The Fourth Symphony of the German composer Karl Amadeus Hartmann is a work for string orchestra.
It was derived in part from an earlier Concerto for strings and soprano written in 1938.
Hartmann revised the work to include a new purely instrumental third and closing movement, marked Adagio appassionato.
The second movement, Adagio di molto, risoluto, contains several references to Hartmann's own First String Quartet of 1933.
The work was premiered in this form by the Bavarian Radio Symphony Orchestra under Hans Rosbaud[2] in Munich on 2 April 1948, chronologically before the premiere of his Third Symphony.
