Kettle Drums
Timpani (; ) or kettledrums (also informally called timps) are musical instruments in the percussion instrument, percussion family. A type of drum categorised as a hemispherical drum, they consist of a Membranophone, membrane called a drumhead, head stretched over a large bowl traditionally made of copper. Thus timpani are an example of kettle drums, also known as vessel drums and semispherical drums, whose body is similar to a section of a sphere whose cut conforms the head. Most modern timpani are ''pedal timpani'' and can be tuned quickly and accurately to specific pitches by skilled players through the use of a movable foot-pedal. They are played by striking the head with a specialized drum stick called a ''timpani stick'' or ''timpani mallet''. Timpani evolved from military drums to become a staple of the European classical music, classical orchestra by the last third of the 18th century. Today, they are used in many types of Musical ensemble, ensembles, including concert ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Membranophone
A membranophone is any musical instrument which produces sound primarily by way of a vibrating stretched membrane. It is one of the four main divisions of instruments in the original Hornbostel-Sachs scheme of musical instrument classification. According to Sachs, material, shape, skin(s), skin fastening, playing positions, and manner of playing. Hornbostel-Sachs The Hornbostel-Sachs scheme of musical instrument classification divides membranophones in a numeric taxonomy based on how the sound is produced: *21: by hitting the drumskin with a hand or object (most common form, including the timpani and snare drum) *22: by pulling a knotted string attached to the drumskin (common in Indian drums, and can be considered an example of a chordophone as well) *23: by rubbing the drumskin with a hand or object (common in Irish traditional music, an example is the bodhran) *24: by modifying sounds through a vibrating membrane (unusual form, including the kazoo) Length and breadth ...

Marching Band
A marching band is a group of instrumental musicians who perform while marching, often for entertainment or competition. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military-style, that includes an associated organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags, rifles, and sabres. Marching bands are generally categorized by function, size, age, instrumentation, marching style, and type of show they perform. In addition to traditional parade performances, many marching bands also perform field shows at sporting events and marching band competitions. Increasingly, marching bands perform indoor concerts that implement many songs, traditions, and flair from outside performances. In some cases, at higher ...

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Fiberglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of 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 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, 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. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or GF ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pliny The Elder
Gaius Plinius Secundus (AD 23/2479), called Pliny the Elder (), was a Roman author, naturalist and natural philosopher, and naval and army commander of the early Roman Empire, and a friend of the emperor Vespasian. He wrote the encyclopedic ''Naturalis Historia'' (''Natural History''), which became an editorial model for encyclopedias. He spent most of his spare time studying, writing, and investigating natural and geographic phenomena in the field. His nephew, Pliny the Younger, wrote of him in a letter to the historian Tacitus: Among Pliny's greatest works was the twenty-volume work ''Bella Germaniae'' ("The History of the German Wars"), which is no longer extant. ''Bella Germaniae'', which began where Aufidius Bassus' ''Libri Belli Germanici'' ("The War with the Germans") left off, was used as a source by other prominent Roman historians, including Plutarch, Tacitus and Suetonius. Tacitus—who many scholars agree had never travelled in Germania—used ''Bella Germani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sieve
A sieve, fine mesh strainer, or sift, is a device for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word ''sift'' derives from ''sieve''. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer (see Colander), meanwhile, is a form of sieve used to separate suspended solids from a liquid by filtration. Industrial strainer Some industrial strainers available are simplex basket strainers, duplex basket strainers, T-strainers and Y-strainers. Simple basket strainers are used to protect valuable or sensitive equipment in systems that are meant to be shut down temporarily. Some commonly used strainers are bell mouth strainers, foot valve strainers, basket strainers. Most processing industries (mainly pharmaceutical, coatings and liquid food indu ...

Symphonia
Symphonia (Greek ) is a much-discussed word, applied at different times to the bagpipe, the drum, the hurdy-gurdy, and finally a kind of clavichord. The sixth of the musical instruments enumerated in Book of Daniel, (verses 5, 10 and 15), translated "dulcimer" in the 17th-century King James Bible; in all probability it refers to the bagpipe. The symphonia, signifying drum, is mentioned in Isidore of Seville's ''Etymologiae'' under the entries for tympanum and sambuca. "Symphonia" or ''chifonie'' was applied during the 13th and 14th centuries, in the Latin countries more especially, to the hurdy-gurdy. "Symphonia" is applied by Praetorius to an instrument which he classed with the clavichord, cites spinet, regal and virginals The virginals (or virginal) is a keyboard instrument of the harpsichord family. It was popular in Europe during the late Renaissance and early Baroque periods. Description A virginal is a smaller and simpler rectangular or polygonal form of ... ...

Isidore Of Seville
Isidore of Seville ( la, Isidorus Hispalensis; c. 560 – 4 April 636) was a Spanish scholar, theologian, and archbishop of Seville. He is widely regarded, in the words of 19th-century historian Montalembert, as "the last scholar of the ancient world". At a time of disintegration of classical culture, aristocratic violence and widespread illiteracy, Isidore was involved in the conversion of the Arian Visigothic kings to Catholicism, both assisting his brother Leander of Seville and continuing after his brother's death. He was influential in the inner circle of Sisebut, Visigothic king of Hispania. Like Leander, he played a prominent role in the Councils of Toledo and Seville. His fame after his death was based on his ''Etymologiae'', an etymological encyclopedia that assembled extracts of many books from classical antiquity that would have otherwise been lost. This work also helped standardize the use of the period ( full stop), comma, and colon. Since the early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etymologiae
''Etymologiae'' (Latin for "The Etymologies"), also known as the ''Origines'' ("Origins") and usually abbreviated ''Orig.'', is an etymological encyclopedia compiled by Isidore of Seville (c. 560–636) towards the end of his life. Isidore was encouraged to write the book by his friend Braulio, Bishop of Saragossa. ''The Etymologies'' summarized and organized a wealth of knowledge from hundreds of classical sources; three of its books are derived largely from Pliny the Elder's '' Natural History''. Isidore acknowledges Pliny, but not his other principal sources, namely Cassiodorus, Servius and Solinus. The work contains whatever Isidore, an influential Christian bishop, thought worth keeping. ''Etymologiae'' covers an encyclopedic range of topics. Etymology, the origins of words, is prominent, but the work covers among other things: grammar, rhetoric, mathematics, geometry, music, astronomy, medicine, law, the Roman Catholic Church and heretical sects, pagan philosophers, lang ...

Charanga (Cuba)
Charanga is a traditional ensemble that plays Cuban dance music. They made Cuban dance music popular in the 1940s and their music consisted of heavily son-influenced material, performed on European instruments such as violin and flute by a Charanga orchestra. (Chomsky 2004, p. 199). The style of music that is most associated with a Charanga is termed 'Danzón', and is an amalgam of both European classical music and African rhythms. Origins "Scholars agree that Spain and parts of West and Central Africa provided the most crucial influences in the development of Cuban popular and religious music. But in the case of charanga, the contributions of French and Haitian influences cannot be ignored. Charanga began its history in the early nineteenth century when Haitians, both African and French, escaped the island's revolution. They brought with them a love for the French contredanse, a multi-sectional dance form that evolved into the danzón, the quintessential charanga style. ...

Timbales
Timbales () or pailas are shallow single-headed drums with metal casing. They are shallower than single-headed tom-toms and usually tuned much higher, especially for their size.Orovio, Helio 1981. ''Diccionario de la música cubana: biográfico y técnico''. Entries for ''Paila criolla''; ''Timbal criollo''. They were developed as an alternative to classical timpani in Cuba in the early 20th century and later spread across Latin America and the United States. Timbales are struck with wooden sticks on the heads and shells, although bare hands are sometimes used. The player (called a ''timbalero'') uses a variety of stick strokes, rim shots, and rolls to produce a wide range of percussive expression during solos and at transitional sections of music, and usually plays the shells (or auxiliary percussion such as a cowbell or cymbal) to keep time in other parts of the song. The shells and the typical pattern played on them are referred to as ''cáscara''. Common stroke patterns incl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latinisation (literature)
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attribut ...
