RMI Electra Piano
Rocky Mount Instruments (RMI) was a subsidiary of the Allen Organ Company, based in Rocky Mount, North Carolina, active from 1966 to 1982. The company was formed to produce portable musical instruments, and manufactured several electronic pianos, harpsichords, and organs that used oscillators to create sound, instead of mechanical components like an electric piano. The first significant instrument produced by RMI was the Rock-Si-Chord, which emulated a harpsichord. The best-selling and most widely used instrument was the RMI Electra-piano, that was played by numerous artists in the late 1960s and early 1970s, including Steve Winwood, Genesis' Tony Banks, and Yes' Rick Wakeman. Later, the company became a pioneer of digital synthesizers, including the Keyboard Computer and RMI Harmonic Synthesizer, both were used by Jean Michel Jarre. The company struggled to compete with digital synthesizers in the early 1980s, which led to its closure. A number of sample libraries featuring RM ...

Allen Organ Company
The Allen Organ Company builds church organs, home organs, and theatre organs. Its factory is located in Macungie, Pennsylvania. The Allen International Sales Headquarters also includes the Jerome Markowitz Memorial Center, a museum. It displays many instruments that represent technological milestones in the development of the pipeless, electronicorgan. Customers of the Allen Organ Company can choose from an array of sounds. Because of hard chips and computer programming, organs can be programmed to the customer’s taste. If sounds aren’t to a customer’s satisfaction, the organ can be re-tuned or reprogrammed at home by a company representative. Many churches are switching over to computer processed organs, made or inspired by the Allen Organ Company’s models, as opposed to the traditional pipe organs. History Allen Organ Company was founded in 1937 and named after its birthplace, Allentown, Pennsylvania. The company was incorporated in 1945, after interruption by Wor ...

LC Oscillator
An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, often a sine wave or a square wave or a triangle wave. Oscillators convert direct current (DC) from a power supply to an alternating current (AC) signal. They are widely used in many electronic devices ranging from simplest clock generators to digital instruments (like calculators) and complex computers and peripherals etc. Common examples of signals generated by oscillators include signals broadcast by radio and television transmitters, clock signals that regulate computers and quartz clocks, and the sounds produced by electronic beepers and video games. Oscillators are often characterized by the frequency of their output signal: *A low-frequency oscillator (LFO) is an electronic oscillator that generates a frequency below approximately 20 Hz. This term is typically used in the field of audio synthesizers, to distinguish it from an audio frequency oscillator. *A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pictures At An Exhibition
''Pictures at an Exhibition'', french: Tableaux d'une exposition, link=no is a suite (music), suite of ten piano pieces, plus a recurring, varied Promenade theme, composed by Russian composer Modest Mussorgsky in 1874. The piece is Mussorgsky's most famous piano composition, and it has become a showpiece for virtuoso pianists. It became further widely known through various orchestrations and arrangements produced by other composers and musicians, with Maurice Ravel's 1922 adaptation for full symphony orchestra being the most recorded and performed. Composition history The composition is based on pictures by the artist, architect, and designer Viktor Hartmann. It was probably in 1868 that Mussorgsky first met Hartmann, not long after the latter's return to Russia from abroad. Both men were devoted to the cause of an intrinsically Russian art and quickly became friends. They likely met in the home of the influential critic Vladimir Stasov, who followed both of their careers with i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Modest Mussorgsky
Modest Petrovich Mussorgsky ( rus, link=no, Модест Петрович Мусоргский, Modest Petrovich Musorgsky , mɐˈdɛst pʲɪˈtrovʲɪtɕ ˈmusərkskʲɪj, Ru-Modest Petrovich Mussorgsky version.ogg; – ) was a Russian composer, one of the group known as " The Five". He was an innovator of Russian music in the Romantic period. He strove to achieve a uniquely Russian musical identity, often in deliberate defiance of the established conventions of Western music. Many of his works were inspired by Russian history, Russian folklore, and other national themes. Such works include the opera '' Boris Godunov'', the orchestral tone poem ''Night on Bald Mountain'' and the piano suite ''Pictures at an Exhibition''. For many years, Mussorgsky's works were mainly known in versions revised or completed by other composers. Many of his most important compositions have posthumously come into their own in their original forms, and some of the original scores are now also ava ...

Calliope (music)
A calliope (see below for pronunciation) is an American and Canadian musical instrument that produces sound by sending a gas, originally steam or, more recently, compressed air, through large whistles—originally locomotive whistles. A calliope is typically very loud. Even some small calliopes are audible for miles. There is no way to vary tone or loudness. Musically, the only expression possible is the pitch, rhythm, and duration of the notes. The steam calliope is also known as a steam organ (''orgue à vapeur'' in Quebec) or steam piano (''piano à vapeur'' in Quebec). The air-driven calliope is sometimes called a calliaphone, the name given to it by Norman Baker, but the "Calliaphone" name is registered by the Miner Company for instruments produced under the Tangley name. In the age of steam, the steam calliope was particularly used on riverboats and in circuses. In both cases, a steam supply was readily available for other purposes. Riverboats supplied steam from thei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
C♯ (musical Note)
C (C-sharp) is a musical note lying a chromatic semitone above C and a diatonic semitone below D; it is the second semitone of the solfège. C-sharp is thus enharmonic to D. It is the second semitone in the French solfège and is known there as ''do dièse''. In some European notations, it is known as Cis. In equal temperament it is also enharmonic with B (B-double sharp/Hisis). When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of C4 (the C above middle C) is about 277.183 Hz. See pitch (music) for a discussion of historical variations in frequency. Designation by octave Scales Common scales beginning on C * C major: C D E F G A B C * C natural minor: C D E F G A B C * C harmonic minor: C D E F G A B C * C melodic minor ascending: C D E F G A B C * C melodic minor descending: C B A G F E D C Diatonic scales * C Ionian: C D E F G A B C * C Dorian: C D E F G A B C * C Phrygian: C D E F G A B C * C Lydian: C D E F G A B C ...

C (musical Note)
C or Do is the first note and semitone 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 by adherents 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 ...

Mandolin
A mandolin ( it, mandolino ; literally "small mandola") is a stringed musical instrument in the lute family and is generally plucked with a pick. It most commonly has four courses of doubled strings tuned in unison, thus giving a total of 8 strings, although five (10 strings) and six (12 strings) course versions also exist. There are of course different types of strings that can be used, metal strings are the main ones since they are the cheapest and easiest to make. The courses are typically tuned in an interval of perfect fifths, with the same tuning as a violin (G3, D4, A4, E5). Also, like the violin, it is the soprano member of a family that includes the mandola, octave mandolin, mandocello and mandobass. There are many styles of mandolin, but the three most common types are the ''Neapolitan'' or ''round-backed'' mandolin, the ''archtop'' mandolin and the ''flat-backed'' mandolin. The round-backed version has a deep bottom, constructed of strips of wood, glued togethe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banjo
The banjo is a stringed instrument with a thin membrane stretched over a frame or cavity to form a resonator. The membrane is typically circular, and usually made of plastic, or occasionally animal skin. Early forms of the instrument were fashioned by African Americans in the United States. The banjo is frequently associated with folk, bluegrass and country music, and has also been used in some rock, pop and hip-hop. Several rock bands, such as the Eagles, Led Zeppelin, and the Grateful Dead, have used the five-string banjo in some of their songs. Historically, the banjo occupied a central place in Black American traditional music and the folk culture of rural whites before entering the mainstream via the minstrel shows of the 19th century. Along with the fiddle, the banjo is a mainstay of American styles of music, such as bluegrass and old-time music. It is also very frequently used in Dixieland jazz, as well as in Caribbean genres like biguine, calypso and mento. Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octave
In music, an octave ( la, octavus: eighth) or perfect octave (sometimes called the diapason) is the interval between one musical pitch and another with double its frequency. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music," the use of which is "common in most musical systems." The interval between the first and second harmonics of the harmonic series is an octave. In Western music notation, notes separated by an octave (or multiple octaves) have the same name and are of the same pitch class. To emphasize that it is one of the perfect intervals (including unison, perfect fourth, and perfect fifth), the octave is designated P8. Other interval qualities are also possible, though rare. The octave above or below an indicated note is sometimes abbreviated ''8a'' or ''8va'' ( it, all'ottava), ''8va bassa'' ( it, all'ottava bassa, sometimes also ''8vb''), or simply ''8'' for the octave in the direction indicated by placing ...
