Percussion instrument
–
A percussion instrument is a musical instrument that is sounded by being struck or scraped by a beater, struck, scraped or rubbed by hand, or struck against another similar instrument. The percussion family is believed to include the oldest musical instruments, the percussion section of an orchestra most commonly contains instruments such as timpani, snare drum, bass drum, cymbals, triangle and tambourine. However, the section can also contain non-percussive instruments, such as whistles and sirens, percussive techniques can also be applied to the human body, as in body percussion. On the other hand, keyboard instruments, such as the celesta, are not normally part of the percussion section, Percussion instruments may play not only rhythm, but also melody and harmony. Percussion is commonly referred to as the backbone or the heartbeat of an ensemble, often working in close collaboration with bass instruments. In jazz and other popular ensembles, the pianist, bassist, drummer. Most classical pieces written for full orchestra since the time of Haydn and Mozart are orchestrated to place emphasis on the strings, woodwinds, however, often at least one pair of timpani is included, though they rarely play continuously. Rather, they serve to provide additional accents when needed, in the 18th and 19th centuries, other percussion instruments have been used, again generally sparingly. The use of percussion instruments became more frequent in the 20th century classical music, in almost every style of music, percussion plays a pivotal role. In classic jazz, one almost immediately thinks of the rhythm of the hi-hats or the ride cymbal when the word swing is spoken. Because of the diversity of instruments, it is not uncommon to find large musical ensembles composed entirely of percussion. Rhythm, melody, and harmony are all represented in these ensembles, music for pitched percussion instruments can be notated on a staff with the same treble and bass clefs used by many non-percussive instruments. Music for percussive instruments without a pitch can be notated with a specialist rhythm or percussion-clef. The word percussion has evolved from Latin terms, percussio, as a noun in contemporary English it is described in Wiktionary as the collision of two bodies to produce a sound. Hornbostel–Sachs has no high-level section for percussion, Most percussion instruments are classified as idiophones and membranophones.1 Concussion idiophones or clappers, played in pairs and beaten against each other, such as zills and clapsticks. 111.2 Percussion idiophones, includes many percussion instruments played with the hand or by a mallet, such as the hang, gongs and the xylophone. 21 Struck drums, includes most types of drum, such as the timpani, snare drum, (Included in most drum sets or 412. Stringed instruments played with such as the hammered dulcimer

Hand percussion
–
Hand percussion is a term used to indicate a percussion instrument of any type from any culture that is held in the hand. They can be made from wood, metal or plastic and are usually either shaken and it is a useful category in terms of a large percussion orchestra in that it identifies all instruments that are not drums or pitched percussion such as marimba and xylophone. A shaker is any instrument that makes a noise when shaken, historically they were naturally occurring items such as seed pods. A caxixi is a basketwork shaker with a gourd base. Gourds are used all over the world and covered with a net with shells or seeds to create an instrument such as the shekere and this can be a wood, metal or plastic instrument which has ridges on its body. Often known as Guiro, rhythms are created by running a stick up. Gourds or bamboo have traditionally used as they have a resonant hollow body. A common type from Asia is a carved wooden frog which has ridges cut on its back and its mouth, cowbells originate from the bells tied around the necks of livestock. They are any type of hand held bell tapped with fingers and they occur all over the world and are used extensively in Latin Percussion music and often found as part of a standard Rock Drum Kit. The name cowbell usually refers to a single bell, the Agogô bell usually refers to a double or triple bell. The triangle is a piece of steel bent in the shape of a triangle tapped with another piece of steel and it is suspended on one hand which can be open and closed to alter the sound. Very commonly used in South American Music to give a persistent high pitched pulse, tapping two sticks together is the simplest form of hand percussion, and has developed a place in traditional music all over the world. Indigenous Australians use clapping sticks alongside the didgeridoo, and claves are a part of South American Music. There are a variety of hand held drums such as tamborim which fall into the Hand Percussion category

Dowel
–
A dowel is a solid cylindrical rod, usually made from wood, plastic, or metal. In its original manufactured form, a dowel is called a dowel rod, dowel rods are often cut into short lengths called dowel pins. Dowels are employed in numerous, diverse applications including axles in toys, detents, structural reinforcements in cabinet making, to make a dowel, a piece of wood is split or whittled to a size slightly bigger than desired and then driven through the hole in the dowel plate. The sharp edges of the hole shear off the excess wood, a second approach to cutting dowels is to rotate a piece of oversized stock past a fixed knife, or alternatively, to rotate the knife around the stock. Machines based on this principle emerged in the 19th century, frequently, these are small bench-mounted tools. For modest manufacturing volumes, wood dowels are typically manufactured on industrial dowel machines based on the principles as the rotary cutters described above. Such machines may employ interchangeable cutting heads of varying diameters, thus enabling the machines to be changed to manufacture different dowel diameters. Typically, the mechanism is open-ended, with material guides at the machines entry, since the 19th century, some of these dowel machines have had power feed mechanisms to move the stock past the cutting mechanism. High-volume dowel manufacturing is done on a shaper, which simultaneously forms multiple dowels from a single piece of rectangular stock. These machines employ two wide, rotating cutting heads, one above the stock and one below it, the heads have nearly identical cutting profiles so that each will form an array of adjoined, side-by-side half dowels. The wooden dowel rod used in woodworking applications is commonly cut into dowel pins, some woodworkers make their own dowel pins, while others purchase dowel pins precut to the required length and diameter. When dowels are glued into blind holes, a common case in dowel-based joinery, there must be a path for air. If no provision is made to relieve the pressure of air and glue. An old solution to this problem is to plane a flat on the side of the dowel, some dowel pins are Fluted with multiple parallel grooves along their length to serve the same purpose. When two pieces of wood are to be joined by dowels embedded in holes, there are numerous methods for aligning the holes. Dowel centers are simple and inexpensive tools for aligning opposing blind holes, various commercial systems, such as Dowelmax, have been devised to solve this problem. Alternative joinery methods may be used in place of conventional dowel pins, such as Miller dowels, biscuit joiners, spline joints, and proprietary tools such as the Domino jointer. The word dowel was used in Middle English, it appears in Wycliffes Bible translation in a list of the parts of a wheel. and the spokis, cognates with other Germanic languages suggest that the word is much older

Rosewood
–
Rosewood refers to any of a number of richly hued timbers, often brownish with darker veining but found in many different hues. All genuine rosewoods belong to the genus Dalbergia and it is best known as Brazilian Rosewood, but also as Bahia rosewood. This wood has a sweet smell, which persists for many years. Another classic rosewood comes from Dalbergia latifolia known as Indian rosewood or sonokeling and it is native to India and is also grown in plantations elsewhere in Pakistan. Madagascar rosewood, known as bois de rose, is prized for its red color. It is overexploited in the wild, despite a 2010 moratorium on trade and illegal logging, throughout southeast Asia Dalbergia oliveri is harvested for use in woodworking. It has a fragrant and dense grain near the core, however the outer sapwood is soft. Dalbergia cultrata that has variegated burgundy to light color, a blackwood timber is sold as Burmese Rosewood. Products built with rosewood based engineered woods are sold as Malaysian Rosewood or as Dalbergia oliveri, some rosewood comes from Dalbergia retusa, also known as the Nicaraguan rosewood or as palisander is controlled by CITES under Appendix 2 which allows some commercial activity. Several species are known as Guatemalan rosewood or Panama rosewood, D. tucerencis, D. tucarensis, stevensonii, also on CITES Appendix 2, is used for marimba keys, guitar parts, clarinets and other musical and ornamental applications. Not all species in the large genus Dalbergia yield rosewoods, only about a species do. The woods of some species in the genus Dalbergia are notable—even famous—woods in their own right, African blackwood, cocobolo, kingwood. The woods of some species are usable for tool handles at best. The timber trade will sell many timbers under the name due to some similarities. A fair number of these come from other legume genera. Another that may be found in market from Southeast Asia is Pterocarpus indicus, Dalbergia sissoo is timber from rosewood species from India and Bangladesh, usually known as Sheesham or North-Indian Rosewood. It is extremely dense and has mild rot resistance, but it is porous and its exterior is soft and it is used for making cabinets, flooring and carving. It is exported as quality veneers, due to its after work quality when sealed and dyed, it is often sold as genuine rosewood or as teak

Ebony
–
Ebony is a dense black hardwood, most commonly yielded by several different species in the genus Diospyros, which also contains the persimmons. Ebony is dense enough to sink in water and it is finely-textured and has a very smooth finish when polished, making it valuable as an ornamental wood. The word ebony derives from the Ancient Egyptian hbny, via the Ancient Greek ἔβενος, by way of Latin, mauritius ebony, Diospyros tesselaria, was largely exploited by the Dutch in the 17th century. Some species in the genus Diospyros yield an ebony with similar physical properties, ebony has a long history of use, with carved pieces having been found in Ancient Egyptian tombs. By the end of the 16th century, fine cabinets for the trade were made of ebony in Antwerp. Within a short time, such cabinets were also being made in Paris, where their makers became known as ébénistes, many plectra, or guitar picks, are made from this black wood. Traditionally, the pieces in chess sets were made from ebony. Modern East Midlands-style lace-making bobbins, also being small, are made of ebony. Due to its strength, many handgun grips and rifle fore-end tips are made of ebony, as a result of unsustainable harvesting, many species yielding ebony are now considered threatened. Africa in particular has had most of its indigenous ebony cut down illegally, in some countries like Sri Lanka, ebony is a protected species and selling of ebony logs is illegal, due to the woods rarity and high price. In 2012, the Gibson Guitar company was raided by the US Fish and Wildlife Service for violations of the Lacey Act of 1900, pete Lowry, ebony and rosewood expert at the Missouri Botanical Garden, calls the Madagascar wood trade the equivalent of Africas blood diamonds. Ebony, when ground into fine dust, results in a flammable, due to the high toxicity of ebony in powdered form, its use in construction work requires government certification in several South Asian countries.

Fiberglass
–
Fiberglass is a type of fiber-reinforced plastic where the reinforcement fiber is specifically glass fiber. The glass fiber may be arranged, flattened into a sheet. The plastic matrix may be a polymer matrix – most often based on thermosetting polymers such as epoxy, polyester resin. The glass fibers are made of various types of glass depending upon the fiberglass use and these glasses all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes boron. To be used in fiberglass, glass fibers have to be made very low levels of defects. Fiberglass is a lightweight material and is used for many products. Although it is not as strong and stiff as composites based on fiber, it is less brittle. Its bulk strength and weight are also better than many metals, other common names for fiberglass are glass-reinforced plastic, glass-fiber reinforced plastic or GFK. Because glass fiber itself is referred to as fiberglass, the composite is also called fiberglass reinforced plastic. This article will adopt the convention that fiberglass refers to the glass fiber reinforced composite material. A patent for this method of producing glass wool was first applied for in 1933, Owens joined with the Corning company in 1935 and the method was adapted by Owens Corning to produce its patented fibreglas in 1936. Originally, fibreglas was a wool with fibers entrapping a great deal of gas, making it useful as an insulator. A suitable resin for combining the fibreglass with a plastic to produce a material was developed in 1936 by du Pont. The first ancestor of modern polyester resins is Cyanamids resin of 1942, peroxide curing systems were used by then. With the combination of fiberglass and resin the gas content of the material was replaced by plastic and this reduced the insulation properties to values typical of the plastic, but now for the first time the composite showed great strength and promise as a structural and building material. Confusingly, many glass fiber composites continued to be called fiberglass, ray Greene of Owens Corning is credited with producing the first composite boat in 1937, but did not proceed further at the time due to the brittle nature of the plastic used. In 1939 Russia was reported to have constructed a boat of plastic materials. The first car to have a body was a 1946 prototype of the Stout Scarab

Plastic
–
Plastic is a material consisting of any of a wide range of synthetic or semi-synthetic organic compounds that are malleable and can be molded into solid objects. Plastics are typically organic polymers of high mass, but they often contain other substances. They are usually synthetic, most commonly derived from petrochemicals, due to their relatively low cost, ease of manufacture, versatility, and imperviousness to water, plastics are used in an enormous and expanding range of products, from paper clips to spaceships. They have already displaced many traditional materials, such as wood, stone, horn and bone, leather, paper, metal, glass, and ceramic, in most of their former uses. In developed countries, about a third of plastic is used in packaging, other uses include automobiles, furniture, and toys. In the developing world, the ratios may be different - for example, the worlds first fully synthetic plastic was bakelite, invented in New York in 1907 by Leo Baekeland who coined the term plastics. Toward the end of the century, one approach to this problem was met with wide efforts toward recycling, the word plastic is derived from the Greek πλαστικός meaning capable of being shaped or molded, from πλαστός meaning molded. The common word plastic should not be confused with the technical adjective plastic, used for insulating parts in electrical fixtures, paper laminated products, thermally insulation foams. Problems include the probability of moldings naturally being dark colors, One of the most expensive commercial polymers. It forms the basis of artistic and commercial acrylic paints when suspended in water with the use of other agents, polytetrafluoroethylene – Heat-resistant, low-friction coatings, used in things like non-stick surfaces for frying pans, plumbers tape and water slides. It is more known as Teflon. Urea-formaldehyde – One of the aminoplasts and used as an alternative to phenolics. Used as an adhesive and electrical switch housings. Early plastics were bio-derived materials such as egg and blood proteins, in 1600 BC, Mesoamericans used natural rubber for balls, bands, and figurines. Treated cattle horns were used as windows for lanterns in the Middle Ages, materials that mimicked the properties of horns were developed by treating milk-proteins with lye. In the 1800s, as industrial chemistry developed during the Industrial Revolution, the development of plastics also accelerated with Charles Goodyears discovery of vulcanization to thermoset materials derived from natural rubber. Parkesine is considered the first man-made plastic, the plastic material was patented by Alexander Parkes, In Birmingham, UK in 1856. It was unveiled at the 1862 Great International Exhibition in London, parkesine won a bronze medal at the 1862 Worlds fair in London

Son cubano
–
Son cubano is a genre of music and dance that originated in the highlands of eastern Cuba during the late 19th century. It is a genre that amalgamates elements of Spanish and African origin. Among its fundamental Hispanic components are the style, lyrical metre. On the other hand, its characteristic clave rhythm, call and response structure, around 1909 the son reached Havana, where the first recordings were made in 1917. This marked the start of its expansion throughout the island, becoming Cubas most popular, while early groups had between three and five members, during the 1920s the sexteto became the genres primary format. By the 1930s, many bands had incorporated a trumpet, becoming septetos, and in the 1940s a larger type of ensemble featuring congas and piano became the norm, the cojunto. Besides, the son became one of the ingredients in the jam sessions known as descargas that flourished during the 1950s. The international presence of the son can be traced back to the 1930s when many bands toured Europe and North America, similarly, radio broadcasts of son became popular in West Africa and the Congos, leading to the development of hybrid genres such as Congolese rumba. In the 1960s, New Yorks music scene prompted the rapid success of salsa, in Spanish, the word son, from Latin sonus, denotes a pleasant sound, particularly a musical one. In eastern Cuba, the term began to be used to refer to the music of the highlands towards the late 19th century, to distinguish it from similar genres from other countries, the term son cubano is most commonly used. In Cuba, various qualifiers are used to distinguish the variants of the genre. These include son montuno, son oriental, son santiaguero and son habanero, Son singers are generally known as soneros, and the verb sonear describes not only their singing but also their vocal improvisation. The adjective soneado refers to songs and styles which incorporate the tempo and syncopation of the son, generally, there is an explicit diffenrece between styles that incorporate elements of the son partially or totally, as evidenced by the distinction between bolero soneado and bolero-son. The term sonora refers to conjuntos with smoother trumpet sections such as Sonora Matancera and Sonora Ponceña, although the history of Cuban music dates back to the 16th century, the son is a relatively recent musical invention whose precursors emerged in the mid-to-late 19th century. Musicologists agree that the ancestors of the son appeared in Cubas Oriente Province. These forms flourished in the context of rural parties such as guateques, where bungas were known to perform, such early guitars are thought to have given rise to the tres some time around 1890 in Baracoa. The addition of a section composed of percussion instruments such as the bongó. Due to the very little historiographical and ethnomusicological research devoted to the son and this fallacy stemmed from the apocryphal origin story of a folk song known as Son de Má Teodora

Clave (rhythm)
–
The clave is a rhythmic pattern used as a tool for temporal organization in Afro-Cuban music. It is present in a variety of such as Abakuá music, rumba, conga, son, mambo, salsa, songo, timba. The five-stroke clave pattern represents the core of many Afro-Cuban rhythms. The clave pattern originated in sub-Saharan African music traditions, where it essentially the same function as it does in Cuba. In ethnomusicology, clave is known as a key pattern, guide pattern, phrasing referent, timeline. The clave pattern is used in North American popular music as a motif or simply a form of rhythmic decoration. Clave is also the name of the played on claves. Just as a keystone holds an arch in place, the clave pattern holds the rhythm together in Afro-Cuban music, the two main clave patterns used in Afro-Cuban music are known in North America as son clave and the rumba clave. Both are used as bell patterns across much of Africa, son and rumba clave can be played in either a triple-pulse or duple-pulse structure. The contemporary Cuban practice is to write the duple-pulse clave in a measure of 44. It is also written in a measure in ethnomusicological writings about African music. Although they subdivide the beats differently, the 128 and 44 versions of each share the same pulse names. The correlation between the triple-pulse and duple-pulse forms of clave, as well as patterns, is an important dynamic of sub-Saharan-based rhythm. Every triple-pulse pattern has its duple-pulse correlative, son clave has strokes on,1, 1a, 2&, 3&,4. || Both clave patterns are used in rumba, what we now call son clave used to be the key pattern played in Havana-style yambú and guaguancó. Some Havana-based rumba groups still use son clave for yambú, the musical genre known as son probably adopted the clave pattern from rumba when it migrated from eastern Cuba to Havana at the beginning of the 20th century. During the nineteenth century, African music and European music sensibilities were blended together in original Cuban hybrids, Cuban popular music became the conduit through which sub-Saharan rhythmic elements were first codified within the context of European music theory. The first written music based on clave was the Cuban danzón

Music of Africa
–
The traditional music of Africa, given the vastness of the continent, is historically ancient, rich and diverse, with different regions and nations of Africa having many distinct musical traditions. Traditional music in most of the continent is passed down orally and is not written, the music and dance of the African diaspora, formed to varying degrees on African musical traditions, include American music and many Caribbean genres, such as soca, calypso and zouk. Latin American music genres such as the rumba, conga, bomba, cumbia and samba were also founded on the music of enslaved Africans, and have in turn influenced African popular music. North Africa is the seat of ancient Egypt and Carthage, civilizations with strong ties to the ancient Near East, eventually, Egypt fell under Persian rule followed by Greek and Roman rule, while Carthage was later ruled by Romans and Vandals. North Africa was later conquered by the Arabs, who established the region as the Maghreb of the Arab world, like the musical genres of the Nile Valley and the Horn of Africa, its music has close ties with Middle Eastern music and utilizes similar melodic modes. North African music has a range, from the music of ancient Egypt to the Berber. The regions art music has for centuries followed the outline of Arabic and Andalusian classical music, with these may be grouped the music of Sudan and of the Horn of Africa, including the music of Eritrea, Ethiopia, Djibouti and Somalia. Somali music is pentatonic, using five pitches per octave in contrast to a heptatonic scale such as the major scale. The music of the Ethiopian highlands uses a fundamental modal system called qenet, of which there are four modes, tezeta, bati, ambassel. Three additional modes are variations on the above, tezeta minor, bati major, some songs take the name of their qenet, such as tizita, a song of reminiscence. The ethnomusicological pioneer Arthur Morris Jones observed that the shared rhythmic principles of Sub-Saharan African music traditions constitute one main system, similarly, master drummer and scholar C. K. Ladzekpo affirms the profound homogeneity of sub-Saharan African rhythmic principles. African traditional music is frequently functional in nature, performances may be long and often involve the participation of the audience. None of this is performed outside its intended context and much of it is associated with a particular dance. Some of it, performed by musicians, is sacral music or ceremonial. The southern region includes the music of South Africa, Lesotho, Swaziland, Botswana, Namibia, the central region includes the music of Chad, the Central African Republic, the Democratic Republic of the Congo and Zambia, including Pygmy music. Southern, Central and West Africa are similarly in the broad Sub-Saharan musical tradition, besides vocalisation, which uses various techniques such as complex hard melisma and yodel, a wide array of musical instruments are used. Additionally, string instruments are used, with the lute-like oud. Other percussion instruments include many rattles and shakers, such as the kosika, rain stick, bells, also, Africa has lots of other types of drums, and lots of flutes, and lots of stringed and wind instruments
