JOSEPH HAYDEN wrote this song its not really very long symphony surprise he said number 94 kings and queens all came to see who this wonderous man could be la la la la la big BOOM la la la la
Haydn's 94th symphony gained the nickname of the "Surprise" because of the loud chord in the second movement that blasts through the delicate "twinkle twinkle little star" theme.
Haydn wrote the song because he was tired of people falling asleep at his concerts so he wrote a nice song with soft music at the begining then it turned into a loud song
