Ligature (instrument)
A ligature is a device which holds a reed onto the mouthpiece of a single-reed instrument such as a saxophone or clarinet. The ligature must secure the reed firmly against the table of the mouthpiece while allowing it to vibrate freely. The earliest ligatures were lengths of string wrapped over the reed and tied. Iwan Müller invented a metal ligature to replace twine. String is still used by clarinetists, especially in Germany. Modern German mouthpieces have a groove cut into the outside of the mouthpiece to facilitate wrapping with a string ligature. Some modern clarinetists even opt to use shoestring as a ligature substitute as it is more easily adjustable than string. Other modern clarinetists use electrical tape as a ligature. A ligature must be placed properly in order to allow best performance on a reed instrument. The ligature must be placed at least halfway down the stock of the reed and the screws must not be overtightened, in order to allow free vibration and not disto ...

4 Ligaturen
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers 2, two + three + 5, five + 7, seven is the only sum of four consecutive prime numbers that yields an Parity (mathematics), odd prime number, 17 (number), seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and 5, five, which are the first two Fermat primes, like 17 ( ...

Reed (music)
A reed (or lamella) is a thin strip of material that vibrates to produce a sound on a musical instrument. Most woodwind instrument reeds are made from ''Arundo donax'' ("Giant cane") or synthetic material. Tuned reeds (as in harmonicas and accordions) are made of metal or synthetics. Musical instruments are classified according to the type and number of reeds. The earliest types of single-reed instruments used idioglottal reeds, where the vibrating reed is a tongue cut and shaped on the tube of cane. Much later, single-reed instruments started using heteroglottal reeds, where a reed is cut and separated from the tube of cane and attached to a mouthpiece of some sort. By contrast, in an uncapped double reed instrument (such as the oboe and bassoon), there is no mouthpiece; the two parts of the reed vibrate against one another. Single reeds Single reeds are used on the mouthpieces of clarinets and saxophones. The back of the reed is flat and is placed against the mouthpiece. These ...

Mouthpiece (woodwind)
The mouthpiece of a woodwind instrument is that part of the instrument which is placed partly in the player's mouth. Single-reed instruments, capped double-reed instruments, and fipple flutes have mouthpieces while exposed double-reed instruments (apart from those using pirouettes) and open flutes do not. The characteristics of a mouthpiece and reed can play a significant role on the sound of the instrument. Single-reed instruments On single-reed instruments, such as the clarinet and saxophone, the mouthpiece is that part to which the reed is attached. Its function is to provide an opening through which air enters the instrument and one end of an air chamber to be set into vibration by the interaction between the air stream and the reed. Single-reed mouthpieces are basically wedge shaped, with the reed placed against the surface closest to the player's lower lip (the ''table''). The player's breath causes the reed to vibrate. The reed beats against the mouthpiece, and in turn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-reed Instrument
A single-reed instrument is a woodwind instrument that uses only one reed to produce sound. The very earliest single-reed instruments were documented in ancient Egypt, as well as the Middle East, Greece, and the Roman Empire. The earliest types of single-reed instruments used idioglottal reeds, where the vibrating reed is a tongue cut and shaped on the tube of cane. Much later, single-reed instruments started using heteroglottal reeds, where a reed is cut and separated from the tube of cane and attached to a mouthpiece of some sort. By contrast, in a double reed instrument (such as the oboe and bassoon), there is no mouthpiece; the two parts of the reed vibrate against one another. Reeds are traditionally made of cane and produce sound when air is blown across or through them. The type of instruments that use a single reed are clarinets and saxophone. The timbre of a single and double reed instrument is related to the harmonic series caused by the shape of the corpus. E.g. the ...

Saxophone
The saxophone (often referred to colloquially as the sax) is a type of single-reed woodwind instrument with a conical body, usually made of brass. As with all single-reed instruments, sound is produced when a reed on a mouthpiece vibrates to produce a sound wave inside the instrument's body. The pitch is controlled by opening and closing holes in the body to change the effective length of the tube. The holes are closed by leather pads attached to keys operated by the player. Saxophones are made in various sizes and are almost always treated as transposing instruments. Saxophone players are called '' saxophonists''. The saxophone is used in a wide range of musical styles including classical music (such as concert bands, chamber music, solo repertoire, and occasionally orchestras), military bands, marching bands, jazz (such as big bands and jazz combos), and contemporary music. The saxophone is also used as a solo and melody instrument or as a member of a horn section in som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarinet
The clarinet is a musical instrument in the woodwind family. The instrument has a nearly cylindrical bore and a flared bell, and uses a single reed to produce sound. Clarinets comprise a family of instruments of differing sizes and pitches. The clarinet family is the largest such woodwind family, with more than a dozen types, ranging from the BB♭ contrabass to the E♭ soprano. The most common clarinet is the B soprano clarinet. German instrument maker Johann Christoph Denner is generally credited with inventing the clarinet sometime after 1698 by adding a register key to the chalumeau, an earlier single-reed instrument. Over time, additional keywork and the development of airtight pads were added to improve the tone and playability. Today the clarinet is used in classical music, military bands, klezmer, jazz, and other styles. It is a standard fixture of the orchestra and concert band. Etymology The word ''clarinet'' may have entered the English language via the Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwan Müller
Ivan Müller, sometimes spelled Iwan Mueller (1786 in Reval, Estonia – 1854 in Bückeburg), was a clarinetist, composer and inventor who at the beginning of the 19th century was responsible for a major step forward in the development of the clarinet, the air-tight pad. Biography Müller was born in Reval (present-day Tallinn), at that time a city with a strong Baltic German community in the Governorate of Estonia, part of the Russian Empire. He became a chamber musician in Saint Petersburg before he was twenty. At the same time, he was constantly striving to improve the clarinet, with new types of keywork. At the time, the standard clarinet used flat brass plates covered in soft leather to cover the toneholes. Since these leaked air, the number of them had to be kept to a minimum, which meant that notes outside the main scale of the clarinet (''accidentals'') had to be obtained by complicated fingerings which were difficult to play quickly and rarely were in tune.

Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1, ...

Naugahyde
Naugahyde is an American brand of artificial leather. Naugahyde is a composite knit fabric backing and expanded polyvinyl chloride (PVC) coating. It was developed by Byron A. Hunter, senior chemist at the United States Rubber Company, and is now manufactured and sold by the corporate spin-off Uniroyal Engineered Products, LLC. Its name, first used as a trademark in 1936, comes from the name of Naugatuck, Connecticut, where it was first produced. It is now manufactured in Stoughton, Wisconsin. Uses The primary use for Naugahyde is as a substitute for leather in upholstery. In this application it is very durable and can be easily maintained by wiping with a damp sponge or cloth. Being a synthetic product, it is supplied in long rolls, allowing large sections of furniture to be covered seamlessly, unlike animal hides. General Motors for several decades used the material in several of its vehicles, with the term "Cordaveen" and later "Madrid-grain vinyl" for Buick, "Morocceen" ...

Leather
Leather is a strong, flexible and durable material obtained from the tanning, or chemical treatment, of animal skins and hides to prevent decay. The most common leathers come from cattle, sheep, goats, equine animals, buffalo, pigs and hogs, and aquatic animals such as seals and alligators. Leather can be used to make a variety of items, including clothing, footwear, handbags, furniture, tools and sports equipment, and lasts for decades. Leather making has been practiced for more than 7,000 years and the leading producers of leather today are China and India. Animal rights groups claim that modern commercial leather making and the consumption of its products is unethically killing animals. According to the life-cycle assessment (LCA) report for the United Nations Industrial Development Organization, 99% of the raw hides and skins used in the production of leather derive from animals raised for meat and/or dairy production. Critics of tanneries claim that they engage in uns ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
