Triangle (musical Instrument)
The triangle is a musical instrument in the percussion family, and is classified as an idiophone in the Hornbostel-Sachs classification system. Triangles are made from a variety of metals including aluminum, beryllium copper, brass, bronze, iron, and steel. The metal is formed into a triangle shape by bending or casting methods. The instrument is usually held by a loop of some form of thread or wire at the top curve. The triangle theoretically has indefinite pitch, and produces a plurality of overtones when struck with an appropriate beater. History Iconography is the primary source for knowledge of the history of the triangle, and provides insight into the musical and social context in which the instrument developed. Some scholars believe the triangle to be a direct descendant of the ancient Egyptian sistrum. Others do not go quite so far, referring to the triangle as being "allied" with the sistrum throughout history, but not a direct descendant. It is thought that ...

Hand Percussion
Hand percussion is a percussion instrument that is held in the hand. They can be made from wood, metal or plastic, bottles stops and are usually shaken, scraped, or tapped with fingers or a stick. It includes all instruments that are not drums or pitched percussion instruments such as the marimba or the xylophone. Shakers A shaker (percussion) 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. Modern shakers are often cylinders made from metal wood or plastic containing small hard items such as seeds, stones, or plastic - an example is the Egg Shaker.There is another category of shaken instrument using jingles, little discs of metal which tap together when shaken. Tambourines fall into this category. Scrapers This can be a w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turquerie
Turquerie (anglicized as "Turkery"), "Turquoiserie" was the Turkish fashion in Western Europe from the 16th to 18th centuries for imitating aspects of Ottoman art and culture. Many different Western European countries were fascinated by the exotic and relatively unknown culture of the Ottoman ruling class, which was the center of the Ottoman Empire. This fashionable phenomenon became more popular through trading routes and increased diplomatic relationships between the Ottomans and the European nations, exemplified by the Franco-Ottoman alliance in 1715. Ambassadors and traders often returned home with tales of exotic places and souvenirs of their adventures. The movement was often reflected in the art of the period. Music, paintings, architecture, and artifacts were frequently inspired by the Ottoman styles and methods. Paintings in particular portrayed the Ottomans with bright colours and sharp contrasts, suggesting their interesting peculiarity and exotic nature. History o ...

Triangle Roll
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices ''A'', ''B'', and ''C'' is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. This article is about triangles in Euclidean geometry, and in particular, the Euclidean plane, except where otherwise noted. Types of triangle The terminology for categorizing triangles is more than two thousand years old, having been defined on the very first page of Euclid's Elements. The names used for modern classification are e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Line
A fishing line is a flexible, high-tensile cord used in angling to tether and pull in fish, in conjunction with at least one hook. Fishing lines are usually pulled by and stored in a reel, but can also be retrieved by hand, with a fixed attachment to the end of a rod, or via a motor. Fishing lines generally resemble a long, ultra-thin rope, with important attributes including length, material, weight and thickness. Other factors relevant to certain fishing environments include breaking strength, knot strength, UV resistance, castability, limpness, stretch, abrasion resistance, and visibility. Traditional fishing lines are made of silk, while most modern lines are made from synthetic polymers such as nylon, polyethylene or polyvinylidene fluoride ("fluorocarbon") and may come in monofilament or braided ( multifilament) forms. Terminology Fishing with a hook-and-line setup is called angling. Fish are caught when one are drawn by the bait/ lure dressed on the hook into swallow ...

Nylon
Nylon is a generic designation for a family of synthetic polymers composed of polyamides ( repeating units linked by amide links).The polyamides may be aliphatic or semi-aromatic. Nylon is a silk-like thermoplastic, generally made from petroleum, that can be melt-processed into fibers, films, or shapes. Nylon polymers can be mixed with a wide variety of additives to achieve many property variations. Nylon polymers have found significant commercial applications in fabric and fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging). History DuPont and the invention of nylon Researchers at DuPont began developing cellulose based fibers, culminating in the synthetic fiber rayon. DuPont's experience with rayon was an important precursor to its development and marketing of nylon. DuPont's invention of nylon spanned an eleven-year period, ranging from the initial resear ...

Overtone
An overtone is any resonant frequency above the fundamental frequency of a sound. (An overtone may or may not be a harmonic) In other words, overtones are all pitches higher than the lowest pitch within an individual sound; the fundamental is the lowest pitch. While the fundamental is usually heard most prominently, overtones are actually present in any pitch except a true sine wave. The relative volume or amplitude of various overtone partials is one of the key identifying features of timbre, or the individual characteristic of a sound. Using the model of Fourier analysis, the fundamental and the overtones together are called partials. Harmonics, or more precisely, harmonic partials, are partials whose frequencies are numerical integer multiples of the fundamental (including the fundamental, which is 1 times itself). These overlapping terms are variously used when discussing the acoustic behavior of musical instruments.Alexander J. Ellis (translating Hermann von Helmholtz): ...

Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Romantic Music
Romantic music is a stylistic movement in Western Classical music associated with the period of the 19th century commonly referred to as the Romantic era (or Romantic period). It is closely related to the broader concept of Romanticism—the intellectual, artistic and literary movement that became prominent in Western culture from approximately 1798 until 1837. Romantic composers sought to create music that was individualistic, emotional, dramatic and often programmatic; reflecting broader trends within the movements of Romantic literature, poetry, art, and philosophy. Romantic music was often ostensibly inspired by (or else sought to evoke) non-musical stimuli, such as nature, literature, poetry, super-natural elements or the fine arts. It included features such as increased chromaticism and moved away from traditional forms. Background The Romantic movement was an artistic, literary, and intellectual movement that originated in the second half of the 18th century in ...

Janissary
A Janissary ( ota, یڭیچری, yeŋiçeri, , ) was a member of the elite infantry units that formed the Ottoman Sultan's household troops and the first modern standing army in Europe. The corps was most likely established under sultan Orhan (1324–1362), during the Viziership of Alaeddin. Janissaries began as elite corps made up through the devşirme system of child levy, by which Christian Albanians, Romanians, Armenians, Bulgarians, Croats, Greeks and Serbs were taken, levied, subjected to circumcision and conversion to Islam, and incorporated into the Ottoman army. They became famed for internal cohesion cemented by strict discipline and order. Unlike typical slaves, they were paid regular salaries. Forbidden to marry before the age of 40 or engage in trade, their complete loyalty to the Sultan was expected. By the seventeenth century, due to a dramatic increase in the size of the Ottoman standing army, the corps' initially strict recruitment policy was relaxed. Civil ...

Naqareh
The ''naqareh'', ''naqqāra'', ''nagara'' or ''nagada'' is a Middle Eastern drum with a rounded back and a hide head, usually played in pairs. It is thus a membranophone of the kettle drum variety. The term ''naqqāra'' (), also ''naqqarat'', ''naqqarah'', ''naqqåre'', ''nakkare'', ''nagora'' comes from the Arabic verb ''naqr-'' that means "to strike, beat". The instrument was also adopted in Europe following the Crusades, and known as the naccaire or naker. Construction The rounded section of a naqqara is made of baked clay, while the flat side consists of treated skin fastened around the rim with string which is tightened over the back of the bow Playing This percussion instrument is often played in pairs, where one ''naqqara'' will produce low pitch beats called ''nar'' and the other for the high pitch beats. The instruments are beaten with short wooden sticks bent outward at the upper ends called ''damka''. Varieties Iraq and the other Arab countries ''Naqqārāt'' is t ...

Davul
The davul, dhol, tapan, atabal or tabl is a large double-headed drum that is played with mallets. It has many names depending on the country and region. These drums are commonly used in the music of the Middle East and the Balkans. These drums have both a deep bass sound and a thin treble sound due to their construction and playing style, where different heads and sticks are used to produce different sounds on the same drum. Names Some names of davuls include: *''dhol'' ( hy, դհոլ) *''dawola/davola'' ( syr, ܛܲܒܼܠܵܐ) *''dohol'' ( fa, دهل dohol) *''doli'' ( ka, დოლი doli) *''davul'' ( tr, davul, lit=drum) *''dahol'' ( ku, dahol, sdh, Dîweł) *''davil'' ( ta, davil) *''davula'' ( Sinhala: දවුල) *''tupan'' ( Goranian: tupan) *''daul'', ''tǎpan'', ''tupan'' ( bg, тъпан, тупан) *''goč'', ''tapan'', ''tupan'' ( sr, гоч, тапан, тупан) *''tapan, tupan'' ( mk, тапан, тупан) *''tobă/dobă'' ( ro , tobă) *''tabl'' ( ...
