The fact is that there was no decline, our musical tradition was healthy right up until the end. There was a large circle of composers in National Socialist Germany, we know this because of surviving fragments of the Gottbegnadeten list. Most of their sheet music is lost or locked away in archives, and it would be career suicide for a soloist to perform their works.

Let's take a concrete example of a composer from National Socialist Germany, in this case a Russian-Polish composer who has squeezed past the blacklist in recent years.

>The Piano Sonata No 2, Op 60, was premiered by Bortkiewicz in the Brahms-Saal of the Musikverein in Vienna on 29 November 1942, during a Bortkiewicz Sonatenabend, in which Jaro Schmied (violin) and Paul Grümmer (cello) also participated. During the composer’s lifetime the piano sonata was played only by Hugo van Dalen, for the first time on 8 February 1944 in Amsterdam, and Felicitas Karrer in Vienna. It was a great success with both audience and critics.

This 1942 piano sonata is better than anything ever composed in America and better than anything ever composed by a Jew, and yet it was a fairly unremarkable piece in Nazi Germany.
