L.v.B. Chamber Orchestra 52nd Concert

There are several types of composers: Mozart and Schubert are fast writers and prolific composers, while Brahms and Bruckner often revise their works even after they have completed them.
Mozart is a typical example of a fast-writing composer who composed an opera in a few days, but "Paris Symphony" is a rare work that took a lot of time to elaborate, perhaps because he had a new market in mind.

The "Paris Symphony" is a rare work that took a long time to elaborate, perhaps with an eye to a new market.
Nowadays, there are few opportunities to perform the overture No. 2, but it is a deeply moving work when one thinks of the story of the hardships involved in revising it and making it into the overture No. 3. The overture at the premiere, which was a disaster, was "No. 2," the revised version was "No. 3," "No. 1" was composed for the Prague performance, and "No. 2" was revised for the final performance. In the final draft, Beethoven himself changed the title to "Fidelio" and the overture was also changed to "Fidelio" Overture, which is a long story.

Then there is Brahms' Symphony No. 1.
By 1876, when Brahms' First Symphony, which took 21 years to complete, was to be Beethoven's successor, Schubert, Mendelssohn, and Schumann had already passed away, Bruckner composed his Fourth Symphony (1874), Dvořák his Fifth Symphony (1875), Tchaikovsky his Third Symphony (1875), and Wagner his "Lowenburg" (1876). Wagner wrote "Lohengrin" (1848) and "Die Meistersinger von Nuremberg" (1867). However, if we listen to them as "works from the heyday of Romanticism" rather than "works that are an extension of the Classical period," we will find a different view of the music. If you listen to it as "a work of the heyday of Romanticism" rather than "an extension of the Classical period," you will see a different view.
