Metamorphosen

Metamorphosen, study for 23 solo strings (TrV 290, AV 142) is a composition by Richard Strauss 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 on 25 January 1946 by Sacher and the Collegium Musicum Zürich, with Strauss conducting the final rehearsal.

==Composition history== By 1944, Strauss was in poor health and needed to visit the Swiss spa at Baden near Zürich. But he was unable to get the Nazi government's permission to travel abroad. Karl Böhm, Paul Sacher, and Willi Schuh came up with a plan to get the travel permit: a commission from Sacher and invitation to the premiere in Zurich. The commission was made in a letter by Böhm on August 28, 1944, for a "suite for strings". Strauss replied that he had been working for some time on an adagio for 11 strings. In fact, his early work on Metamorphosen was for a septet (2 violins, 2 violas, 2 cellos and a bass). The starting date for the score is given as 13 March 1945, which suggests that the destruction of the Vienna opera house the previous day gave Strauss the impetus to finish the work and draw together his previous sketches in just one month (finished on 12 April 1945).
