Wagner's influence

The Budapest Symphony Orchestra.
The next major expansion of symphonic practice came from Richard Wagner's Bayreuth orchestra, founded to accompany his musical dramas. Wagner's works for the stage were scored with unprecedented scope and complexity: indeed, his score to Das Rheingold calls for six harps. Thus, Wagner envisioned an ever-more-demanding role for the conductor of the theater orchestra, as he elaborated in his influential work "On Conducting".[8] This brought about a revolution in orchestral composition, and set the style for orchestral performance for the next eighty years. Wagner's theories re-examined the importance of tempo, dynamics, bowing of string instruments and the role of principals in the orchestra. Conductors who studied his methods would go on to be influential themselves.

History of the orchestra

 Early history

Image of an Assyrian Orchestra, from a slab in the British Museum, dating from 7th century BC. There are 7 portable harps, a dulcimer, two double reed-pipes(aulos), and a drum.
The modern orchestra has its historical roots in Ancient Egypt. The first orchestras were made up of small groups of musicians that gathered for festivals, holidays or funerals. During the time of the Roman Empire, the government suppressed the musicians and informal ensembles were banned[why?], but they reappeared after the collapse of the Empire. It was not until the 11th century that families of instruments started to appear with differences in tones and octaves. True modern orchestras started in the late 16th century when composers started writing music for instrumental groups. In the 15th and 16th centuries in Italy the households of nobles had musicians to provide music for dancing and the court, however with the emergence of the theatre, particularly opera, in the early 17th century, music was increasingly written for groups of players in combination, which is the origin of orchestral playing. Opera originated in Italy, and Germany eagerly followed. Dresden, Munich and Hamburg successively built opera houses. At the end of the 17th century opera flourished in England under Henry Purcell, and in France under Lully, who with the collaboration of Molière also greatly raised the status of the entertainments known as ballets, interspersed with instrumental and vocal music....
In the 17th century and early 18th century, instrumental groups were taken from all of the available talent. A composer such as Johann Sebastian Bach had control over almost all of the musical resources of a town, whereas Handel would hire the best musicians available. This placed a premium on being able to rewrite music for whichever singers or musicians were best suited for a performance—Handel produced different versions of the Messiah oratorio almost every year.
As nobility began to build retreats away from towns, they began to hire musicians to form permanent ensembles. Composers such as the young Joseph Haydn would then have a fixed body of instrumentalists to work with. At the same time, travelling virtuoso performers such as the young Wolfgang Amadeus Mozart would write concerti that showed off their skills, and they would travel from town to town, arranging concerts along the way. The aristocratic orchestras worked together over long periods, making it possible for ensemble playing to improve with practice.

 Mannheim School

This change, from civic music making where the composer had some degree of time or control, to smaller court music making and one-off performance, placed a premium on music that was easy to learn, often with little or no rehearsal. The results were changes in musical style and emphasis on new techniques. Mannheim had one of the most famous orchestras of that time, where notated dynamics and phrasing, previously quite rare, became standard (see Mannheim school). It also attended a change in musical style from the complex counterpoint of the baroque period, to an emphasis on clear melody, homophonic textures, short phrases, and frequent cadences: a style that would later be defined as classical.
Throughout the late 18th century composers would continue to have to assemble musicians for a performance, often called an "Academy", which would, naturally, feature their own compositions. In 1781, however, the Leipzig Gewandhaus Orchestra was organized from the merchants concert society, and it began a trend towards the formation of civic orchestras that would accelerate into the 19th century. In 1815, Boston's Handel and Haydn Society was founded, in 1842 the New York Philharmonic and the Vienna Philharmonic were formed, and in 1858, the Hallé Orchestra was formed in Manchester. There had long been standing bodies of musicians around operas, but not for concert music: this situation changed in the early 19th century as part of the increasing emphasis in the composition of symphonies and other purely instrumental forms. This was encouraged by composer critics such as E. T. A. Hoffmann who declared that instrumental music was the "purest form" of music. The creation of standing orchestras also resulted in a professional framework where musicians could rehearse and perform the same works repeatedly, leading to the concept of a repertoire in instrumental music.

 Performance standards

In the 1830s, conductor François Antoine Habeneck, began rehearsing a selected group of musicians in order to perform the symphonies of Beethoven, which had not been heard of in their entirety in Paris. He developed techniques of rehearsing the strings separately, notating specifics of performance, and other techniques of cuing entrances that were spread across Europe. His rival and friend Hector Berlioz would adopt many of these innovations in his touring of Europe.

 Instrumental craftsmanship

The invention of the piston and rotary valve by Heinrich Stölzel and Friedrich Blühmel, both Silesians, in 1815, was the first in a series of innovations, including the development of modern keywork for the flute by Theobald Boehm and the innovations of Adolphe Sax in the woodwinds. These advances would lead Hector Berlioz to write a landmark book on instrumentation, which was the first systematic treatise on the use of instrumental sound as an expressive element of music.[7]
The effect of the invention of valves for the brass was felt almost immediately: instrument-makers throughout Europe strove together to foster the use of these newly refined instruments and continuing their perfection; and the orchestra was before long enriched by a new family of valved instruments, variously known as tubas, or euphoniums and bombardons, having a chromatic scale and a full sonorous tone of great beauty and immense volume, forming a magnificent bass. This also made possible a more uniform playing of notes or intonation, which would lead to a more and more "smooth" orchestral sound that would peak in the 1950s with Eugene Ormandy and the Philadelphia Orchestra and the conducting of Herbert von Karajan with the Berlin Philharmonic.
During this transition period, which gradually eased the performance of more demanding "natural" brass writing, many composers (notably Wagner and Berlioz) still notated brass parts for the older "natural" instruments. This practice made it possible for players still using natural horns, for instance, to perform from the same parts as those now playing valved instruments. However, over time, use of the valved instruments became standard, indeed universal, until the revival of older instruments in the contemporary movement towards authentic performance (sometimes known as "historically informed performance").
At the time of the invention of the valved brass, the pit orchestra of most operetta composers seems to have been modest. An example is Sullivan's use of two flutes, one oboe, two clarinets, one bassoon, two horns, two cornets (a piston), two trombones, drums and strings.
During this time of invention, winds and brass were expanded, and had an increasingly easy time playing in tune with each other: particularly the ability for composers to score for large masses of wind and brass that previously had been impractical. Works such as the Requiem of Hector Berlioz would have been impossible to perform just a few decades earlier, with its demanding writing for twenty woodwinds, as well as four gigantic brass ensembles each including around four trumpets, four trombones, and two tubas.

About Orchestra




Orchestra

An orchestra is a sizable instrumental ensemble that contains sections of string, brass, woodwind, and percussion instruments. The term orchestra derives from the Greek ορχήστρα, the name for the area in front of an ancient Greek stage reserved for the Greek chorus. The orchestra grew by accretion throughout the eighteenth and 19th centuries, but changed very little in composition during the course of the 20th century.

century

A smaller-sized orchestra for this time period (of about fifty players or fewer) is called a chamber orchestra. A full-size orchestra (about 100 players) may sometimes be called a "symphony orchestra" or "philharmonic orchestra"; these modifiers do not necessarily indicate any strict difference in either the instrumental constitution or role of the orchestra, but can be useful to distinguish different ensembles based in the same city (for instance, the London Symphony Orchestra and the London Philharmonic Orchestra). A symphony orchestra will usually have over eighty musicians on its roster, in some cases over a hundred, but the actual number of musicians employed in a particular performance may vary according to the work being played and the size of the venue. A leading chamber orchestra might employ as many as fifty musicians; some are much smaller than that. Orchestras can also be found in schools.

schools
Instrumentation

The typical symphony orchestra consists of four proportionate groups of similar musical instruments called the woodwinds, brass, percussion, and strings, and also the fifth proportionate group of similar musical instruments like the rhythm section in modern times. The orchestra, depending on the size, contains almost all of the standard instruments in each group. In the history of the orchestra, its instrumentation has been expanded over time, often agreed to have been standardized by the classical period[1] and Beethoven's influence on the classical model.[2]model

The history of computer development is often referred to in reference to the different generations of computing devices. Each generation of computer is characterized by a major technological development that fundamentally changed the way computers operate, resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices. Read about each generation and the developments that led to the current devices that we use today.

First Generation (1940-1956) Vacuum Tubes

The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.
First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.
The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.

Second Generation (1956-1963) Transistors

Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output.
Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology.
The first computers of this generation were developed for the atomic energy industry.

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers.
Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.

Fourth Generation (1971-Present) Microprocessors

The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer—from the central processing unit and memory to input/output controls—on a single chip.
In 1981 IBM introduced its first computer for the home user, and in 1984 Apple introduced the Macintosh. Microprocessors also moved out of the realm of desktop computers and into many areas of life as more and more everyday products began to use microprocessors.
As these small computers became more powerful, they could be linked together to form networks, which eventually led to the development of the Internet. Fourth generation computers also saw the development of GUIs, the mouse and handheld devices.

Fifth Generation (Present and Beyond) Artificial Intelligence

Fifth generation computing devices, based on artificial intelligence, are still in development, though there are some applications, such as voice recognition, that are being used today. The use of parallel processing and superconductors is helping to make artificial intelligence a reality. Quantum computation and molecular and nanotechnology will radically change the face of computers in years to come. The goal of fifth-generation computing is to develop devices that respond to natural language input and are capable of learning and self-organization.
