Symphonies

A symphony is a musical composition written for orchestra. It usually consists of multiple distinct sections or movements, often 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. Some symphonies also contain vocal parts, such as Beethoven's Ninth Symphony.
