A symphony is a musical composition, often extended and usually for orchestra. "Symphony" does not imply a specific form. Many symphonies are tonal works in four movements with the first in sonata form, and this is often described by music theorists as the structure of a "classical" symphony, although even some symphonies by the acknowledged classical masters of the form, Joseph Haydn, Wolfgang Amadeus Mozart and Ludwig van Beethoven, do not conform to this model. The cute bee making a great symphony in the garden, move your mouse following the flowers and the bee, you will enjoy the music it created.
