Beethoven is considered the transitional figure between Classical composers Haydn and Mozart on the one hand, and the Romantics on the other. His innovations included his construction of his Sixth Symphony (The Pastoral) as program music and his expansion of the quartet, concerto, sonata, and symphony forms.
Ludwig van Beethoven showed great musical potential from early childhood. His father was overbearing, abusive and an alcoholic. After his father's death, Beethoven supported his family as a musician. When his ill mother died, Beethoven was sent into a deep depression for several years. He suffered many such bouts of depression throughout his lifetime.
