Symphony

Type of extended musical composition

A symphony is an extended musical composition in Western classical music, most often for orchestra. Although the term has had many meanings from its origins in ancient Greece, by the late 18th century the word had taken on the meaning common today: a work typically consisting of multiple distinct sections or movements, often three or four, with the first movement in sonata form. Symphonies are almost always scored for an orchestra consisting of a string section (violin, viola, cello, and double bass), brass, woodwind, and percussion instruments which altogether number about 30 to 100 musicians.
