  The String Sonata No. 1, commonly referred to by its original Italian name Sonata per archi, is a composition for string orchestra by German composer Hans Werner Henze. It was composed between 1957 and 1958.
  
  ## Composition
  
  The sonata was commissioned by Paul Sacher for his own orchestra, the Collegium Musicum Zürich, together with his Double Concerto for Oboe, Harp and Strings, and was written between 1957 and early 1958. According to Henze, it was influenced by an earlier idea of Heinz von Cramer, the librettist of Henze's König Hirsch, for a ballet about the Embarquement pour Cythère. It was premiered by Paul Sacher in Zurich on March 21, 1958. It was dedicated to Paul Sacher and his wife, Maya Sacher and was later published by B. Schotts' Sohne.

  Its structure is nothing like a traditional sonata and displays the composer's distinctive serialist style. The first movement consists of a five-minute Stravinskian toccata, with plenty neo-classical features. It starts in E minor, but modulates in minor-third oscillations. The second movement is presumably influenced by Beethoven and consists of a set of attacca variations which are very difficult to distinguish by ear. It is scored for eight first violins, six second violins, four violas , four celli and two double basses.
