Instrumentation

Instrumentation

Classical and popular music are often distinguished by their choice of instruments. 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.

Aspects

Aspects

Classical music is considered primarily a written musical tradition, preserved in music notation, as opposed to being transmitted orally, by rote, or in recordings of particular performances. While there are differences between particular performances of a classical work, a piece of classical music is generally held to transcend any interpretation of it. The use of musical notation is an effective method for transmitting classical music, since the written music contains the technical instructions for performing the work. The written score, however, does not usually contain explicit instructions as to how to interpret the piece in terms of production or performance, apart from directions for dynamics, tempo and expression (to a certain extent); this is left to the discretion of the performers, who are guided by their personal experience and musical education, their knowledge of the work's idiom, and the accumulated body of historic performance practices.

However, improvisation once played an important role in classical music. A remnant of this improvisatory tradition in classical music can be heard in the cadenza, a passage found mostly in concertos and solo works, designed to allow skilled performers to exhibit their virtuoso skills on the instrument. Traditionally this was improvised by the performer; however more often than not, it is written for (or occasionally by) the performer beforehand.

Its written transmission, along with the veneration bestowed on certain classical works, has led to the expectation that performers will play a work in a way that realizes in detail the original intentions of the composer. During the 19th century the details that composers put in their scores generally increased. Yet the opposite trend — admiration of performers for new "interpretations" of the composer's work — can be seen, and it is not unknown for a composer to praise a performer for achieving a better realization of the composer's original intent than the composer was able to imagine. Thus, classical music performers often achieve very high reputations for their musicianship, even if they do not compose themselves. Generally however, it is the composers who are remembered more than the performers.

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.

Another consequence of the primacy of the composer's written score is that improvisation plays a relatively minor role in classical music, in sharp contrast to traditions like jazz, where improvisation is central. Improvisation in classical music performance was far more common during the Baroque era than in the nineteenth and twentieth centuries, and recently the performance of such music by modern classical musicians has been enriched by a revival of the old improvisational practices. During the classical period, Mozart and Beethoven sometimes improvised the cadenzas to their piano concertos (and thereby encouraged others to do so), but they also provided written cadenzas for use by other soloists.

Commercialism

Commercialism

Certain staples of classical music are often used commercially (that is, either in advertising or in the soundtracks of movies made for entertainment). In television commercials, several loud, bombastically rhythmic orchestral passages have become clichés, particularly the opening "O Fortuna" of Carl Orff's Carmina Burana; other examples in the same vein are the Dies Irae from the Verdi Requiem, Edvard Grieg's In the Hall of the Mountain King, and excerpts of Aaron Copland's "Rodeo".

Similarly, movies and television often revert to standard, clichéd snatches of classical music to convey refinement or opulence: some of the most-often heard pieces in this category include Mozart's Eine kleine Nachtmusik and Vivaldi's Four Seasons.

Complexity

Complexity

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.

Education

Education

Throughout history, parents have often made sure that their children receive classical music training from a young age. Some parents pursue music lessons for their children for social reasons or in an effort to instill a useful sense of self-discipline. Some consider that a degree of knowledge of important works of classical music is part of a good general education.

During the 1990s, several research papers and popular books emergence touting the so-called Mozart effect: a temporary, small elevation of scores on certain tests as a result of listening to Mozart. The popularized version of the controversial theory was expressed succinctly by a New York Times music columnist: "researchers have determined that listening to Mozart actually makes you smarter." Promoters marketed CDs claimed to induce the effect. Florida passed a law requiring toddlers in state-run schools to listen to classical music every day, and in 1998 the governor of Georgia budgeted $105,000 per year to provide every child born in Georgia with a tape or CD of classical music. One of the original researchers commented "I don't think it can hurt. I'm all for exposing children to wonderful cultural experiences. But I do think the money could be better spent on music education programs."

Emotion

Emotion

Autobiographies of composers reveal that some composers of classical music aspired to communicate a transcendent quality of emotion, what has been called the "sublime" in art.[citation needed] For example, Beethoven set Friedrich Schiller's poem, Ode to Joy in his 9th symphony. However, some composers, such as Iannis Xenakis, argue that the emotional effect of music on the listeners is arbitrary and therefore the objective complexity or informational content of the piece is paramount.[citation needed]

Popular music

Popular music

Classical music has often incorporated elements or even taken material from popular music. Examples include occasional music such as Brahms' use of student drinking songs in his Academic Festival Overture, genres exemplified by Kurt Weill's The Threepenny Opera, and the influence of jazz on early- and mid-twentieth century composers including Maurice Ravel, as exemplified by the movement entitled "Blues" in his sonata for violin and piano.[14] Certain postmodern, minimalist and postminimalist classical composers acknowledge a debt to popular music.[15]

There are, likewise, numerous examples of influence flowing in the opposite direction, including popular songs based on classical music, the use to which Pachelbel's Canon has been put since the 1970s, and the musical crossover phenomenon, where classical musicians have achieved success in the popular music arena (one notable example is the "Hooked on Classics" series of recordings made by the Royal Philharmonic Orchestra in the early 1980s).
