Moog Apollo
The Polymoog is a hybrid polyphonic analog synthesizer that was manufactured by Moog Music from 1975 to 1980. The Polymoog was based on divide-down oscillator technology similar to electronic organs and string synthesizers of the time. History The name Polymoog can refer either to the original Polymoog Synthesizer (model 203a) released in 1975, or the largely preset Polymoog Keyboard (model 280a) released in 1978. The Polymoog has a 71-note weighted Pratt & Read touch-sensitive keyboard divided into three sections with a volume slider for each. It also has a three-band resonant graphic equalizer section, which can be changed to a low/bandpass/high-pass filter. The Moog-designed 24 dB/octave filter section allows modulation modulated from its own envelopes, low frequency oscillation and sample and hold circuit. Ranks and waveforms of all notes are also adjustable combining waveforms, octaves, tunings, and their own independent LFO rates and amounts. The user can adjus ...

Moog Music
Moog Music Inc. () is an American synthesizer company based in Asheville, North Carolina. It was founded in 1953 as R. A. Moog Co. by Robert Moog and his father and was renamed Moog Music in 1972. Its early instruments included the Moog synthesizer (the first commercial synthesizer), followed by the Minimoog in 1970, two of the most influential electronic instruments of all time. In 1971, following a Recession of 1969–70, recession, Robert Moog sold Moog Music to Norlin Musical Instruments, where he remained employed as a designer until 1977. In 1978, he founded a new company, Big Briar. Moog Music filed for bankruptcy in 1987 and the Moog Music trademark was returned to Robert Moog in 2002, when Big Briar resumed operations under the name Moog Music. Moog Music also manages Moogfest, a pioneering electronic music and music technology festival in Durham, NC. History 1953–1967: R. A. Moog Co. Robert Moog founded R. A.

Musical Keyboard
A musical keyboard is the set of adjacent depressible levers or keys on a musical instrument. Keyboards typically contain keys for playing the twelve notes of the Western musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeats at the interval of an octave. Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine ( acoustic and electric piano, clavichord), plucking a string ( harpsichord), causing air to flow through a pipe organ, striking a bell (carillon), or, on electric and electronic keyboards, completing a circuit (Hammond organ, digital piano, synthesizer). Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the ''piano keyboard''. Description The twelve notes of the Western musical scale are laid out with the lowest note on the left. The longer keys (for the seven "natural" notes of the C major scale: C, D, E ...

Brass Instrument
A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. Brass instruments are also called labrosones or labrophones, from Latin and Greek elements meaning 'lip' and 'sound'. There are several factors involved in producing different pitches on a brass instrument. Slides, valves, crooks (though they are rarely used today), or keys are used to change vibratory length of tubing, thus changing the available harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produced from the available series. The view of most scholars (see organology) is that the term "brass instrument" should be defined by the way the sound is made, as above, and not by whether the instrument is actually made of brass. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent and the didgeridoo, while some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vibraphone
The vibraphone is a percussion instrument in the metallophone family. It consists of tuned metal bars and is typically played by using mallets to strike the bars. A person who plays the vibraphone is called a ''vibraphonist,'' ''vibraharpist,'' or ''vibist''. The vibraphone resembles the steel marimba, which it superseded. One of the main differences between the vibraphone and other keyboard percussion instruments is that each bar suspends over a resonator tube containing a flat metal disc. These discs are attached together by a common axle and spin when the motor is turned on. This causes the instrument to produce its namesake tremolo or vibrato effect. The vibraphone also has a sustain pedal similar to a piano. When the pedal is up, the bars produce a muted sound; when the pedal is down, the bars sustain for several seconds or until again muted with the pedal. The vibraphone is commonly used in jazz music, in which it often plays a featured role, and was a defining element ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clavichord
The clavichord is a stringed rectangular keyboard instrument that was used largely in the Late Middle Ages, through the Renaissance, Baroque and Classical eras. Historically, it was mostly used as a practice instrument and as an aid to composition, not being loud enough for larger performances. The clavichord produces sound by striking brass or iron strings with small metal blades called tangents. Vibrations are transmitted through the bridge(s) to the soundboard. Etymology The name is derived from the Latin word ''clavis'', meaning "key" (associated with more common ''clavus'', meaning "nail, rod, etc.") and ''chorda'' (from Greek χορδή) meaning "string, especially of a musical instrument". An analogous name is used in other European languages (It. ''clavicordio'', ''clavicordo''; Fr. ''clavicorde''; Germ. ''Klavichord''; Lat. ''clavicordium''; Port. ''clavicórdio''; Sp. ''clavicordio''). Many languages also have another name derived from Latin ''manus'', meaning "hand" ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Funk
Funk is a music genre that originated in African American communities in the mid-1960s when musicians created a rhythmic, danceable new form of music through a mixture of various music genres that were popular among African Americans in the mid-20th century. It de-emphasizes melody and chord progressions and focuses on a strong rhythmic groove of a bassline played by an electric bassist and a drum part played by a percussionist, often at slower tempos than other popular music. Funk typically consists of a complex percussive groove with rhythm instruments playing interlocking grooves that create a "hypnotic" and "danceable" feel. Funk uses the same richly colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths and thirteenths. Funk originated in the mid-1960s, with James Brown's development of a signature groove that emphasized the downbeat—with a heavy emphasis on the first bea ...

Harpsichord
A harpsichord ( it, clavicembalo; french: clavecin; german: Cembalo; es, clavecín; pt, cravo; nl, klavecimbel; pl, klawesyn) is a musical instrument played by means of a keyboard. This activates a row of levers that turn a trigger mechanism that plucks one or more strings with a small plectrum made from quill or plastic. The strings are under tension on a soundboard, which is mounted in a wooden case; the soundboard amplifies the vibrations from the strings so that the listeners can hear it. Like a pipe organ, a harpsichord may have more than one keyboard manual, and even a pedal board. Harpsichords may also have stop buttons which add or remove additional octaves. Some harpsichords may have a buff stop, which brings a strip of buff leather or other material in contact with the strings, muting their sound to simulate the sound of a plucked lute. The term denotes the whole family of similar plucked-keyboard instruments, including the smaller virginals, muselar, and spinet. ...

Overview Overview includes: * Pipe organs, which use air moving through pipes to produce sounds. Since the 16th century, pipe organs have used various materials for pipes, which can vary widely in timbre and volume. Increasingly hybrid organs are appearing in which pipes are augmented with electric additions. Great economies of space and cost are possible especially when the lowest (and largest) of the pipes can be replaced; * Non-piped organs, which include: ** pump organs, also known as reed organs or harmoniums, which ...

Piano
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description The word "piano" is a shortened form of ''pianoforte'', the Italian term for the early 1700s versions of the instrument, which in turn derives from ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) and ''fortepiano''. The Italian musical terms ''piano'' and ''forte'' indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the grea ...

String Instrument
String instruments, stringed instruments, or chordophones are musical instruments that produce sound from vibrating strings when a performer plays or sounds the strings in some manner. Musicians play some string instruments by plucking the strings with their fingers or a plectrum—and others by hitting the strings with a light wooden hammer or by rubbing the strings with a bow. In some keyboard instruments, such as the harpsichord, the musician presses a key that plucks the string. Other musical instruments generate sound by striking the string. With bowed instruments, the player pulls a rosined horsehair bow across the strings, causing them to vibrate. With a hurdy-gurdy, the musician cranks a wheel whose rosined edge touches the strings. Bowed instruments include the string section instruments of the orchestra in Western classical music (violin, viola, cello and double bass) and a number of other instruments (e.g., viols and gambas used in early music from the Baro ...

Sample And Hold
In electronics, a sample and hold (also known as sample and follow) circuit is an analog device that samples (captures, takes) the voltage of a continuously varying analog signal and holds (locks, freezes) its value at a constant level for a specified minimum period of time. Sample and hold circuits and related peak detectors are the elementary analog memory devices. They are typically used in analog-to-digital converters to eliminate variations in input signal that can corrupt the conversion process.Kefauver and Patschke, p. 37. They are also used in electronic music, for instance to impart a random quality to successively-played notes. A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET (field effect transistor) switch and normally one operational amplifier.Horowitz and Hill, p. 220. To sample the input signal, the switch connects the capacitor to the output of a buffer amplifier. The buffer ampli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
