100 in G major, Hoboken I/100, is the eighth of the twelve London symphonies written by Joseph Haydn and completed in 1793 or 1794.
The nickname "Military" derives from the second movement (and the end of the finale), which features prominent fanfares written for C-trumpets and percussion effects.
One reviewer wrote after the premiere that the second movement evoked the "hellish roar of war increas[ing] to a climax of horrid sublimity!
The tutti then transitions the music to the dominant key for the second subject area, which begins with the first theme transposed to D major.
It is the only movement that uses divided violas and clarinets, but most importantly is the use of "Turkish" instruments (triangle, cymbals and bass drum) which make their first appearance in the central minor section.
[4] The movement concludes with an extended coda featuring a bugle call for solo trumpet, a timpani roll, which was a revolutionary adaptation of the instrument, and a loud outburst in A♭ major.
