Frederik Reesen Magle (Danish pronunciation: [ˈfʁeðˀʁek ˈmɑwlə]; born 17 April 1977) is a Danish composer, concert organist, and pianist. He writes contemporary classical music as well as fusion of classical music and other genres. His compositions include orchestral works, cantatas, chamber music, and solo works (mainly for organ), including several compositions commissioned by the Danish Royal Family. Magle has gained a reputation as an organ virtuoso, and as a composer and performing artist who does not refrain from venturing into more experimental projects – often with improvisation – bordering jazz, electronica, and other non-classical genres.
His best-known works include his concerto for organ and orchestra The Infinite Second, his brass quintet piece Lys på din vej (Light on your path), composed for the christening of Prince Nikolai, The Hope for brass band and choir, his symphonic suite Cantabile, and a collection of improvisations for organ titled Like a Flame.
