One of the "Big Five" Russian composers of the romantic era, Пётр Ильич Чайковский (Tchaikovsky) was considered a very nationalist composer. Much of his music features traditional Russian melodies as themes.
Little known fact for people that aren't into classical music:
Tchaikovsky was gay but he tried to hide or repress who he was, and as a result suffered from depression. His depression stayed with him for much of his life, and he even attempted suicide on some occasions. His depression and internal conflict can be heard in a lot of his compositions. While his official cause of death is listed as cholera, many historians speculate that it was actually suicide to cover up a scandal.
I encourage anyone to attend the Stetson Chamber Orchestra concert this coming Tuesday, November 4th, in Lee Chapel. We will be performing Tchaikovsky's Serenade for Strings, a work in four movements.
