Artikulation (Ligeti)
''Artikulation'' is an electronic composition by György Ligeti. Composed and notated in January and February 1958, the piece was prepared and recorded on magnetic tape from February to March with the assistance of Gottfried Michael Koenig and Karlheinz Stockhausen's assistant, Cornelius Cardew, at the Studio for Electronic Music of the West German Radio (WDR) in Cologne.György Ligeti, Rainer Wehinger (1970). Artikulation: An Aural Score by Rainer Wehinger', pp. 7–8. Mainz: Schott. The piece consists of various types of sounds, "in conditions of aggregation." It "can be heard as a conversation without words". Ligeti explains in notes to the listening score (see below): The (3:53-55 long) piece, in quadraphonic sound, was premiered March 25, 1958 at WDR Cologne's 'Musik der Zeit' concert series and September 4, 1958 at Darmstadt. It was heard again March 1993 at the New England Conservatory, while for recordings it has been mixed down to stereophonic sound. Background ...

Electronic Composition
Electronic music is a genre of music that employs electronic musical instruments, digital instruments, or circuitry-based music technology in its creation. It includes both music made using electronic and electromechanical means (electroacoustic music). Pure electronic instruments depended entirely on circuitry-based sound generation, for instance using devices such as an electronic oscillator, theremin, or synthesizer. Electromechanical instruments can have mechanical parts such as strings, hammers, and electric elements including magnetic pickups, power amplifiers and loudspeakers. Such electromechanical devices include the telharmonium, Hammond organ, electric piano and the electric guitar."The stuff of electronic music is electrically produced or modified sounds. ... two basic definitions will help put some of the historical discussion in its place: purely electronic music versus electroacoustic music" ()Electroacoustic music may also use electronic effect units to change ...

Stereophonic Sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek language, Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and i ...

Impulse Generator
An impulse generator is an electrical apparatus which produces very short high-voltage or high-current surges. Such devices can be classified into two types: impulse voltage generators and impulse current generators. High impulse voltages are used to test the strength of electric power equipment against lightning and switching surges. Also, steep-front impulse voltages are sometimes used in nuclear physics experiments. High impulse currents are needed not only for tests on equipment such as lightning arresters and fuses but also for many other technical applications such as lasers, thermonuclear fusion, and plasma devices. Jedlik's tubular voltage generator In 1863 Hungarian physicist Ányos Jedlik discovered the possibility of voltage multiplication and in 1868 demonstrated it with a "tubular voltage generator", which was successfully displayed at the Vienna World Exposition in 1873. It was an early form of the impulse generators now applied in nuclear research. The jury ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Noise
In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustical engineering, telecommunications, and statistical forecasting. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal. White noise draws its name from white light, although light that appears white generally does not have a flat power spectral density over the visible band. In discrete time, white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance; a single realization of white noise is a random shock. Depending on the context, one may also require that the samples be independent and have identical probability distribution (in other words independent and iden ...

Sine Wave
A sine wave, sinusoidal wave, or just sinusoid is a curve, mathematical curve defined in terms of the ''sine'' trigonometric function, of which it is the graph of a function, graph. It is a type of continuous wave and also a Smoothness, smooth periodic function. It occurs often in mathematics, as well as in physics, engineering, signal processing and many other fields. Formulation Its most basic form as a function of time (''t'') is: y(t) = A\sin(2 \pi f t + \varphi) = A\sin(\omega t + \varphi) where: * ''A'', ''amplitude'', the peak deviation of the function from zero. * ''f'', ''frequency, ordinary frequency'', the ''Real number, number'' of oscillations (cycles) that occur each second of time. * ''ω'' = 2''f'', ''angular frequency'', the rate of change of the function argument in units of radians per second. * \varphi, ''phase (waves), phase'', specifies (in radians) where in its cycle the oscillation is at ''t'' = 0. When \varphi is non-zero, the entire waveform appears to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonetics
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds, or in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines based on the research questions involved such as how humans plan and execute movements to produce speech (articulatory phonetics), how various movements affect the properties of the resulting sound (acoustic phonetics), or how humans convert sound waves to linguistic information (auditory phonetics). Traditionally, the minimal linguistic unit of phonetics is the phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones. Phonetics deals with two aspects of human speech: production—the ways humans make sounds—and perception—the way speech is understood. The communicative modali ...

Chance Music
Aleatoric music (also aleatory music or chance music; from the Latin word ''alea'', meaning "dice") is music in which some element of the composition is left to chance, and/or some primary element of a composed work's realization is left to the determination of its performer(s). The term is most often associated with procedures in which the chance element involves a relatively limited number of possibilities. The term became known to European composers through lectures by acoustician Werner Meyer-Eppler at the Darmstadt International Summer Courses for New Music in the beginning of the 1950s. According to his definition, "a process is said to be aleatoric ... if its course is determined in general but depends on chance in detail". Through a confusion of Meyer-Eppler's German terms ''Aleatorik'' (noun) and ''aleatorisch'' (adjective), his translator created a new English word, "aleatoric" (rather than using the existing English adjective "aleatory"), which quickly became fashionab ...

AllMusic
AllMusic (previously known as All Music Guide and AMG) is an American online music database. It catalogs more than three million album entries and 30 million tracks, as well as information on musicians and bands. Initiated in 1991, the database was first made available on the Internet in 1994. AllMusic is owned by RhythmOne. History AllMusic was launched as ''All Music Guide'' by Michael Erlewine, a "compulsive archivist, noted astrologer, Buddhist scholar and musician". He became interested in using computers for his astrological work in the mid-1970s and founded a software company, Matrix, in 1977. In the early 1990s, as CDs replaced LPs as the dominant format for recorded music, Erlewine purchased what he thought was a CD of early recordings by Little Richard. After buying it he discovered it was a "flaccid latter-day rehash". Frustrated with the labeling, he researched using metadata to create a music guide. In 1990, in Big Rapids, Michigan, he founded ''All Music Guide' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Taruskin
Richard Filler Taruskin (April 2, 1945 – July 1, 2022) was an American musicologist and music critic who was among the leading and most prominent music historians of his generation. The breadth of his scrutiny into source material as well as musical analysis that combines sociological, cultural, and political perspectives, has incited much discussion, debate and controversy. He regularly wrote music criticism for newspapers including ''The New York Times''. He researched a wide variety of areas, but a central topic was the Russian music of the 18th century to present day. Other subjects he engaged with include the theory of performance, 15th-century music, 20th-century classical music, nationalism in music, the theory of modernism, and analysis. He is best known for his monumental survey of Western classical music, the six-volume ''Oxford History of Western Music''. He received several awards, including the first Noah Greenberg Award from the American Musicological Society in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Werner Meyer-Eppler
Werner Meyer-Eppler (30 April 1913 – 8 July 1960), was a Belgian-born German physicist, experimental acoustician, phoneticist and information theorist. Meyer-Eppler was born in Antwerp. He studied mathematics, physics, and chemistry, first at the University of Cologne and then in Bonn, from 1936 until 1939, when he received a doctorate in Physics. From 1942 to 1945 he was a scientific assistant at the Physics Institute of the University of Bonn. From the time of his habilitation on 16 September 1942, he was also Lecturer in Experimental Physics. After the end of the war, Meyer-Eppler turned attention increasingly to phonetics and speech synthesis. In 1947 he was recruited by Paul Menzerath to the faculty of the Phonetic Institute of the University of Bonn, where he became Scientific Assistant on 1 April 1949. During this time, Meyer-Eppler published essays on synthetic language production and presented American inventions like the Coder, the Vocoder, the Visible Speech Ma ...

Institute Of Sonology
The Institute of Sonology is an education and research center for electronic music and computer music based at the Royal Conservatoire of The Hague in the Netherlands. Background The institute was founded at Utrecht University in 1960 under the name STEM ("Studio for Electronic Music") as a successor to the former studio for electronic music at Philips Research Laboratories in Eindhoven. In 1964, Gottfried Michael Koenig became the studio's artistic director. The studio grew under Koenig's leadership, and in 1966 an annual international electronic music course was founded which exists to this day. In 1967 STEM was renamed as the "Institute of Sonology". International attention increased in 1971 with the purchase of a PDP-15 computer which was used to develop programs for algorithmic composition and digital sound synthesis. During the early years of the institute, a series of landmark programs were developed there, including Koenig's Project 1, Project 2, and SSP, Paul Berg's PILE ...
