Ludwig van Beethoven (born December 16, 1770-March 26, 1827) was a German composer and pianist. He was a crucial figure in the transitional period between the Classical and Romantic eras in Western classical music, and remains one of the most acclaimed and influential composers of all time. He moved to Vienna in his early twenties and settled there, studying with Joseph Haydn and quickly gaining a reputation as a virtuoso pianist. His hearing began to deteriorate in the late 1790s, yet he continued to compose, conduct, and perform, even after becoming completely deaf.
In "Ocean's Three and a Half", he is seen working on the "Ode to Joy" segment of the 9th Symphony.
The scene of Brian in the chair in "Once Bitten" is a parody of A Clockwork Orange, complete with the "Ode to Joy" from Beethoven's 9th Symphony.
