If the central musical form for solo instruments during the Classical period was the sonata, its orchestral counterpart was the symphony.
symphony
the most obvious predecessor to the symphony as we know it now is the ‘sinfonia,’ the Italian opera overture of previous centuries.
the symphony has various origins according to historians
Operaovertures
written around 1700 had musical material independent
of the opera they were meant to introduce and were often written in such a way that they could be performed as individual pieces, without the orchestra.
symphony
The form originated in Italy around the year 1730.
Many of the first symphonies were written by composers working in Milan and the surrounding parts of northern Italy.
From Italy, the form spread throughout the rest of Europe, reaching as far as Germany and England.
Most notable of these developments outside of Italy was that in Mannheim.
Giovanni Battista Sammartini
Most prominent composer of symphonies
Mannheim
is a city in southwest Germany
it was home to the Mannheim orchestra.
Johann Stamitz
Bohemian composer
Under his baton, the Mannheim orchestra became known all over Europe for its discipline, as well as its unprecedented use of dynamics.
The orchestra was able to produce the cleanest pianissimi and fortissimi, and used crescendi to such great effect that they became known for the Mannheim crescendo.
Stamitz was the first known composer to have consistently composed in what is now the standard structure for symphonies.
Stamitz’s symphonies
all contained four movements
The third movements of his symphonies were all composed in minuet and trio form.
The last movements, furthermore, were all written in fast tempi, most often using the tempo marking “presto.”
