Beethoven's hearing deteriorated from his late twenties. He first shared his fears about it in two letters to friends, written around 29th June, 1801. For some months he stayed in a village outside Vienna in the hope of his hearing improving, but in October 1802 he expressed his feelings of utter despair about deafness to his brothers in a letter found after his death known as the 'Heiligenstadt Testament'.
Beethoven was composing at a time of huge political, social and artistic change in Europe, during and post-French Revolution. During this time, artists and musicians worked and developed their ideas much more freely. Beethoven's music shows the influence of this, mainly in the style of his composition which breaks down some of the constraints of the Classical period. He experiments much more than previous composers in his use of keys and the development of the sonata form - he uses drama and expression much more intensely than previous composers.
When Beethoven wrote his Third Symphony, the 'Eroica', he dedicated it to Napoleon because he respected liberty and fraternity which Napoleon had originally appeared to stand for during the French Revolution. However, in a famous incident, when Napoleon was crowned Emperor, Beethoven is said to have been so dismayed that he crossed out the dedication.
Even though his music was highly regarded and he socialised with the aristocracy, Beethoven suffered from constant money problems. At points during his life, he tried to organise benefit concerts to earn some money. You can hear a re-creation of one of these concerts, held at the Theater an der Wien on 22nd December 1808, at the end of The Beethoven Experience, on Friday 10th June at 21.15.
Beethoven also had a difficult relationship with his family, and towards the end of his life, was involved in a bitter dispute to become the legal guardian of his nephew, Karl, after his brother's death.
Beethoven died in 1827.
