The Symphony No. 104 in D major (Hoboken 1/104) is Joseph Haydn's final symphony. It is the last of the twelve so-called London Symphonies, and is known (somewhat arbitrarily, given the existence of eleven others) as the London Symphony.
The work was composed by Haydn while he was living in London in 1795, and premiered there at the King’s Theatre on May 4, 1795, in a concert consisting entirely of Haydn's own compositions and directed by the composer. [1] The premiere was a success; Haydn wrote in his diary "The whole company was thoroughly pleased and so was I. I made 4000 gulden on this evening: such a thing is possible only in England."
The Symphony No. 94 in G major (Hoboken 1/94) is the second of the so-called twelve London symphonies (numbers 93-104) written by Joseph Haydn. It is usually called by its nickname, the Surprise Symphony. The work is among the most popular of Haydn's symphonies and is frequently performed and recorded.
