Mixtur
''Mixtur'', for orchestra, 4 sine-wave generators, and 4 ring modulators, is an orchestral composition by the German composer Karlheinz Stockhausen, written in 1964, and is Nr. 16 in his catalogue of works. It exists in three versions: the original version for full orchestra, a reduced scoring made in 1967 (Nr. 16), and a re-notated version of the reduced scoring, made in 2003 and titled ''Mixtur 2003'', Nr. 16. History ''Mixtur'' is one of the earliest compositions for orchestra with live electronics, and is amongst the first compositions using live-electronic techniques generally. The original version for large orchestra was premiered on 9 November 1965 at the Norddeutscher Rundfunk, Hamburg. The version for reduced orchestra was premiered in the large broadcasting hall of the Hessischer Rundfunk, Frankfurt am Main, as part of the Darmstädter Ferienkurse on 23 August 1967 by the Ensemble Hudba Dneska conducted by Ladislav Kupkovič, to whom this version is d ...

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 Musique concrète (; ): "[A] problem for any translator of an academic work in French is that the language is relatively abstract and theoretical compared to English; one might even say that the mode of thinking itself tends to be more schematic ..., 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, Electronic filter, filters, ring modulation, ring modulators and other forms of electronic circuit, circuitry. Real-time computing, Real-time generation and manipulation of audio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (Stockhausen), 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 ''wikt:gestalt, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, having been called the "father of electronic music", for introducing controlled chance ( aleatory techniques) into serial composition, and for musical spatialization. Stockhausen 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. As 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 musicboth with and without live performersthe ...

Ladislav Kupkovič
Ladislav Kupkovič (17 March 1936 – 15 June 2016) was a Slovak composer and conductor . Life Kupkovič was born in Bratislava, and studied violin and conducting there, first at the conservatory, then at the Academy of Performing Arts. He played violin in the Slovak Philharmonic Orchestra from 1960 to 1965, and then began to write music for television and film to make a living. At the same time, he was writing more experimental music for concerts. In 1969 he won a music scholarship to West Berlin, and emigrated there the following year. In 1971, he conducted the premiere of Karlheinz Stockhausen's '' Mixtur'' in Cologne, a piece dedicated to Kupkovič himself. In the same year, he began to teach music theory at the Hochschule für Musik und Theater Hannover, and lived in Haste near Hannover until his death. During the 1970s he was associated with the Cologne School . Wandelkonzerte Kupkovič has probably become best known for his experiments with the concert form in the 19 ...

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. The ring modulator takes its name from the original implementation in which the analog circuit of diodes takes the shape of a ring, a diode ring. The circuit is similar to a bridge rectifier, except that all four diodes are polarized in the same direction. Ring modulation is 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 modulator signal is multiplied with the carrier. This has the effect that ring modulation of two sine waves having frequencies of 1,500 Hz and 400 Hz produce an output signal th ...

Brass Instrument
A brass instrument is a musical instrument that produces sound by Sympathetic resonance, sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. The term ''labrosone'', from Latin elements meaning "lip" and "sound", is also used for the group, since instruments employing this "lip reed" method of sound production can be made from other materials like wood or animal horn, particularly early or traditional instruments such as the cornett, alphorn or shofar. There are several factors involved in producing different Pitch of brass instruments, pitches on a brass instrument. Slide (wind instrument), Slides, Brass instrument valve, valves, Crook (music), crooks (though they are rarely used today), or Key (instrument), keys are used to change vibratory length of tubing, thus changing the available harmonic series (music), harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produ ...

David C
David (; , "beloved one") was a king of ancient Israel and Judah and the third king of the United Monarchy, according to the Hebrew Bible and Old Testament. The Tel Dan stele, an Aramaic-inscribed stone erected by a king of Aram-Damascus in the late 9th/early 8th centuries BCE to commemorate a victory over two enemy kings, contains the phrase (), which is translated as " House of David" by most scholars. The Mesha Stele, erected by King Mesha of Moab in the 9th century BCE, may also refer to the "House of David", although this is disputed. According to Jewish works such as the '' Seder Olam Rabbah'', '' Seder Olam Zutta'', and '' Sefer ha-Qabbalah'' (all written over a thousand years later), David ascended the throne as the king of Judah in 885 BCE. Apart from this, all that is known of David comes from biblical literature, the historicity of which has been extensively challenged,Writing and Rewriting the Story of Solomon in Ancient Israel; by Isaac Kalimi; page 3 ...

Rolf Gehlhaar
Rolf Rainer Gehlhaar (30 December 1943 – 7 July 2019) was an American composer, Professor in Experimental Music at Coventry University and researcher in assistive technology for music. Life Born in Breslau, Gehlhaar was the son of a German rocket scientist, who emigrated to the United States in 1953 to work at a rocket-development research centre in New Mexico. Although he took an interest in music from the age of eight or younger, in the post-war years the family could not afford for him to learn an instrument, and so Rolf only began to play the piano at the age of fifteen, and at about the same time began to compose for fun. He took American citizenship in 1958 and studied at Yale University and the University of California, Berkeley. Initially, he had studied medicine, but soon changed his major to philosophy and the philosophy of science; then at Yale he attended a course in composition, which was an arousing experience. He moved to Cologne, Germany, in 1967 to become assista ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannes Fritsch
Johannes Georg Fritsch (27 July 1941 – 29 April 2010) was a German composer. At the age of seven, Fritsch found a violin in the attic of his uncle's house in Bensheim-Auerbach, Germany, and began lessons with a village music teacher named Knapp. When he was ten, his family moved to Cologne, and he began studying with the principal violist in the Gürzenich Orchestra. He studied music, sociology, and philosophy from 1961 to 1965 at the University and the Staatliche Musikhochschule in Cologne with, amongst others, Bernd Alois Zimmermann and Gottfried Michael Koenig. In the following years he applied himself to the most varied musical activities. Amongst other things he played viola in the Stockhausen-Ensemble from 1964 to 1970, and took part in the German exhibition at Expo '70, the World's Fair in Osaka in 1970. Although he had begun to compose at the age of 17, Fritsch regards as his first real composition the ''Duett für Bratsche'' (Duet for Viola), for viola and tape, ...

Middle C
C or Do is the first note of the C major scale, the third note of the A minor scale (the relative minor of C major), and the fourth note (G, A, B, C) of the Guidonian hand, commonly pitched around 261.63 Hz. The actual frequency has depended on historical pitch standards, and for transposing instruments a distinction is made between written and sounding or concert pitch. It has enharmonic equivalents of B and D. In English the term ''Do'' is used interchangeably with C only in the context of fixed Do solfège; in the movable Do system Do refers to the tonic of the prevailing key. Frequency Historically, concert pitch has varied. For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies). Scientific pitch was originally proposed in 1713 by French physicist Joseph Sauveur and based on the numerically convenient frequency of 256 ...
