Jörg Mager
Jörg Georg Adam Mager (6 November 1880 - 5 April 1939) was a German musician and inventor, who was a pioneer of early electronic music. Mager was born in Eichstätt in Bavaria, in 1880. An idealist by nature, he worked as a schoolteacher and organist to fund his research into electronic instruments. In 1911, after hearing an organ that had become slightly detuned due to temperature variations, Mager began researching quarter tones, and built a harmonium based on quarter-tonal divisions. This became the basis for many of his later instruments. In the 1920s, Mager developed the Electrophon (later renamed to the Sphärophon), a keyboard instrument that produced sound using heterodyning. Its premiere at the 1926 Donaueschingen Festival was well received by the attendees, including Paul Hindemith and Alois Hába. In the late 1920s Mager received a government grant, and used this money to found a laboratory near Darmstadt Darmstadt () is a city in the States of Germany, state ...

Aschaffenburg
Aschaffenburg (; South Franconian: ''Aschebersch'') is a town in northwest Bavaria, Germany. The town of Aschaffenburg is not part of the district of Aschaffenburg, but is its administrative seat. Aschaffenburg belonged to the Archbishopric of Mainz for more than 800 years. The town is located at the westernmost border of Lower Franconia and separated from the central and eastern part of the ''Regierungsbezirk'' (administrative region) by the Spessart hills, whereas it opens towards the Rhine-Main plain in the west and north-west. Therefore, the inhabitants speak neither Bavarian nor East Franconian but rather a local version of Rhine Franconian. Geography Location The town is located on both sides of the Main in north-west Bavaria, bordering to Hesse. On a federal scale it is part of central Germany, just southeast of Frankfurt am Main. In the western part of the municipality, the smaller Aschaff flows into the Main. The region is also known as ''Bayerischer Untermain ...

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 ...

Bavaria
Bavaria ( ; ), officially the Free State of Bavaria (german: Freistaat Bayern, link=no ), is a state in the south-east of Germany. With an area of , Bavaria is the largest German state by land area, comprising roughly a fifth of the total land area of Germany. With over 13 million inhabitants, it is second in population only to North Rhine-Westphalia, but due to its large size its population density is below the German average. Bavaria's main cities are Munich (its capital and largest city and also the third largest city in Germany), Nuremberg, and Augsburg. The history of Bavaria includes its earliest settlement by Iron Age Celtic tribes, followed by the conquests of the Roman Empire in the 1st century BC, when the territory was incorporated into the provinces of Raetia and Noricum. It became the Duchy of Bavaria (a stem duchy) in the 6th century AD following the collapse of the Western Roman Empire. It was later incorporated into the Holy Roman Empire, became an ind ...

Quarter Tone
A quarter tone is a pitch halfway between the usual notes of a chromatic scale or an interval about half as wide (aurally, or logarithmically) as a semitone, which itself is half a whole tone. Quarter tones divide the octave by 50 cents each, and have 24 different pitches. Quarter tone has its roots in the music of the Middle East and more specifically in Persian traditional music. However, the first evidenced proposal of quarter tones, or the quarter-tone scale (24 equal temperament), was made by 19th-century music theorists Heinrich Richter in 1823Julian Rushton, "Quarter-Tone", ''The New Grove Dictionary of Music and Musicians'', second edition, edited by Stanley Sadie and John Tyrrell (London: Macmillan, 2001). and Mikhail Mishaqa about 1840. Composers who have written music using this scale include: Pierre Boulez, Julián Carrillo, Mildred Couper, George Enescu, Alberto Ginastera, Gérard Grisey, Alois Hába, Ljubica Marić, Charles Ives, Tristan Murail, Krzysztof Pendere ...

Harmonium
The pump organ is a type of free-reed organ that generates sound as air flows past a vibrating piece of thin metal in a frame. The piece of metal is called a reed. Specific types of pump organ include the reed organ, harmonium, and melodeon. The idea for the free reed was imported from China through Russia after 1750, and the first Western free-reed instrument was made in 1780 in Denmark. More portable than pipe organs, free-reed organs were widely used in smaller churches and in private homes in the 19th century, but their volume and tonal range were limited. They generally had one or sometimes two manuals, with pedal-boards being rare. The finer pump organs had a wider range of tones, and the cabinets of those intended for churches and affluent homes were often excellent pieces of furniture. Several million free-reed organs and melodeons were made in the US and Canada between the 1850s and the 1920s, some of which were exported. The Cable Company, Estey Organ, and Mason & ...

Sphärophon
The Sphärophon or a Spherophone is an electrical musical instrument that was first made as the "Electrophon" around 1921 by Jörg Mager, later modified, renamed and exhibited in 1926. Two variants of the Sphärophon Mager invented two different variants of the Sphärophon. The first version was similar to a Theremin, but Mager's design had the capability to change the timbre of the sound that was produced as well as utilize discrete pitches. His second prototype was keyboard-based but used a radio frequency oscillator as well. This instrument was capable of producing quarter tones of an octave. In many of his instruments, including the Sphärophon, Mager experimented with the drivers in the loudspeakers to achieve different sounds as well. Public demonstration Mager premiered his special new instrument at the Donaueschingen Festival, Germany in 1926. The festival had been started in 1921 to promote new types of music and still continues to this day in the town of Donaueschi ...

Heterodyne
A heterodyne is a signal frequency that is created by combining or mixing two other frequencies using a signal processing technique called ''heterodyning'', which was invented by Canadian inventor-engineer Reginald Fessenden. Heterodyning is used to shift signals from one frequency range into another, and is also involved in the processes of modulation and demodulation. The two input frequencies are combined in a nonlinear signal-processing device such as a vacuum tube, transistor, or diode, usually called a '' mixer''. In the most common application, two signals at frequencies and are mixed, creating two new signals, one at the sum of the two frequencies , and the other at the difference between the two frequencies . The new signal frequencies are called ''heterodynes''. Typically, only one of the heterodynes is required and the other signal is filtered out of the output of the mixer. Heterodyne frequencies are related to the phenomenon of "beats" in acoustics. A major a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donaueschingen Festival
The Donaueschingen Festival (german: Donaueschinger Musiktage, links=no) is a festival for new music that takes place every October in the small town of Donaueschingen in south-western Germany. Founded in 1921, it is considered the oldest festival for contemporary classical music in the world, and among the best-known and most prestigious. History In 1913, the ''Donaueschingen Society of Friends of Music'' was founded under the auspices of the House of Fürstenberg. The idea soon arose to establish a small festival for presenting young and promising artists. A committee of distinguished musicians, among them Ferruccio Busoni, Joseph Haas, Hans Pfitzner, Arthur Nikisch and Richard Strauss, met in 1921 to discuss possible formats for the event. The first concert was presented just a few months later. On 31 July 1921 the ''Donaueschingen Chamber Music Performances for the advancement of contemporary music'' (''Donaueschinger Kammermusikaufführungen zur Förderung zeitgenössischer ...

Paul Hindemith
Paul Hindemith (; 16 November 189528 December 1963) was a German composer, music theorist, teacher, violist and conductor. He founded the Amar Quartet in 1921, touring extensively in Europe. As a composer, he became a major advocate of the ''Neue Sachlichkeit'' (new objectivity) style of music in the 1920s, with compositions such as '' Kammermusik'', including works with viola and viola d'amore as solo instruments in a neo-Bachian spirit. Other notable compositions include his song cycle ''Das Marienleben'' (1923), ''Der Schwanendreher'' for viola and orchestra (1935), the opera ''Mathis der Maler'' (1938), the '' Symphonic Metamorphosis of Themes by Carl Maria von Weber'' (1943), and the oratorio ''When Lilacs Last in the Dooryard Bloom'd'', a requiem based on Walt Whitman's poem (1946). Life and career Hindemith was born in Hanau, near Frankfurt, the eldest child of the painter and decorator Robert Hindemith from Lower Silesia and his wife Marie Hindemith, née Warnecke. H ...

Alois Hába
Alois Hába (21 June 1893 – 18 November 1973) was a Czech composer, music theorist and teacher. He belongs to the important discoverers in modern classical music, and major composers of microtonal music, especially using the quarter-tone scale, though he used others such as sixth-tones (e.g., in the 5th, 10th and 11th String Quartets), fifth-tones (Sixteenth String Quartet), and twelfth-tones. From the other microtonal conceptions, he discussed a "three-quarter tone" system (see three-quarter tone flat and the neutral second) in his theoretical works but he used scales in this tuning in sections of some of his compositions. In his prolific career, Hába composed three operas, an enormous collection of chamber music including 16 string quartets, piano, organ and choral pieces, some orchestral works and songs. He also had special keyboard and woodwind instruments constructed that were capable of playing quarter-tone scales. Life Alois Hába was born in the small town of V ...
