Gustav Mahler: Symphony No.10 (Study Score)
Just as the Payne/Elgar Symphony No. 3 is not Edward Elgar's definitive statement, Mahler did not complete a Symphony No. 10. He did, however, leave 'a work fully prepared in the sketch,' the complete unorchestrated musical material. Had he lived, Mahler would almost certainly have shaped the material further. This means that the performance edition prepared by Deryck Cooke in the early 1960s is not a completion, it's an orchestration of the short score left at Mahler's death in 1911. It nevertheless sounds very 'complete,' both in itself and as a summation of the romantic-epic 19th century German musical tradition.
