Which musical characteristic of Beethovens symphonies is the most moving to the listener?
You would have a choice of rhythmic drive which does impress listeners. Motivic unity also impresses the listener. There is a lot of psychological progression in all Beethoven’s works and I believe that it is the most moving. The rhymic drive is heard first in his symphonies, the motivic unity is by the end of the opening movements and the psychological progression comes after all the symphony’s movements have been experienced.
