Chamber Symphony (Enescu)

The Chamber Symphony, Op. 33, in E major, is a symphony written for twelve instruments, and the last work finished by the Romanian composer George Enescu.
History.
The earliest ideas eventually taken up in the Chamber Symphony date back to a sketch for a septet for winds and piano, dating from around the time of the Octet for strings, Op. 7 (1900). The score is dated May 1954, a year before his death but less than two months before Enescu suffered the cerebral stroke in July that made all work impossible. The final markings to the score had to be dictated to Marcel Mihalovici. The score is dedicated to the Association of Chamber Music Concerts of Paris and its permanent conductor Fernand Oubradous.
The work was performed for the first time in a concert commemorating the first anniversary of the composer's death, at the Romanian Athenaeum in Bucharest. Constantin Silvestri conducted the performance and, when it received only a tepid response from the audience, announced, "This work is Enescu's masterpiece; it is more difficult to grasp than others, because of its very advanced language. Therefore, we shall perform it once more in its entirety." After this second hearing, it was a great success .
Instrumentation.
The work is scored for twelve instruments: flute, oboe, cor anglais, clarinet, bassoon, horn, trumpet, violin, viola, cello, doublebass, and piano.
