Symphony No. 94 (Haydn)

The Symphony No. 94 in G major (H. 1/94) is the second of the twelve so-called London symphonies written by Joseph Haydn. It is popularly known as the Surprise Symphony.

Date of composition

Haydn wrote the symphony in 1791 in London for a concert series he gave during the first of his visits to England (1791–1792). The premiere took place at the Hanover Square Rooms in London on March 23, 1792, with Haydn leading the orchestra seated at a fortepiano.

Scoring

The Surprise Symphony is scored for a Classical-era orchestra consisting of two each of flutes, oboes, bassoons, horns, trumpets, plus timpani, and the usual string section consisting of violins (first and second), violas, cellos, and double basses.

A typical performance of the Surprise Symphony lasts about 23 minutes.

Nickname (the Surprise)

Haydn's music contains many jokes, and the Surprise Symphony includes probably the most famous of all: a sudden fortissimo chord at the end of the otherwise piano opening theme in the variation-form second movement. The music then returns to its original quiet dynamic, as if nothing had happened, and the ensuing variations do not repeat the joke. (In German it is commonly referred to as the Symphony "mit dem Paukenschlag"—"with the kettledrum stroke").
