Mikrophonie
''Mikrophonie'' is the title given by Karlheinz Stockhausen to two of his compositions, written in 1964 and 1965, in which "normally inaudible vibrations ... are made audible by an active process of sound detection (comparable to the auscultation of a body by a physician); the microphone is used actively as a musical instrument, in contrast to its former passive function of reproducing sounds as faithfully as possible". Together with Stockhausen's immediately preceding work ''Mixtur'', for five orchestra groups, four sine-wave generators, four ring modulators, they form a triptych of live-electronic works, where electronic transformations are accomplished during the performance (as opposed to studio-produced electronic music on tape). Similar to a group of three of the composer's works from the previous decade, ''Gruppen'', ''Zeitmaße'', and ''Gesang der Jünglinge'', there is one work each for orchestral, chamber, and vocal forces.

Karlheinz Stockhausen
Karlheinz Stockhausen (; 22 August 1928 – 5 December 2007) was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. He is known for his groundbreaking work in electronic music, for introducing controlled chance ( aleatory techniques) into serial composition, and for musical spatialization. He was educated at the Hochschule für Musik Köln and the University of Cologne, later studying with Olivier Messiaen in Paris and with Werner Meyer-Eppler at the University of Bonn. One of the leading figures of the Darmstadt School, his compositions and theories were and remain widely influential, not only on composers of art music, but also on jazz and popular music. His works, composed over a period of nearly sixty years, eschew traditional forms. In addition to electronic music—both with and without live performers—they range from miniatures for musical boxes through works for s ...

Live Electronic Music
Live electronic music (also known as live electronics) is a form of music that can include traditional electronic sound-generating devices, modified electric musical instruments, hacked sound generating technologies, and computers. Initially the practice developed in reaction to sound-based composition for fixed media such as musique concrète, electronic music and early computer music. Musical improvisation often plays a large role in the performance of this music. The timbres of various sounds may be transformed extensively using devices such as amplifiers, filters, ring modulators and other forms of circuitry. Real-time generation and manipulation of audio using live coding is now commonplace. History 1800s–1940s Early electronic instruments Early electronic instruments intended for live performance, such as Thaddeus Cahill's Telharmonium (1897) and instruments developed between the two world wars, such as the Theremin (1919), Spharophon (1924), ondes Martenot (1928), and t ...

Moment Form
In music, moment form is defined as "a mosaic of moments", and, in turn, a moment is defined as a "self-contained (quasi-)independent section, set off from other sections by discontinuities". History and definition The concept of moment form, and the specific term, originated with the composition ''Kontakte'' (1958–60) by Karlheinz Stockhausen. A "moment", in Stockhausen's terminology, is any "formal unit in a particular composition that is recognizable by a personal and unmistakable character." It can be either an indivisible ''gestalt'', a structure with clear components, or a mixture of the two; and it can be static, or dynamic, or a combination of the two. "Depending on their characteristics, they can be as long or as short as you like". "Moment ''forming''", on the other hand, is a compositional approach in which a narrative overall line is deliberately avoided. The component moments in such a form are related by a nonlinear principle of proportions. If this system of propor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Music
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 ...

Aloys And Alfons Kontarsky
Aloys (14 May 1931 – 22 August 2017) and Alfons (9 October 1932 – 5 May 2010) Kontarsky were German duo-pianist brothers who were associated with a number of important world premieres of contemporary works. They had an international reputation for performing modern music for two pianists, although they also performed the standard repertoire and they sometimes played separately. They were occasionally joined by their younger brother Bernhard in performances of pieces for three pianos. After suffering a stroke in 1983, Aloys retired from performing. Biography The Kontarsky brothers were both born in Iserlohn. Aloys received early tuition from Franz Hanemann. He later studied at Cologne and Hamburg with Else Schmitz-Gohr, and with Eduard Erdmann in Hamburg. Their first public concert was in 1949, in which they played Stravinsky's Concerto for Two Pianos. In 1955 they formed their piano duo "Klavierduo Kontarsky" and performed regularly from 1959 until Aloys became paralyzed ...

Ring Modulation
In electronics, ring modulation is a signal processing function, an implementation of frequency mixing, in which two signals are combined to yield an output signal. One signal, called the carrier, is typically a sine wave or another simple waveform; the other signal is typically more complicated and is called the input or the modulator signal. A ring modulator is an electronic device for ring modulation. A ring modulator may be used in music synthesizers and as an effects unit. The name derives from the fact that the analog circuit of diodes originally used to implement this technique takes the shape of a ring: a diode ring. The circuit is similar to a bridge rectifier, except that instead of the diodes facing left or right, they face clockwise or counterclockwise. Ring modulation is quite similar to amplitude modulation, with the difference that in the latter the modulator is shifted to be positive before being multiplied with the carrier, while in the former the unshifted ...

Process Music
Process music is music that arises from a process. It may make that process audible to the listener, or the process may be concealed. Primarily begun in the 1960s, diverse composers have employed divergent methods and styles of process. "A 'musical process' as Christensen defines it is a highly complex dynamic phenomenon involving audible structures that evolve in the course of the musical performance ... 2nd order audible developments, i.e., audible developments within audible developments". These processes may involve specific systems of choosing and arranging notes through pitch and time, often involving a long term change with a limited amount of musical material, or transformations of musical events that are already relatively complex in themselves. Steve Reich defines process music not as, "the process of composition but rather pieces of music that are, literally, processes. The distinctive thing about musical processes is that they determine all the note-to-note (sound-to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gong
A gongFrom Indonesian and ms, gong; jv, ꦒꦺꦴꦁ ; zh, c=鑼, p=luó; ja, , dora; km, គង ; th, ฆ้อง ; vi, cồng chiêng; as, কাঁহ is a percussion instrument originating in East Asia and Southeast Asia. Gongs are a flat, circular metal disc that is typically struck with a mallet. They can be small or large in size, and tuned or can require tuning. The earliest mention of gongs can be found in sixth century Chinese records, which mentioned the instrument to have come from a country between Tibet and Burma. The term ''gong'' ( jv, ꦒꦺꦴꦁ) originated in the Indonesian island of Java. Scientific and archaeological research has established that Burma, China, Java and Annam were the four main gong manufacturing centres of the ancient world. The gong found its way into the Western World in the 18th century, when it was also used in the percussion section of a Western-style symphony orchestra.

Fibonacci Series
In mathematics, the Fibonacci numbers, commonly denoted , form a sequence, the Fibonacci sequence, in which each number is the sum of the two preceding ones. The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the first few values in the sequence are: :0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144. The Fibonacci numbers were first described in Indian mathematics, as early as 200 BC in work by Pingala on enumerating possible patterns of Sanskrit poetry formed from syllables of two lengths. They are named after the Italian mathematician Leonardo of Pisa, later known as Fibonacci, who introduced the sequence to Western European mathematics in his 1202 book ''Liber Abaci''. Fibonacci numbers appear unexpectedly often in mathematics, so much so that there is an entire journal dedicated to their study, the ''Fibonacci Quarterly''. Applications of Fibonacci numbers include co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hammond Organ
The Hammond organ is an electric organ invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Multiple models have been produced, most of which use sliding drawbars to vary sounds. Until 1975, Hammond organs generated sound by creating an electric current from rotating a metal tonewheel near an electromagnetic pickup, and then strengthening the signal with an amplifier to drive a speaker cabinet. The organ is commonly used with the Leslie speaker. Around two million Hammond organs have been manufactured. The organ was originally marketed by the Hammond Organ Company to churches as a lower-cost alternative to the wind-driven pipe organ, or instead of a piano. It quickly became popular with professional jazz musicians in organ trios—small groups centered on the Hammond organ. Jazz club owners found that organ trios were cheaper than hiring a big band. Jimmy Smith's use of the Hammond B-3, with its additional harmonic percussion feature, inspired a g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shotgun Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helmut Heißenbüttel
Helmut Heißenbüttel (21 June 1921 – 19 September 1996) was a German novelist and poet. Among Heißenbüttel's works are ''Das Textbuch'' (''The Textbook'') and ''Marlowe's Ende'' (''Marlowe's End''). He received the important Georg Büchner Prize in 1969. His other awards include the Bundesverdienstkreuz Erster Klasse (1979) and the Austrian State Prize for European Literature (1990). Heißenbüttel was born in Wilhelmshaven, Germany. During the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposin ..., he was badly wounded at the Eastern Front so that his left arm had to be amputated. He married Ida Warnholtz in 1954 (one son, three daughters). Heißenbüttel died of pneumonia at a hospital in Glückstadt. His dying words were "wie ein Schokoladen-Milchshake nur knac ...
