orchestra and orchestration definition of orchestra and orchestration in the Free Online Encyclopedia.

orchestra and orchestration, an orchestra is a musical ensemble of mixed instruments based on strings and winds, under the direction of a conductor, employing four classes of instruments: strings, woodwinds, brass, and percussion. It is the principal large instrument ensemble of Western music from the 18th to the 20th cent. Orchestration is the scoring of a piece of music so that it can be played by specific instruments.

Instruments of the Orchestra

The strings, except the harp, have several players for each part, the others usually only one. The strings are the bowed violin violin, family of stringed musical instruments having wooden bodies whose backs and fronts are slightly convex, the fronts pierced by two f-hole-shaped resonance holes.

The strings are the most important section of the orchestra; they are the most versatile and flexible and play almost continuously in most scores. The woodwinds are next in importance; they add color to the string sound and in some passages carry the melody. Of the brass, the French horn is the most useful, since it blends equally well with the woodwinds or the other brasses. The trumpets, trombones, and tuba are the "heavy artillery" of the orchestra; playing loudly, they provide a dynamic climax, but they are also effective in subdued passages as a group or individually.

The percussion instruments are used to emphasize rhythm. The kettledrums are most important, blending best with the rest of the orchestra and also being tunable to a definite pitch. The others stand out so prominently that they are most effective when used sparingly. The harp is principally a color instrument and does not share the importance of the bowed strings.

History

Early History of Orchestras and Orchestration

The orchestra in the modern sense of the word did not exist before the 17th cent. Previous instrumental ensemble music was chamber music, except for occasional ceremonies when as many instruments as were available would be massed together. Until well into the 17th cent. there was little thought of specifying what instrument should play a part; any available instrument with the proper range was used. The first known example of orchestration occurs in Giovanni Gabrieli's (see under Andrea Gabrieli Giovanni Gabrieli (jōvän`nē), c.1555–1612.

By the end of the century a division into four parts had become standard: first and second violins, violas, and cellos, with the double basses playing the cello part an octave lower. (Not until the 19th cent. did the cellos and basses frequently have different parts to play.)

Woodwinds appeared in the earliest orchestras, though infrequently and subordinate to the strings—usually two oboes and a bassoon, with flutes sometimes replacing the oboes. The flutes were established as regular orchestra members, playing together with the oboes, only late in the 18th cent. The trumpets, inseparable from the kettledrums through the 17th and 18th cent., were used occasionally in the 17th cent. and became standard in the orchestra by about 1700. The French horn was fully accepted by 1750. The trombone was used in church music even before the 17th cent. and occasionally in opera thereafter; it did not become a regular member of the symphony orchestra until after 1800.

Throughout the baroque period and into the second half of the 18th cent., the basso continuo was an integral part of the scoring and required that a harpsichord or some other chord-playing instrument fill in the harmonies above the figured bass figured bass, in music, a system of shorthand notation in which figures are written below the notes of the bass part to indicate the chords to be played. Called also thorough bass and basso continuo, it arose in the early 17th cent.

The Eighteenth-Century Classical Orchestra

During the latter half of the 18th cent. the classical orchestra was gradually established through the disuse of the continuo and the acceptance of the clarinet. The abandonment of the continuo led to much greater independence in the string parts, which now had to fill the harmony unaided. Instead of both violin parts doubling the melody and the violas, cellos, and basses doubling the bass, there were now four distinct parts. The clarinet, like the flute, first appeared as an alternate for the oboe, but in the late works of Haydn and Mozart the orchestra was standardized, with pairs of flutes, oboes, clarinets, bassoons, French horns, trumpets, and kettledrums in addition to the strings. All the wind instruments, especially the woodwinds, could carry the melody, providing desired changes of color.

Orchestras in the Nineteenth Century

In the 19th cent., beginning in the works of Beethoven, the brass took an increasingly prominent place. The trombone was used regularly, while the invention of the valve in 1813 soon made the horn and trumpet completely chromatic. All the brass thus became melody instruments, instantly available in the most remote keys. The horn section was increased to four early in the century, and the introduction of the tuba (c.1835–50) gave the brass a dependable contrabass register it had previously lacked. The woodwinds also were improved mechanically in the 19th cent., greatly enlarging their technical capabilities. Throughout the century the string section was expanded to balance the increasing numbers of wind players.

The scores of Mozart and Beethoven generally required an orchestra of about 40; those of Weber and early Wagner called for about 55; Wagner's Ring cycle (1854–74) called for about 110; and Strauss's Elektra for 115.

After the climax of orchestral bulk in the works of Wagner, Mahler, Strauss, and several others, composers reacted against orchestral gigantism, first in the impressionism impressionism, in music, a French movement in the late 19th and early 20th cent. It was begun by Debussy in reaction to the dramatic and dynamic emotionalism of romantic music, especially that of Wagner.

Innovations of the Twentieth Century

Stravinsky's Rite of Spring (1913) illustrates the early 20th-century interest in diverse instrumental combinations and original exploitation of the instruments' capabilities. In general, composers of the 20th cent. have continued exploring novel uses of instruments and have preferred a moderate-sized orchestra. Seventy-five to ninety players suffice for most 20th-century scores; a reduced, or chamber, orchestra of classical or baroque dimensions has also been much used. In this century the percussion section is used more prominently; new instruments have been devised and the playing of old ones varied.

Orchestras of Note

Among the world's many fine orchestras the following European ensembles have particular historic importance: the Leipzig Gewandhaus-Konzerte, not called by that name until later, began in 1743; the Philharmonic Society, London, was established in 1813; the Société des Concerts du Conservatoire, Paris, began in 1828; the Wiener Philharmonische Konzerte, Vienna, began in 1842; the Berlin Philharmonisches Orchester was established in 1882.

Among the oldest American orchestras still in existence are the New York Philharmonic-Symphony Orchestra New York Philharmonic-Symphony Orchestra, dating from 1842, the oldest symphony orchestra in the United States. Its present name derives from the merger (1928) of the New York Philharmonic Orchestra with the New York Symphony Orchestra.
