Contra-alto Clarinet
The contra-alto clarinet is a large clarinet pitched a perfect fifth below the B♭ bass clarinet. It is a transposing instrument in E♭ sounding an octave and a major sixth below its written pitch, between the bass clarinet and the B♭ contrabass clarinet. The contra-alto clarinet is often used in clarinet choirs and ensembles of clarinets and saxophones. It may also be present in a wind band. The repertoire for contra-alto clarinet in the symphony orchestra is limited. In ensembles it is usually used in unison with the other woodwind instruments, such as (bassoon, bass clarinet and contrabass clarinet), or it plays the lower octave in addition. History The contra-alto clarinet is largely a development of the 2nd half of the 20th century, although there were some precursors in the 19th century: * In 1829, , an instrument maker in Göttingen, introduced an instrument tuned in F in the shape and fingering of a basset horn, which could be called a horn because it played ...

Wind Instrument
A wind instrument is a musical instrument that contains some type of resonator (usually a tube) in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at or near the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece, while yet others require the player to blow into a hole at an edge, which splits the air column and creates the sound. Methods for obtaining different notes * Using different air columns for different tones, such as in the pan flute. These instruments can play several notes at once. * Changing the length of the vibrating air column by changing the length of the tube through engaging valves ''(see rotary valve, piston valve)'' which route the air through additional tubing, ...

Metal
A metal () is a material that, when polished or fractured, shows a lustrous appearance, and conducts electrical resistivity and conductivity, electricity and thermal conductivity, heat relatively well. These properties are all associated with having electrons available at the Fermi level, as against nonmetallic materials which do not. Metals are typically ductile (can be drawn into a wire) and malleable (can be shaped via hammering or pressing). A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polythiazyl, polymeric sulfur nitride. The general science of metals is called metallurgy, a subtopic of materials science; aspects of the electronic and thermal properties are also within the scope of condensed matter physics and solid-state chemistry, it is a multidisciplinary topic. In colloquial use materials such as steel alloys are referred to as metals, while others such as polymers, wood or ceramics are nonmetallic ...

Rock Music
Rock is a Music genre, genre of popular music that originated in the United States as "rock and roll" in the late 1940s and early 1950s, developing into a range of styles from the mid-1960s, primarily in the United States and the United Kingdom. It has its roots in rock and roll, a style that drew from the black musical genres of blues and rhythm and blues, as well as from country music. Rock also drew strongly from genres such as electric blues and folk music, folk, and incorporated influences from jazz and other styles. Rock is typically centered on the electric guitar, usually as part of a rock group with electric bass guitar, drum kit, drums, and one or more singers. Usually, rock is song-based music with a Time signature, time signature and using a verse–chorus form; however, the genre has become extremely diverse. Like pop music, lyrics often stress romantic love but also address a wide variety of other themes that are frequently social or political. Rock was the most p ...

Neue Musik
Neue Musik (English ''new music'', French ''nouvelle musique'') is the collective term for a wealth of different currents in composed Western art music from around 1910 to the present. Its focus is on compositions of 20th century music. It is characterised in particular by – sometimes radical – expansions of tonal, harmonic, melodic and rhythmic means and forms. It is also characterised by the search for new sounds, new forms or new combinations of old styles, which is partly a continuation of existing traditions, partly a deliberate break with tradition and appears either as ''progress'' or as ''renewal'' (neo- or post-styles). Roughly speaking, Neue Musik can be divided into the period from around 1910 to the Second World War – often referred to as "modernism" – and the reorientation after the Second World War, which is perceived as "radical" – usually apostrophised as ''avant-garde'' – up to the present. The latter period is sometimes subdivided into the 1950s, 1960s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neoclassicism
Neoclassicism, also spelled Neo-classicism, emerged as a Western cultural movement in the decorative arts, decorative and visual arts, literature, theatre, music, and architecture that drew inspiration from the art and culture of classical antiquity. Neoclassicism was born in Rome, largely due to the writings of Johann Joachim Winckelmann during the rediscovery of Pompeii and Herculaneum. Its popularity expanded throughout Europe as a generation of European art students finished their Grand Tour and returned from Italy to their home countries with newly rediscovered Greco-Roman ideals. The main Neoclassical movement coincided with the 18th-century Age of Enlightenment, and continued into the early 19th century, eventually competing with Romanticism. In architecture, the style endured throughout the 19th, 20th, and into the 21st century. European Neoclassicism in the visual arts began in opposition to the then-dominant Rococo style. Rococo architecture emphasizes grace, Ornament ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarinette Metal CAlt CBas
The clarinet is a single-reed musical instrument in the woodwind family, with a nearly cylindrical bore and a flared bell. Clarinets comprise a family of instruments of differing sizes and pitches. The clarinet family is the largest woodwind family, ranging from the BB♭ contrabass to the A♭ piccolo. The B soprano clarinet is the most common type, and is the instrument usually indicated by the word "clarinet". German instrument maker Johann Christoph Denner is generally credited with inventing the clarinet sometime around 1700 by adding a register key to the chalumeau, an earlier single-reed instrument. Over time, additional keywork and airtight pads were added to improve the tone and playability. Today the clarinet is a standard fixture of the orchestra and concert band and is used in classical music, military bands, klezmer, jazz, and other styles. Etymology The word "clarinet" may have entered the English language via the French (the feminine diminutive of Old Fren ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Contemporary Classical Music
Contemporary classical music is Western art music composed close to the present day. At the beginning of the 21st-century classical music, 21st century, it commonly referred to the post-1945 Modernism (music), post-tonal music after the death of Anton Webern, and included serial music, electronic music, experimental music, and minimalist music. Newer forms of music include spectral music and ''Postminimalism#Music, post-minimalism''. History Background At the beginning of the 20th century, composers of classical music were experimenting with an increasingly Consonance and dissonance, dissonant pitch language, which sometimes yielded atonality, atonal pieces. Following World War I, as a backlash against what they saw as the increasingly exaggerated gestures and formlessness of late Romanticism, certain composers adopted a Neoclassicism (music), neoclassic style, which sought to recapture the balanced forms and clearly perceptible thematic processes of earlier styles (see als ...

Instrumentation
Instrumentation is a collective term for measuring instruments, used for indicating, measuring, and recording physical quantities. It is also a field of study about the art and science about making measurement instruments, involving the related areas of metrology, automation, and control theory. The term has its origins in the art and science of Scientific instrument, scientific instrument-making. Instrumentation can refer to devices as simple as direct-reading thermometers, or as complex as multi-sensor components of industrial control systems. Instruments can be found in laboratories, refineries, factories and vehicles, as well as in everyday household use (e.g., smoke detectors and thermostats). Measurement parameters Instrumentation is used to measure many parameters (physical values), including: *Pressure, either Differential pressure transducer, differential or static pressure, static *Rate of fluid flow, Flow *Temperature measurement, Temperature *Level Measurement, L ...

Concert Pitch
Concert pitch is the pitch reference to which a group of musical instruments are tuned for a performance. Concert pitch may vary from ensemble to ensemble, and has varied widely over time. The ISO defines international standard pitch as A440, setting 440 Hz as the frequency of the A above middle C. Frequencies of other notes are defined relative to this pitch. The written pitches for transposing instruments do not match those of non-transposing instruments. For example, a written C on a B clarinet or trumpet sounds as a non-transposing instrument's B. The term "concert pitch" is used to refer to the pitch on a non-transposing instrument, to distinguish it from the transposing instrument's written note. The clarinet or trumpet's written C is thus referred to as "concert B". Modern standard concert pitch The A above middle C is often set at the international standard of 440 Hz. Historically, this A has been tuned to a variety of different pitches. History of pitch standards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boehm System
The Boehm system is a system of keywork for the flute, created by inventor and flautist Theobald Boehm between 1831 and 1847. History Immediately prior to the development of the Boehm system, flutes were most commonly made of wood, with an inverse conical bore, eight keys, and tone holes (the openings where the fingers are placed to produce specific notes) that were small in size, and thus easily covered by the fingertips. Boehm's work was inspired by an 1831 concert in London, given by soloist Charles Nicholson, who, with his father in the 1820s, had introduced a flute constructed with larger tone holes than were used in previous designs. This large-holed instrument could produce greater volume of sound than other flutes, and Boehm set out to produce his own large-holed design. In addition to large holes, Boehm provided his flute with "full venting", meaning that all keys were normally open (previously, several keys were normally closed, and opened only when the key was opera ...

Rosewood
Rosewood is any of a number of richly hued hardwoods, often brownish with darker veining, but found in other colours. It is hard, tough, strong, and dense. True rosewoods come from trees of the genus '' Dalbergia'', but other woods are often called rosewood. Rosewood takes a high polish and is used for luxury furniture-making, flooring, musical instruments, and turnery. True rosewoods Genuine rosewoods belong to the genus '' Dalbergia''. The pre-eminent rosewood appreciated in the Western world is the wood of '' Dalbergia nigra''. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name ''rosewood''. Another classic rosewood comes from '' Dalbergia latifolia'', known as (East) Indian rosewood or ''sonokeling'' (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood ('' Dalbergia maritima''), known as ''bois ...

Ebonite
Ebonite is a brand name for a material generically known as hard rubber or vulcanite, obtained via vulcanizing natural rubber for prolonged periods. Ebonite may contain from 25% to 80% sulfur and linseed oil. Its name comes from its intended use as an artificial substitute for ebony wood. The material has also been called ''vulcanite'', although that name formally refers to the mineral vulcanite. Charles Goodyear's brother, Nelson Goodyear, experimented with the chemistry of ebonite composites. In 1851, he used zinc oxide as a filler. Hugh Silver was responsible for giving it its name. Properties The sulfur percentage and the applied temperatures and duration of vulcanizing are the main variables that determine the technical properties of the hard rubber polysulfide elastomer. The occurring reaction is basically addition of sulfur at the double bonds, forming intramolecular ring structures, so a large portion of the sulfur is highly cross-linked in the form of intramolecul ...
