Music 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, ...

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 ...

Pump Organ
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 & ...

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 ...

Middle C
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 ...

Manual (music)
A manual is a musical keyboard designed to be played with the hands, on an instrument such as a pipe organ, harpsichord, clavichord, electronic organ, melodica, or synthesizer. The term "manual" is used with regard to any hand keyboard on these instruments to distinguish it from the pedalboard, which is a keyboard that the organist plays with their feet. It is proper to use "manual" rather than "keyboard", then, when referring to the hand keyboards on any instrument that has a pedalboard. Music written to be played only on the manuals (instead of using the pedals) can be designated by manualiter (first attested in 1511, but particularly common in the 17th and 18th centuries). Overview Organs and synthesizers can, and usually do, have more than one manual; most home instruments have two manuals, while most larger organs have two or three. Elaborate pipe organs and theater organs can have four or more manuals. The manuals are set into the organ console (or "keydesk"). The lay ...

Registration (organ)
Registration is the technique of choosing and combining the stops of a pipe organ in order to produce a particular sound. ''Registration'' can also refer to a particular combination of stops, which may be recalled through combination action. The registration chosen for a particular piece will be determined by a number of factors, including the composer's indications (if any are given), the time and place in which the piece was composed, the organ the piece is played upon, and the acoustic environment within which the organ resides. Pitch and timbre The pitch produced by a pipe is a function of its length. An organ stop may be tuned to sound (or "speak at") the pitch normally associated with the key that is pressed (the "unison pitch"), or it may speak at a fixed interval above or below this pitch (an "octave pitch"). Some stops are tuned to notes "in-between" the octaves and are called "Mutations" (see below). The pitch of a rank of pipes is denoted by a number on the stop knob. ...

Clavinet
The Clavinet is an electrically amplified clavichord invented by Ernst Zacharias and manufactured by the Hohner company of Trossingen, West Germany, from 1964 to 1982. The instrument produces sounds by a rubber pad striking a point on a tensioned string, and was designed to resemble the Renaissance-era clavichord. Although originally intended for home use, the Clavinet became popular on stage, and could be used to create electric guitar sounds on a keyboard. It is strongly associated with Stevie Wonder, who used the instrument extensively, particularly on his 1972 hit "Superstition", and was regularly featured in rock, funk and reggae music throughout the 1960s and 1970s. Modern digital keyboards can emulate the Clavinet sound, but there is also a grass-roots industry of repairers who continue to maintain the instrument. Description The Clavinet is an electromechanical instrument that is usually used in conjunction with a keyboard amplifier. Most models have 60 keys ranging ...

Pentatonic Scale
A pentatonic scale is a musical scale with five notes per octave, in contrast to the heptatonic scale, which has seven notes per octave (such as the major scale and minor scale). Pentatonic scales were developed independently by many ancient civilizations and are still used in various musical styles to this day. There are two types of pentatonic scales: those with semitones (hemitonic) and those without (anhemitonic). Types Hemitonic and anhemitonic Musicology commonly classifies pentatonic scales as either ''hemitonic'' or ''anhemitonic''. Hemitonic scales contain one or more semitones and anhemitonic scales do not contain semitones. (For example, in Japanese music the anhemitonic ''yo'' scale is contrasted with the hemitonic ''in'' scale.) Hemitonic pentatonic scales are also called "ditonic scales", because the largest interval in them is the ditone (e.g., in the scale C–E–F–G–B–C, the interval found between C–E and G–B). (This should not be confu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flat (music)
In music, flat (Italian bemolle for "soft B") means "lower in pitch". Flat is the opposite of sharp, which is a raising of pitch. In musical notation, flat means "lower in pitch by one semitone (half step)", notated using the symbol which is derived from a stylised lowercase 'b'. For instance, the music below has a key signature with three flats (indicating either E major or C minor) and the note, D, has a flat accidental. : Under twelve-tone equal temperament, D for instance is enharmonically equivalent to C, and G is equivalent to F. In any other tuning system, such enharmonic equivalences in general do not exist. To allow extended just intonation, composer Ben Johnston uses a sharp as an accidental to indicate a note is raised 70.6 cents (ratio 25:24), and a flat to indicate a note is lowered 70.6 cents. In intonation, flat can also mean "slightly lower in pitch" (by some unspecified amount). If two simultaneous notes are slightly out-of-tune, the lower-pitched o ...

Sharp (music)
In music, sharp, dièse (from French), or diesis (from Greek) means, "higher in pitch". More specifically, in musical notation, sharp means "higher in pitch by one semitone (half step)". Sharp is the opposite of flat, which is a lowering of pitch. A sharp symbol, , is used in key signatures or as an accidental. For instance, the music below has a key signature with three sharps (indicating either A major or F minor, the relative minor) and the note, A, has a sharp accidental. : Under twelve-tone equal temperament, B, for instance, sounds the same as, or is enharmonically equivalent to, C natural (C), and E is enharmonically equivalent to F. In other tuning systems, such enharmonic equivalences in general do not exist. To allow extended just intonation, composer Ben Johnston uses a sharp to indicate a note is raised 70.6 cents (ratio 25:24), or a flat to indicate a note is lowered 70.6 cents. In intonation, sharp can also mean "slightly higher in pitch" (by some unspec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivory
Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. Besides natural ivory, ivory can also be produced synthetically, hence (unlike natural ivory) not requiring the retrieval of the material from animals. Tagua nuts can also be carved like ivory. The trade of finished goods of ivory products has its origins in the Indus Valley. Ivory is a main product that is seen in abundance and was used for trading in Harappan civilization.
