Conceived thirty years apart, both works on the present disc came into being at difficult times in the life of Arnold Schoenberg. Emotional stress caused by a marital crisis around 1907-1908 is often claimed to have contributed to the break with tonality that the Second String Quartet represents – in the course of the work Schoenberg moves from the post-Wagnerian chromaticism of Late Romanticism to atonality, with the final movement lacking a key signature altogether. Another unusual feature is the inclusion of a soprano in the two last movements. Schoenberg himself later wrote: 'I was inspired by poems of Stefan George, the German poet ... and, surprisingly, without any expectation on my part, these songs showed a style quite different from everything I had written before.' Almost thirty years later, in 1936, the String Quartet No. 4 was one of the first works that Schoenberg composed in the U.S.A. after having been forced into exile by the threat of the * regime in Germany. He had left Europe in 1933, but the first years in his new home country had been taxing, with health problems and a difficult work schedule involving teaching in both Boston and New York. If the second quartet is a key work of musical modernism, pointing towards an as yet unknown future, String Quartet No. 4 rests securely on the principles of twelve-tone composition that Schoenberg had developed during the intervening years – but makes use of these principles in a somewhat freer, more relaxed manner than his previous twelve-tone works. The two works are given full-blooded performances by the Gringolts Quartet, joined by the Swedish soprano Malin Hartelius in the Second String Quartet.
