Here’s a list of five things you might not already know about the composer…

1. He taught the illustrious Beethoven. Their relationship was particularly difficult, owing to Beethoven’s suspicion of Haydn’s talent. The former once said “I never learned anything from Haydn.”
2. Many techniques and ideas used by later, more well-known composers can be found originally in his music.
3. A prolific composer, he wrote 104 symphonies, over 30 duos and around 90 string quartets (over 340 hours of music!).
4. His musical jokes extended to teaching musicians who were notoriously arrogant and vain a lesson. To one particular violinist, he gave him music that at first was simple to sight-read, but became horrifyingly difficult after the first page.
5. He was a sharp negotiator, and often bargained with publishers to receive higher fees for his compositions.
