Percussion Mallet
A percussion mallet or beater is an object used to strike or beat a percussion instrument in order to produce its sound. The term beater is slightly more general. A mallet is normally held in the hand while a beater may be foot or mechanically operated, for example in a bass drum pedal. The term drum stick is less general still, but still applied to a wide range of beaters. Some mallets, such as a triangle beater, are normally used only with a specific instrument, while others are used on many different instruments. Often, mallets of differing material and hardness are used to create different timbres on the same types of instrument (e.g. using either wooden or yarn mallets on a xylophone). Some mallets, such as vibraphone mallets, are normally just called mallets, others have more specialized names including: * Drum sticks, of many types, some used with a wide variety of instruments,. * Rutes, used with many instruments. * Brushes, used particularly with snare drum but ...

Mallet Bag
A mallet is a tool used for imparting force on another object, often made of rubber or sometimes wood, that is smaller than a maul or beetle, and usually has a relatively large head. The term is descriptive of the overall size and proportions of the tool, and not the materials it may be made of, though most mallets have striking faces that are softer than steel. Mallets are used in various industries, such as upholstery work, and a variety of other general purposes. It is a tool of preference for wood workers using chisels with plastic, metal, or wooden handles, as they give a softened strike with a positive drive. * Wooden mallets are usually used in carpentry to knock wooden pieces together, or to drive dowels ,chisels and to apply pressure on joints. A wooden mallet will not deform the striking end of a metal tool, as most metal hammers would. It is also used to reduce the force driving the cutting edge of a chisel, giving better control. Hardwood mallets are also used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crash Cymbal
A crash cymbal is a type of cymbal that produces a loud, sharp "crash" and is used mainly for occasional accents, as opposed to a ride cymbal. It can be mounted on a stand and played with a drum stick, or by hand in pairs. One or two crash cymbals are a standard part of a drum kit. Suspended crash cymbals are also used in bands and orchestras, either played with a drumstick or rolled with a pair of mallets to produce a slower, swelling crash. Sometimes a drummer may hit two different crash cymbals in a kit at the same time to produce a very loud accent, usually in rock music. Although crash cymbals range in thickness from paper-thin to very heavy, all crash cymbals have a fairly thin edge. They are typically in diameter, but sizes down to and up to are manufactured. Custom crash cymbals up to in diameter have been used by big bands. Different thicknesses are used for different kinds of music, and the alloy for each manufacturer's models varies. A thick cymbal is likely to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspended Cymbal
Classical suspended cymbal A suspended cymbal is any single cymbal played with a stick or beater rather than struck against another cymbal. Common abbreviations used are "sus. cym.," or "sus. cymb." (with or without the period). Most drum kits contain at least two suspended cymbals: a crash cymbal and a ride cymbal. History The term comes from the modern orchestra, in which the term ''cymbals'' normally refers to a pair of clash cymbals. The first suspended cymbals used in the modern orchestra were one of a pair of orchestral cymbals, supported by hanging it bell upwards (''i.e.'', with concavity opening downward) by its strap. This technique is still used, at times, but has largely been replaced by specialised cymbals with larger mounting holes that can be mounted on a cymbal stand. Occasionally the term ''suspended cymbal'' is still used in the original sense of one of a pair of orchestral cymbals hung by its strap, and this is the usage in older scores and may be the wish ...

Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marimba
The marimba () is a musical instrument in the percussion family that consists of wooden bars that are struck by mallets. Below each bar is a resonator pipe that amplifies particular harmonics of its sound. Compared to the xylophone, the timbre of the marimba is warmer, deeper, more resonant, and more pure. It also tends to have a lower range than that of a xylophone. Typically, the bars of a marimba are arranged chromatically, like the keys of a piano. The marimba is a type of idiophone. Today, the marimba is used as a solo instrument, or in ensembles like orchestras, marching bands (typically as a part of the front ensemble), percussion ensembles, brass and concert bands, and other traditional ensembles. Etymology and terminology The term ''marimba'' refers to both the traditional version of this instrument and its modern form. Its first documented use in the English language dates back to 1704. The term is of Bantu origin, deriving from the prefix meaning 'many' and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timpani Mallets
Timpani (; ) or kettledrums (also informally called timps) are musical instruments in the percussion family. A type of drum categorised as a hemispherical drum, they consist of a membrane called a 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 classical orchestra by the last third of the 18th century. Today, they are used in many types of ensembles, including concert bands, marching bands, orchestras, and even in some rock bands. ''Timpani'' is an Italian p ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Acrylic Resin
186 px, Polyhydroxyethylmethacrylate is a typical acrylate resin. An acrylic resin is a thermoplastic or thermosetting plastic substance typically derived from acrylic acid, methacrylic acid and acrylate monomers such as butyl acrylate and or methacrylate monomers such as methyl methacrylate. Thermoplastic acrylics designate a group of acrylic resins typically containing both a high molecular weight and a high glass transition temperature which exhibit lacquer dry capability. Acrylic resins designed for use in two component systems for crosslinking with isocyanate are referred to as polyols and are made with the monomers previously mentioned as well as hydroxy monomers such as hydroxy ethyl methacrylate. Acrylic resins are produced in different liquid carriers such as a hydrocarbon solvent (solventborne acrylics or solution acrylics solventborne acrylic selector) or water in which case they are referred to as emulsions or dispersions and they are also provided in 100% solids be ...

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 research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...
