Tchaikovsky

Piotr Tchaikovsky was born in Votinsk in 1840. He was the son of a mining engineer and his mother was of French ancestry. At a very early age it was obvious that he had a great musical talent and so from the age of five he was given piano lessons. Later, he studied at the St Petersburg Conservatory and later still, he became the professor of theory and harmony at the newly founded Moscow Conservatory. He held the post until 1878.
In 1877 Tchaikovsky married a young student called Antonina Milyukova, but it was not a happy marriage. Soon after the wedding he tried to kill himself by walking into an icy river, but he survived and only nine weeks after his wedding day he left his wife and never lived with her again. However, Tchaikovsky was still a married man when he died as he and Antonina never got a divorce.
For fourteen years Tchaikovsky corresponded with a wealthy widow, Nadezhda von Meck. She insisted that they never meet; though they did accidentally encounter each other on a couple of occasions, but did not speak. As well as her regular financial support, Nadezhda von Meck was very supportive of Tchaikovsky’s musical career and admired his work. However, she suddenly cut off her support for Tchaikovsky for no obvious reason, although it is widely believed that she was unhappy with Tchaikovsky’s behaviour. She may also have hoped to marry one of her daughters to him, but after his previous unsuccessful marriage he refused. In addition, he was deeply upset by the withdrawal of her money for, although he no longer needed the money, he did still need her moral support. Von Meck also tried to marry another of her daughters to the family’s music teacher – a certain French composer called Debussy.
Just nine days after the first performance of his Sixth Symphony, the Pathétique, in St Petersburg in 1893, Tchaikovsky died suddenly. He was buried at the Alexander Nevsky Monastery in St Petersburg.
