Haydn (1732.3.31-1809.5.31) was an Austrian composer. Born in the countryside, he received enlightenment in music since the age of 6. At the age of 8, he became a church choir boy and learned knowledge of culture and music. 1758-1766 He served as the Earl's Court Music Commissioner in 1999. A large number of musical works were created at this time. He went to England twice in 1791 and 1794 to conduct an orchestra and compose music. Received an honorary doctorate in music from Oxford University in London.

Haydn is one of the representatives of the Vienna Classical Music School. His works are extensive and vast, covering all fields of vocal music and instrumental music. The early works were undergoing a transformation from Baroque to classical style. Since then, a large amount of musical practice gradually formed the musical form of modern symphonies and quartets, and the dual-controlled orchestra system based on the four parts of strings. After the 1990s, his creation reached a state of perfection. The music has a rigorous structure and vibrant rhythm, and has typical style characteristics of classical music.

Haydn's main works include: 108 symphonies, 2 piano concertos, 2 violin concertos, 2 cello concertos, 2 horn concertos, 5 violin concertos with wheels, 8 organ concertos, 82 string quartets, 30 piano trios, 125 hippies, 56 string trios, 52 keyboard sonatas, 5 variations, 20 operas, 6 oratorios, 8 cantatas, 14 masses, and a large number of choruses, songs and song transformations.
