Franz Joseph Haydn
Franz Joseph Haydn (31 March 1732 - 31 May 1809) was an Austrian composer of the Classical Period. He was a mentor of Mozart, and a tutor of Beethoven.
Haydn was crucial in the development of chamber music such as the piano trio (a trio with a pianist). He has been called the "Father of Symphony,""Father of the String Quartet," and "Papa Haydn."
Haydn’s compositions are known for his use of motif to create a larger work. His music played a large role in the development of sonata form. Haydn was also a court musician for the wealthy Esterhazy family at their remote estate, which is why his music tends to sound upbeat.
Haydn’s Symphony No. 94 in G Major is often called the "Surprise Symphony." Here is an excerpt from the second movement. The six eighth notes followed by a quarter note is a motif throughout this movement. See if you can find the "surprise" on this page.
