"Verklärte Nacht (Transfigured Night), Op. 4, is a string sextet in one movement composed by Arnold Schoenberg in 1899. Composed in just three weeks, it is considered his earliest important work. It was inspired by Richard Dehmel's poem of the same name, combined with the influence of Schoenberg's strong feelings upon meeting Mathilde von Zemlinsky (the sister of his teacher Alexander von Zemlinsky), whom he would later marry. The movement can be divided into five distinct sections which refer to the five stanzas of Dehmel's poem; however, there are no unified criteria regarding movement separation. Metamorphosen, study for 23 solo strings (TrV 290, AV 142) is a composition by Richard Strauss, scored for ten violins, five violas, five cellos, and three double basses, typically lasting 25 to 30 minutes. It was composed during the closing months of the Second World War, from August 1944 to March 1945. The piece was commissioned by Paul Sacher, the founder and director of the Basler Kammerorchester and Collegium Musicum Zürich, to whom Strauss dedicated it. It was first performed in 25 January 1946 by Sacher and the Collegium Musicum Zürich, with Strauss conducting the final rehearsal." (Wiki).
