The xylophone (; ) is a musical instrument in the percussion family that consists of wooden bars struck by mallets. Each bar is an idiophone tuned to a pitch of a musical scale, whether pentatonic or heptatonic in the case of many African and Asian instruments, diatonic in many western children's instruments, or chromatic for orchestral use. The term ''xylophone'' may be used generally, to include all such instruments such as the marimba, balafon and even the semantron. However, in the orchestra, the term ''xylophone'' refers specifically to a chromatic instrument of somewhat higher pitch range and drier timbre than the marimba, and these two instruments should not be confused. A person who plays the xylophone is known as a ''xylophonist'' or simply a ''xylophone player''. The term is also popularly used to refer to similar instruments of the lithophone and metallophone types. For example, the Pixiphone and many similar toys described by the makers as xylophones have bars of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Idiophone
An idiophone is any musical instrument that creates sound primarily by the vibration of the instrument itself, without the use of air flow (as with aerophones), strings (chordophones), membranes (membranophones) or electricity ( electrophones). It is the first of the four main divisions in the original Hornbostel–Sachs system of musical instrument classification (see List of idiophones by Hornbostel–Sachs number). The early classification of Victor-Charles Mahillon called this group of instruments ''autophones''. The most common are struck idiophones, or concussion idiophones, which are made to vibrate by being struck, either directly with a stick or hand (like the wood block, singing bowl, steel tongue drum, handpan, triangle or marimba) or indirectly, with scraping or shaking motions (like maracas or flexatone). Various types of bells fall into both categories. A common plucked idiophone is the Jew's harp. According to Sachs, idiophones Etymology The word ...

Orchestra
An orchestra (; ) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments: * String instruments, such as the violin, viola, cello, and double bass * Woodwinds, such as the flute, oboe, clarinet, bassoon, and occasional saxophone * Brass instruments, such as the French horn (commonly known as the "horn"), trumpet, trombone, cornet, and tuba, and sometimes euphonium * Percussion instruments, such as the timpani, snare drum, bass drum, cymbals, triangle, tambourine, tam-tam and mallet percussion instruments Other instruments such as the piano, harpsichord, pipe organ, and celesta may sometimes appear in a fifth keyboard section or may stand alone as soloist instruments, as may the concert harp and, for performances of some modern compositions, electronic instruments, and guitars. A full-size Western orchestra may sometimes be called a or phil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gourd
Gourds include the fruits of some flowering plant species in the family Cucurbitaceae, particularly '' Cucurbita'' and '' Lagenaria''. The term refers to a number of species and subspecies, many with hard shells, and some without. Many gourds have large, bulbous bodies and long necks, such as Dipper Gourds, many variations of Bottle Gourd and caveman club gourds. One of the earliest domesticated types of plants, subspecies of the bottle gourd, '' Lagenaria siceraria'', have been discovered in archaeological sites dating from as early as 13,000 BC. Gourds have had numerous uses throughout history, including as tools, musical instruments, objects of art, film, and food. Terminology ''Gourd'' is occasionally used to describe crop plants in the family Cucurbitaceae, like pumpkins, cucumbers, squash, luffa, and melons. More specifically, ''gourd'' refers to the fruits of plants in the two Cucurbitaceae genera '' Lagenaria'' and '' Cucurbita'', or also to their hollow, dried-ou ...

Resonators
A resonator is a device or system that exhibits resonance or resonant behavior. That is, it naturally oscillates with greater amplitude at some frequencies, called resonant frequencies, than at other frequencies. The oscillations in a resonator can be either electromagnetic or mechanical (including acoustic). Resonators are used to either generate waves of specific frequencies or to select specific frequencies from a signal. Musical instruments use acoustic resonators that produce sound waves of specific tones. Another example is quartz crystals used in electronic devices such as radio transmitters and quartz watches to produce oscillations of very precise frequency. A cavity resonator is one in which waves exist in a hollow space inside the device. In electronics and radio, microwave cavities consisting of hollow metal boxes are used in microwave transmitters, receivers and test equipment to control frequency, in place of the tuned circuits which are used at lower fre ...

Transposing Instrument
A transposing instrument is a musical instrument for which music notation is not written at concert pitch (concert pitch is the pitch on a non-transposing instrument such as the piano). For example, playing a written middle C on a transposing instrument produces a pitch other than middle C; that sounding pitch identifies the interval of transposition when describing the instrument. Playing a written C on clarinet or soprano saxophone produces a concert B (i.e. B at concert pitch), so these are referred to as B instruments. Providing transposed music for these instruments is a convention of musical notation. The instruments do not transpose the music; rather, their music is written at a transposed pitch. Where chords are indicated for improvisation they are also written in the appropriate transposed form. For some instruments, a written C sounds as a C but is in a different octave; these instruments are said to transpose "at the octave". Pitches on the double bass sound an ...

Fibre-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, boron, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. History Bakelite was the first fibre-reinforced plastic. Leo Baekeland had originally set out to find a replacement for shellac (made from the excretion of lac bugs). Chemists had begun to recognize that many natural resins and fibres were polymers, and Baekeland investigated the reactions of phenol an ...

Fiberglass
Fiberglass (American English) or fibreglass (English in the Commonwealth of Nations, Commonwealth English) is a common type of fibre-reinforced plastic, fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic Matrix (composite), matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than Carbon-fiber-reinforced polymers, carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins ...

Cocobolo
Cocobolo is a tropical hardwood of Central American trees belonging to the genus ''Dalbergia''. Only the heartwood of cocobolo is used; it is usually orange or reddish-brown, often with darker irregular traces weaving through the wood. The heartwood changes color after being cut and can be polished to a lustrous, glassy finish. Being quite dense and sometimes having a relative density of over 1.0, it will sink in water. The sapwood (not often used) is a creamy yellow with a sharp boundary between it and the heartwood. Provenance Cocobolo is yielded by two to four closely related species of the genus ''Dalbergia'', of which the best known is ''Dalbergia retusa'', a fair-sized tree, reported to reach in height and in diameter; it probably is the species contributing most of the wood in the trade. Because of the high value of the timber, the trees yielding it have been heavily exploited, so they have become rare outside of national parks, reserves, and plantations. Only small amou ...

Padauk
''Pterocarpus'' is a pantropical tree genus in the Fabaceae family. It belongs to the subfamily Faboideae, and was recently assigned to the informal monophyletic ''Pterocarpus'' clade within the Dalbergieae. Most species of ''Pterocarpus'' yield valuable timber traded as padauk (or padouk), usually pronounced or ; other common names are mukwa or narra. The west African species may be traded as African rosewood. '' P. santalinus'' also yields the most precious red sandalwood in China known as Zitan. The wood from the narra tree ('' P. indicus'') and the Burmese padauk tree ('' P. macrocarpus'') is marketed as amboyna when it has grown in the burl form. The scientific name is Latinized Ancient Greek and means "wing fruit", referring to the unusual shape of the seed pods in this genus. Uses Padauk wood is obtained from several species of ''Pterocarpus''. All padauks are of African or Asian origin. Padauks are valued for their toughness, stability in use, and decorativeness, mos ...

Rosewood
Rosewood is any of a number of richly hued hardwoods, often brownish with darker veining, but found in other colours. It is hard, tough, strong, and dense. True rosewoods come from trees of the genus '' Dalbergia'', but other woods are often called rosewood. Rosewood takes a high polish and is used for luxury furniture-making, flooring, musical instruments, and turnery. True rosewoods Genuine rosewoods belong to the genus '' Dalbergia''. The pre-eminent rosewood appreciated in the Western world is the wood of '' Dalbergia nigra''. It is best known as "Brazilian rosewood", but also as "Bahia rosewood". This wood has a strong, sweet smell, which persists for many years, explaining the name ''rosewood''. Another classic rosewood comes from '' Dalbergia latifolia'', known as (East) Indian rosewood or ''sonokeling'' (Indonesia). It is native to India and is also grown in plantations elsewhere in Pakistan (Chiniot). Madagascar rosewood ('' Dalbergia maritima''), known as ''bois ...
