was influenced by Richard Wagner and Richard Strauss and, like Strauss, he was a master of orchestration. He was a prolific composer for the large orchestra, writing 16 symphonies as well as other orchestral works.
Music of the Spheres is his best-known and most radical work. It is a symphonic work of great complexity, calling for a large orchestra including organ and a piano on which the strings are played directly rather than via the keys, choir, and a supporting (distant) orchestra including a soprano voice. It was composed during World War I, but only performed twice (in Germany in 1921–1922) during Langgaard's lifetime and lay dormant for almost 50 years before being rediscovered. When it was rediscovered in the late 1960s, it was considered remarkably modern and reflective of the pathfinding style in which Langgaard composed. In 2010 Music of the Spheres received its British premiere at The Proms, conducted by Thomas Dausgaard.
His unorthodox style and sense of drama extended to the titles of his compositions. His fourth and sixth symphonies are known as the Leaf Fall and Heaven Storming. His symphonies Nos. 13 and 16 are named Faithlessness and Deluge of Sun, respectively. Examples of descriptive names for individual movements are Wireless Caruso and Compulsive Energy and Daddies rushing off to the Office (in symphony No. 14, The Morning).
His total production of over 400 works included more than 150 songs, works for piano, organ, and an opera entitled Antikrist (The Antichrist).
