Verklärte Nacht is a string sextet by Austrian composer Arnold Schönberg, composed in 1899 and revised in 1917. Scored for two violins, two violas and two cellos, the work blends late-Romantic chromatic harmony and dense string textures that presage Schönberg's later move towards atonality, occupying a transitional place in his early career and in the development of early 20th-century chamber music.
