Without exception, the typical classical
symphony begins with a sonata form movement. In the hands of Beethoven the
form becomes exceptionally elongated, much to the consternation of some of
his contemporaries. Development of short motives is one of his most notable
traits.
The Theme and Variation was an ideal
form for the classicist who sought to create a movement with limited means.
After a theme was presented, the composer then runs the theme through a series
of permutations called variations. In each variation the theme was discernible,
yet the composer was free the vary the harmony, rhythm, orchestration, or
countless other musical elements. It was popularly used in the second movement,
though it could also appear in the forth as well.
The minuet was always used in the
third movement of a traditional classical symphony. Beethoven was no traditionalist
however. Beginning with Beethoven the minuet is replaced with a scherzo. Where
the minuet was elegant, the scherzo was fast and furious. No doubt, it better
captured the flavor of the revolutionary age.
The rondo was a popular way to end
a symphony. The composer opens with a theme in which he then moves away from
to a contrasting theme. After returning to the opening theme, again the composer
moves away to state a new contrasting theme. This process can continue as
long as the composer desires - stating news thematic ideas after always returning
to the original opening theme.

Recapitulation
P' ~ ~ S' ~ ~

An
optional section to the form, here the composer presents a slow introduction
as a dramatic precursor to the opening Exposition.
|
Opens
with a statement of the Primary theme followed by a contrasting Secondary
theme in the dominate key. The Exposition is always played twice.
|
Here
the composer develops the themes first presented in the Exposition by
changing keys, harmony, orchestration, etc.
|
A
restatement of the Exposition. The Recapitulation provides a symmetrical
balance to the form.
|
Technically
optional, but effectively always there, the coda extends to form long
enough for the composer to round out the work with a good ending.
