Spharophon
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 Donau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Musical Instrument
An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener. An electronic instrument might include a user interface for controlling its sound, often by adjusting the pitch, frequency, or duration of each note. A common user interface is the musical keyboard, which functions similarly to the keyboard on an acoustic piano, except that with an electronic keyboard, the keyboard itself does not make any sound. An electronic keyboard sends a signal to a synth module, computer or other electronic or digital sound generator, which then creates a sound. However, it is increasingly common to separate user interface and sound-generating functions into a music controller (input device) and a music synthes ...

Heterodyning
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 app ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ondes Martenot
The ondes Martenot ( ; , "Martenot waves") or ondes musicales ("musical waves") is an early electronic musical instrument. It is played with a keyboard or by moving a ring along a wire, creating "wavering" sounds similar to a theremin. A player of the ondes Martenot is called an ondist. The ondes Martenot was invented in 1928 by the French inventor Maurice Martenot. Martenot was inspired by the accidental overlaps of tones between military radio oscillators, and wanted to create an instrument with the expressiveness of the cello. The ondes Martenot is used in more than 100 orchestral compositions. The French composer Olivier Messiaen used it in pieces such as his 1949 symphony '' Turangalîla-Symphonie,'' and his sister-in-law Jeanne Loriod was a celebrated player of the instrument. It appears in numerous film and television soundtracks, particularly science fiction and horror films. Jonny Greenwood of the English rock band Radiohead is credited with bringing the ondes to a ...

Dartmouth College
Dartmouth College (; ) is a private research university in Hanover, New Hampshire. Established in 1769 by Eleazar Wheelock, it is one of the nine colonial colleges chartered before the American Revolution. Although founded to educate Native Americans in Christian theology and the English way of life, the university primarily trained Congregationalist ministers during its early history before it gradually secularized, emerging at the turn of the 20th century from relative obscurity into national prominence. It is a member of the Ivy League. Following a liberal arts curriculum, Dartmouth provides undergraduate instruction in 40 academic departments and interdisciplinary programs, including 60 majors in the humanities, social sciences, natural sciences, and engineering, and enables students to design specialized concentrations or engage in dual degree programs. In addition to the undergraduate faculty of arts and sciences, Dartmouth has four professional and graduate sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
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 opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Donaueschingen
Donaueschingen (; Low Alemannic: ''Eschinge'') is a German town in the Black Forest in the southwest of the federal state of Baden-Württemberg in the Schwarzwald-Baar '' Kreis''. It stands near the confluence of the two sources of the river Danube (in german: Donau). Donaueschingen stands in a basin within low mountainous terrain.

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 ...
