Music Beethoven Composed

How did beethoven’s musical composition during the “middle period” of his life differ from his other periods?
I have read that the music that Beethoven composed in his “middle period” differed from the other periods of composition of his life as it placed a strong emphasis on dynamics and also furthered the scope of the classical period of compositon at the time. Yet I would like to know how his music placed a strong emphasis on dynamics and how his music furthered the scope of classical music, if at all.
middle period of his life?
he was middle-aged, previously he had been younger, later he would become older.
