The Symphony No. 9 in C major, D. 944, known as the Great (published in 1840 as “Symphony No. 7 in C Major”, listed as No. 8 in the Neue Schubert-Ausgabe), is the final symphony completed by Franz Schubert. Originally called The Great C major to distinguish it from his Symphony No. 6, the Little C major, the subtitle is now usually taken as a reference to the symphony's majesty. Unusually long for a symphony of its time, a typical performance of The Great takes around 55 minutes, though it can also be played in as little as 45 minutes by employing a faster tempo and not repeating sections as indicated in the score.
For a long time, the symphony was believed to be a work of Schubert’s last year, 1828. It was true that, in the last months of his life, he did start drafting a symphony – but this was the work in D major now accepted as Symphony No. 10, which has been realized for performance by Brian Newbould. In fact, it is now known that the 'Great' was largely composed in sketch in the summer of 1825: that, indeed it was the work to which Schubert was referring in a letter of March 1824 when he said he was preparing himself to write 'a grand symphony' (originally listed as Gmunden-Gastein symphony, D 849 in the Deutsch Catalogue). By the spring or summer of 1826 it was completely scored, and in October, Schubert, who was quite unable to pay for a performance, sent it to the Gesellschaft der Musikfreunde with a dedication. In response they made him a small payment, arranged for the copying of the orchestral parts, and at some point in the latter half of 1827 gave the work an unofficial play-through (the exact date and the conductor are unknown) – though it was considered too long and difficult for the amateur orchestra of the conservatory.
A recent hypothesis suggests that the symphony may have received its first performance on 12 March 1829 in a Concert spirituel at the Landständischer Saal in Vienna. The evidence for this hypothesis is slender, however, and it contradicts contemporary sources which prove that Schubert's Symphony No. 6 (also in C major) was performed at this instance. In 1836 Schubert's brother Ferdinand attempted to perform the final movement alone, yet there is no proof that it was actually played in public.
