Ludwig van Beethoven
Beethoven went deaf at the turn of the century. Apparently, he could not always hear what he played. After 1819 CE, all conversations with him had to be written down.
Like Mozart, Vivaldi died in poverty, in an unmarked grave. Both composers were similar in how they achieved greatness in their composition and popularity, yet failed to secure financial greatness.
Instrumental in forging a distinctly American style of composition, he was widely known as “the dean of American composers.”
Franz Joseph Haydn
This Austrian composer played a large hand in crafting classical music during his time. He composed 106 symphonies and cast a long shadow for other composers to live under. One of his most famous pupils was, in fact, Beethoven.
Peter Ilyich Tchaikovsky
A Russian composer from St. Petersburg, Tchaikovsky produced some very memorable pieces, including Swan Lake and Piano Concerto No. 1. Interesting fact: he hated writing The Nutcracker, undoubtedly his most famous work.
