History


Baroque and classical eras

In the Baroque era, the size and composition of an orchestra was not standardised. There were large differences in size, instrumentation and playing styles—and therefore in orchestral soundscapes and palettes — between the various European regions. The ''Baroque orchestra'' ranged from smaller orchestras (or ensembles) with one player per part, to larger scale orchestras with many players per part. Examples of the smaller variety were Bach's orchestras, for example in Koethen, where he had access to an ensemble of up to 18 players. Examples of large scale Baroque orchestras would include Corelli's orchestra in Rome which ranged between 35 and 80 players for day-to-day performances, being enlarged to 150 players for special occasions. In the classical era, the orchestra became more standardized with a small to medium-sized string section and a core wind section consisting of pairs of oboes, flutes, bassoons and horns, sometimes supplemented by percussion and pairs of clarinets and trumpets.


Beethoven's influence

The so-called "standard complement" of doubled winds and brass in the orchestra pioneered in the late 18th century and consolidated during the first half of the 19th century is generally attributed to the forces called for by

20th-century orchestra

At the beginning of the 20th century, symphony orchestras were larger, better funded, and better trained than previously; consequently, composers could compose larger and more ambitious works. The works of
Gustav Mahler Gustav Mahler (; 7 July 1860 – 18 May 1911) was an Austro-Bohemian Romantic composer, and one of the leading conductors of his generation. As a composer he acted as a bridge between the 19th-century Austro-German tradition and the modernism ...
were particularly innovative; in his later symphonies, such as the mammoth Symphony No. 8, Mahler pushes the furthest boundaries of orchestral size, employing huge forces. By the late Romantic era, orchestras could support the most enormous forms of symphonic expression, with huge string sections, massive brass sections and an expanded range of percussion instruments. With the recording era beginning, the standards of performance were pushed to a new level, because a recorded symphony could be listened to closely and even minor errors in intonation or ensemble, which might not be noticeable in a live performance, could be heard by critics. As recording technologies improved over the 20th and 21st centuries, eventually small errors in a recording could be "fixed" by audio editing or
overdubbing Overdubbing (also known as layering) is a technique used in audio recording in which audio tracks that have been pre-recorded are then played back and monitored, while simultaneously recording new, doubled, or augmented tracks onto one or more av ...
. Some older conductors and composers could remember a time when simply "getting through" the music as best as possible was the standard. Combined with the wider audience made possible by recording, this led to a renewed focus on particular star conductors and on a high standard of orchestral execution.

Organization

Among the instrument groups and within each group of instruments, there is a generally accepted hierarchy. Every instrumental group (or section) has a principal who is generally responsible for leading the group and playing orchestral solos. The violins are divided into two groups, first violin and second violin, with the second violins playing in lower registers than the first violins, playing an
accompaniment Accompaniment is the musical part which provides the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles o ...
part, or harmonizing the melody played by the first violins. The principal first violin is called the concertmaster (or orchestra "leader" in the U.K.) and is not only considered the leader of the string section, but the second-in-command of the entire orchestra, behind only the conductor. The concertmaster leads the pre-concert tuning and handles musical aspects of orchestra management, such as determining the bowings for the violins or for all of the string section. The concertmaster usually sits to the conductor's left, closest to the audience. There is also a principal second violin, a principal viola, a principal cello, and a principal bass. The principal trombone is considered the leader of the low brass section, while the principal trumpet is generally considered the leader of the entire brass section. While the oboe often provides the tuning note for the orchestra (due to a 300 year-old convention), there is generally no designated principal of the woodwind section (though in woodwind ensembles, the flute is often the presumptive leader.) Instead, each principal confers with the others as equals in the case of musical differences of opinion. Most sections also have an assistant principal (or co-principal or associate principal), or in the case of the first violins, an assistant concertmaster, who often plays a

with the rest of the section, except in the case of divided (''divisi'') parts, where upper and lower parts in the music are often assigned to "outside" (nearer the audience) and "inside" seated players. Where a solo part is called for in a string section, the section leader invariably plays that part. The section leader (or principal) of a string section is also responsible for determining the bowings, often based on the bowings set out by the concertmaster. In some cases, the principal of a string section may use a slightly different bowing than the concertmaster, to accommodate the requirements of playing their instrument (e.g., the double-bass section). Principals of a string section will also lead entrances for their section, typically by lifting the bow before the entrance, to ensure the section plays together. Tutti wind and brass players generally play a unique but non-solo part. Section percussionists play parts assigned to them by the principal percussionist. In modern times, the musicians are usually directed by a conductor, although early orchestras did not have one, giving this role instead to the concertmaster or the

Performances

In the Baroque era, orchestras performed in a range of venues, including at the fine houses of aristocrats, in opera halls and in churches. Some wealthy aristocrats had an orchestra in residence at their estate, to entertain them and their guests with performances. During the Classical era, as composers increasingly sought out financial support from the general public, orchestra concerts were increasingly held in public

s, where music lovers could buy tickets to hear the orchestra. Aristocratic patronage of orchestras continued during the Classical era, but this went on alongside public concerts. In the 20th and 21st century, orchestras found a new patron: governments. Many orchestras in North America and Europe receive part of their funding from national, regional level governments (e.g., state governments in the U.S.) or city governments. These government subsidies make up part of orchestra revenue, along with ticket sales, charitable donations (if the orchestra is registered as a charity) and other fundraising activities.

Issues in performance


Faking

One of the "great unmentionable opicsof orchestral playing" is " faking", the process by which an orchestral musician gives the false "... impression of playing every note as written", typically for a very challenging passage that is very high or very fast, while not actually playing the notes that are in the printed music part. An article in ''

'' states that all orchestral musicians, even those in the top orchestras, occasionally fake certain passages. One reason that musicians fake is because there are not enough rehearsals. Another factor is the extreme challenges in 20th century and 21st century contemporary pieces; some professionals said "faking" was "necessary in anything from ten to almost ninety per cent of some modern works". Professional players who were interviewed were of a consensus that faking may be acceptable when a part is not written well for the instrument, but faking "just because you haven't practised" the music is not acceptable.

Recent trends in the United States

In the United States, the late 20th century saw a crisis of funding and support for orchestras. The size and cost of a symphony orchestra, compared to the size of the base of supporters, became an issue that struck at the core of the institution. Few orchestras could fill auditoriums, and the time-honored season-subscription system became increasingly anachronistic, as more and more listeners would buy tickets on an ''ad-hoc'' basis for individual events. Orchestral endowments and — more centrally to the daily operation of American orchestras — orchestral donors have seen investment portfolios shrink, or produce lower yields, reducing the ability of donors to contribute; further, there has been a trend toward donors finding other social causes more compelling. While government funding is less central to American than European orchestras, cuts in such funding are still significant for American ensembles. Finally, the drastic drop in revenues from recording, related to changes in the recording industry itself, began a period of change that has yet to reach its conclusion. U.S. orchestras that have gone into Chapter 11 bankruptcy include the

Along with a decrease in funding, some U.S. orchestras have reduced their overall personnel, as well as the number of players appearing in performances. The reduced numbers in performance are usually confined to the string section, since the numbers here have traditionally been flexible (as multiple players typically play from the same part).

During the Classical music period (), the practice of using chordal instruments to play basso continuo was gradually phased out, and it disappeared completely by 1800. Instead, ensembles began to use conductors to lead the orchestra's tempos and playing style, while the concertmaster played an additional leadership role for the musicians, especially the string players, who imitate the bowstroke and playing style of the concertmaster, to the degree that is feasible for the different stringed instruments.
