Yes, we all read.
However the information was incomplete. Movt 3 of what? You mentioned a "song". Beethoven wrote an opera, a mass, 9 symphonies and 32 sonatas, all have "movements". We are pretty well informed but telepaths are in short supply.
No need to shout. Just provide the necessary information.
Then I suggest you save us sometime and do a search. This particular movement of this particular sonata is one of the most discussed pieces in ths forum.
Best wishes,
Bernhard.
