symphony

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 the ancient Greek era, by the late 18th century the word had taken on the meaning common today: a work usually consisting 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. Symphonies are notated in a musical score, which contains all the instrument parts. Orchestral musicians play from parts which contain just the notated music for their own instrument. Some symphonies also contain vocal parts (e.g., Beethoven's Ninth Symphony). Etymology and origins The word symphony is derived from the Greek word, meaning "agreement or concord of sound", "concert of vocal or instrumental music", from, "harmonious". The word referred to a variety of different concepts before ultimately settling on its current meaning designating a musical form. In late Greek and medieval theory, the word was used for consonance, as opposed to, which was the word for "dissonance". In the Middle Ages and later, the Latin form symphonia was used to describe various instruments, especially those capable of producing more than one sound simultaneously. Isidore of Seville was the first to use the word symphonia as the name of a two-headed drum, and from to 1377 the French form symphonie was the name of the organistrum or hurdy-gurdy. In late medieval England, symphony was used in both of these senses, whereas by the 16th century it was equated with the dulcimer. In German, Symphonie was a generic term for spinets and virginals from the late 16th century to the 18th century. In the sense of "sounding together," the word begins to appear in the titles of some works by 16th- and 17th-century composers including Giovanni Gabrieli's Sacrae symphoniae, and Symphoniae sacrae, liber secundus, published in 1597 and 1615, respectively; Adriano Banchieri's Eclesiastiche sinfonie, dette canzoni in aria francese, per sonare, et cantare, Op. 16, published in 1607; Lodovico Grossi da Viadana's Sinfonie musicali, Op. 18, published in 1610; and Heinrich Schütz's Symphoniae sacrae, Op. 6, and Symphoniarum sacrarum secunda pars, Op. 10, published in 1629 and 1647, respectively.
