Classical music

Classical music is a broad term that usually refers to music produced in, or rooted in the traditions of Western liturgical and secular music, encompassing a broad period from roughly the 9th century to present times.[1] The central norms of this tradition became codified between 1550 and 1900, which is known as the common practice period.

Characteristics
Given the extremely broad variety of forms, styles, genres, and historical periods generally perceived as being described by the term "classical music," it is difficult to list characteristics that can be attributed to all works of that type.

Vague descriptions are plentiful, such as describing classical music as anything that "lasts a long time," a statement made rather moot when one considers contemporary composers who are described as "classical;" or music that has certain instruments like violins, which are also found in bluegrass music, Broadway music, and other genres; or "relaxing" or "background" music for affluent people, descriptions which are probably only accurate when describing court music from the Baroque and Classical periods; indeed, many people do not find modern or avant-garde composers and works such as Threnody to the Victims of Hiroshima by Krzysztof Penderecki or Black Angels by George Crumb to be very relaxing or "snobby."

However, there are characteristics that classical music contains that generally few or no other genres of music contain.

[edit] Instrumentation
Classical and popular music are often distinguished by their choice of instruments. There are few if any genres in which so many different instruments are used simultaneously by performing groups such as symphony orchestras, which often contain as many as 5 or so different types of string instruments including members of the violin family and harp, 7 or more types of woodwind instruments, 4 or so types of brass instrument, and many diverse percussion instruments, sometimes as many as 10 different types. Also prevalent, especially in opera, is the human voice. Comparatively, most popular music genres involve fewer instruments. For instance a typical rock band will consist of a drummer, a guitarist or two, a singer or two, an electric bassist and, less universally, a keyboardist. Of course, crossover influences, such as string sections in pop recordings, are very popular as well, but rarely are backing strings considered to be part of pop or rock bands.

The instruments used in common practice classical music were mostly invented before the mid-19th century (often much earlier), and codified in the 18th and 19th centuries. They consist of the instruments found in an orchestra, together with a few other solo instruments (such as the piano, harpsichord, and organ).

Electric instruments such as the electric guitar appear occasionally in the classical music of the 20th and 21st centuries. Both classical and popular musicians have experimented in recent decades with electronic instruments such as the synthesizer, electric and digital techniques such as the use of sampled or computer-generated sounds, and the sounds of instruments from other cultures such as the gamelan.

None of the bass instruments existed until the Renaissance. In Medieval music, instruments are divided in two categories: loud instruments for use outdoors or in church, and quieter instruments for indoor use. Many instruments which are associated today with popular music used to have important roles in early classical music, such as bagpipes, vihuelas, hurdy-gurdies and some woodwind instruments. On the other hand, the acoustic guitar, for example, which used to be associated mainly with popular music, has gained prominence in classical music through the 19th and 20th centuries.

While equal temperament became gradually accepted as the dominant musical temperament during the 19th century, different historical temperaments are often used for music from earlier periods. For instance, music of the English Renaissance is often performed in mean tone temperament.

[edit] Form and technical execution
Whereas the majority of popular styles, such as rock music, lend themselves to the song form, classical music can also take on the form of the concerto, symphony, opera, dance music, suite, etude, symphonic poem, and others.

Classical composers often aspire to imbue their music with a very complex relationship between its affective (emotional) content and the intellectual means by which it is achieved. Many of the most esteemed works of classical music make use of musical development, the process by which a musical germ, idea or motif is repeated in different contexts or in altered form. The classical genres of sonata form and fugue employ rigorous forms of musical development.

Along with a certain desire for composers to attain high technical achievement in writing their music, performers of classical music are faced with similar goals of technical mastery, as demonstrated by the proportionately high amount of schooling and private study most successful classical musicians have had when compared to "popular" genre musicians, and the large number of secondary schools, including the conservatories, dedicated to the study of classical music. The only other genre in the Western world with comparable secondary education opportunities is jazz.

[edit] Complexity
Classical music generally requires high musical skills to play such as sight reading, ability to coordinate with other players and experience in playing the composer's music. Classical works often display musical complexity through the composer's use of development, modulation (changing of keys), variation rather than exact repetition, musical phrases that are not of even length, counterpoint, polyphony and sophisticated harmony. Larger-scale classical works (such as symphonies, concertos, operas and oratorios) are built up from a hierarchy of smaller units: namely phrases, periods, sections, and movements. Musical analysis often seeks to distinguish and explain these structural levels.

[edit] Society
Often perceived as opulent or signifying some aspect of upper-level society, classical music has generally never been as popular with working class society. However, the traditional perception that only upper-class society has access to and appreciation for classical music, or even that classical music represents the upper-class society, may not be true, given that many if not most working classical musicians fall somewhere in the middle-class income range in the United States, and that classical concertgoers and CD buyers are not necessarily upper class.[citation needed]. Even in the Classical era, Mozart's opera buffa such as Cosi fan Tutte were popular with many common people.

Classical music regularly features in Pop Culture forming background music for movies, television programs and advertisements. As a result most people in the Western World regularly and often unknowingly listen to classical music, this means that it can be argued that the relativly low levels of CD sales may not be a good indicator of its actual popularity. In more recent times the association of certain classical pieces with major events has led to brief upsurgens in interest in particular classical genres. A good example of this was the choice of Nessun Dorma from Puccini's opera Turandot as the theme tune for the 1990 Soccer World Cup which led to a noticeable increase in popular interest in opera and in particular in tenor arias, which led to the huge sellout concerts by The Three Tenors. Such events are often cited as helping to drive increases in the audiences at many classical concerts that have been observed in recent times.
