Franz Joseph Haydn

Symphony No. 100 in G Major
Military Symphony

Haydn's Symphony No. 100 in G Major is in four Movements. A brief description of the work can be found here.

1.	Adagio - Allegro
2.	Allegretto
3.	Minuetto - Moderato
4.	Presto

The first movement, Adagio - Allegro, is in the sonata-allegro form, which is common to 18th century music.

Sonata-Allegro Form

A typical sonata-form movement consists of a two-part tonal structure, articulated in three main sections. The first section, exposition, is divided into a 'first group' in the tonic key and, after transitional material, a 'second group' in another key (usually the dominant key in major movements, the relative major in minor ones), often with a coda to round out the section. Both groups may include a number of different themes. In 18th-century music the exposition is almost always directed to be repeated.

The second part of the structure comprises the remaining two sections, the 'development' and 'recapitulation'. The first usually develops material from the exposition in a variety of ways, moving through a number of keys. Compared with the exposition, this section is usually one of considerable tonal instability and of rhythmic and melodic tension. It also prepares the structural climax, the 'double return' to the main theme and to the tonic key which begins the recapitulation. This final section restates the themes of the exposition, usually in the same order; the second group is then heard in the tonic (possibly tonic major if the movement is minor), and there may be temporary excursions to other keys. Before 1780 the second part (development and recapitulation) was usually directed to be repeated. After that date this repetition became increasingly rare.
