Later composers affected by the Curse of the Ninth Symphony included Franz Schubert and Antonin Dvorak. It is now generally accepted that Schubert wrote nine symphonies, although two of them were not completed by the author (symphony No. 8, the so-called "Unfinished", consists of two completed parts and an outline of the third; the symphony in E major was written in full, but was never orchestrated). Dvorak wrote precisely nine symphonies, but the first of them was not performed by the orchestra during the author's lifetime and was not published; moreover, Dvorak himself considered her manuscript irretrievably lost. It is more or less obvious that neither Mahler nor Schoenberg had them in mind.

At present, those who recall the Curse of the ninth symphony cite a number of composers of the 20th century, whose symphonic work stopped at the ninth symphony. The most significant among these names are Ralph Vaughan Williams, Malcolm Arnold, Kurt Atterberg, Roger Sessions, Egon Welles. Alexander Glazunov in the second half of the 1900s began work on his ninth symphony, but postponed it after the completion of the first part and never returned to the idea, having lived for another two and a half decades. The ninth symphony was the last for Alfred Schnittke, who wrote it immediately before his death; in addition, Nikolai Korndorf, who at the request of Schnittke's widow, took up the reconstruction of the work, died during this work (this edition was completed by Alexander Raskatov and performed under the direction of Dennis Russell Davis; there is also an earlier and very different reconstruction by Gennady Rozhdestvensky).
Dmitri Shostakovich, starting to work on his Ninth Symphony, was mindful of historical precedents. After her, Shostakovich wrote six more. However, according to the musicologist Solomon Volkov, the Curse still overtook Shostakovich: the Ninth Symphony, with its scurrilous flavor, caused Stalin's sharp discontent, which was followed by major troubles in Shostakovich's life and career at the turn of the 1940s-1950s.

Of course, in the 20th century there were many other authors who wrote more than nine symphonies; among them, in particular, Hans Werner Henze and Eduard Tubin, David Diamond and Edmund Rabbra, Heitor Villa-Lobos and Darius Millau, Henry Cowell and Allan Pettersson, Moses Weinberg, Nikolai Myaskovsky, Alan Hovaness and others.
Nikita Bogoslovsky named his eighth symphony, written in the 1980s, "The Last". The composer claimed that he "said everything in the symphonic genre", but many felt that he was simply afraid to write the 9th symphony after the story with Beethoven. However, after the 8th symphony, Bogoslovsky also departed from songwriting, although he lived for another 20 years.
