121-721: The "Slingerland Banjo Company" was founded by Henry Heanon (H.H.) Slingerland (1875–1946) in 1912. Slingerland had won a correspondence school of music in a card game aboard one of the gaming boats that once cruised Lake Michigan. He then opened a music school in Chicago, and soon turned to manufacturing musical instruments as well. As its name indicated, the company started out producing banjos while importing ukuleles from Germany, but set up its own production because it could not meet demand. Soon, they produced their own musical instruments and eventually, also guitars (including electric guitars from 1936 or earlier). Production of snare drums

242-492: A bone flute to signal the start of a hunt does so without thought of the modern notion of "making music". Musical instruments are constructed in a broad array of styles and shapes, using many different materials. Early musical instruments were made from "found objects" such as shells and plant parts. As instruments evolved, so did the selection and quality of materials. Virtually every material in nature has been used by at least one culture to make musical instruments. One plays

363-402: A horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The exact date and specific origin of the first device considered a musical instrument, is widely disputed. The oldest object identified by scholars as

484-481: A whole-tone scale . These excavations, carried out by Leonard Woolley in the 1920s, uncovered non-degradable fragments of instruments and the voids left by the degraded segments that, together, have been used to reconstruct them. The graves these instruments were buried in have been carbon dated to between 2600 and 2500 BC, providing evidence that these instruments were used in Sumeria by this time. Archaeologists in

605-461: A Radio King drum was created from a single piece of steam-bent maple with solid maple reinforcement rings to assist in keeping the drum round under the pressure of the metal hardware attached to it. Single-ply wood drums are known for their resonance and bright tone. Radio King bass drums and tom-toms were made from mahogany, with maple reinforcement hoops. These drums are known for their "thuddy" sound; very warm, with quick decay. The popularity of

726-427: A barrel is worn and needs to be replaced. The end of the chamber, freebore and leade (the unrifled portion of the barrel just forward of the chamber), as well as the first few centimeters or few inches of rifling, in rifles are subject to very high temperatures—as the energy content of rifle propellants can exceed 3500 kJ/kg—and pressures that can exceed 380 MPa (55,114 psi). The propellant gases act similarly as

847-475: A bath surface tension less than 35 dyn/cm is necessary to prevent plating solution from becoming airborne when bubbles rise to the surface and pop. This requires a frequent cycle of treating the bath with a wetting agent fume suppressant and confirming the effect on surface tension. Usually, surface tension is measured with a stalagmometer or tensiometer . This method is, however, tedious and suffers from inaccuracy (errors up to 22 dyn/cm have been reported), and

968-423: A better historical picture. Until the 19th century AD, European-written music histories began with mythological accounts mingled with scripture of how musical instruments were invented. Such accounts included Jubal , descendant of Cain and "father of all such as handle the harp and the organ" ( Genesis 4:21) Pan , inventor of the pan pipes , and Mercury , who is said to have made a dried tortoise shell into

1089-552: A broader set of conditions (such as oxidation resistance), and bulking material for worn parts to restore their original dimensions. It is very hard, measuring between 65 and 69 HRC (also based on the base metal's hardness). Hard chrome tends to be thicker than decorative chrome, with standard thicknesses in non-salvage applications ranging from 20 to 40 μm, but it can be an order of magnitude thicker for extreme wear resistance requirements, in such cases 100 μm or thicker provides optimal results. Unfortunately, such thicknesses emphasize

1210-451: A challenge. Despite even the efforts of two organized international summits attended by noted composers like Hector Berlioz , no standard could be agreed upon. The evolution of traditional musical instruments slowed beginning in the 20th century. Instruments such as the violin, flute, french horn, and harp are largely the same as those manufactured throughout the eighteenth and nineteenth centuries. Gradual iterations do emerge; for example,

1331-593: A complementary color. In the last years of the Korean War , the US contemplated banning chrome in favor of several cheaper processes (such as plating with zinc and then coating with shiny plastic). In 2007, a Restriction of Hazardous Substances Directive (RoHS) was issued banning several toxic substances for use in the automotive industry in Europe, including hexavalent chromium , which is used in chrome plating. However, chrome plating

1452-435: A drastic increase in the number and variety of musical instruments. However, identifying and classifying the instruments remains a challenge due to the lack of artistic interpretations. For example, stringed instruments of uncertain design called nevals and asors existed, but neither archaeology nor etymology can clearly define them. In her book A Survey of Musical Instruments , American musicologist Sibyl Marcuse proposes that

1573-764: A fiddle would; both were prominent folk instruments in the Middle Ages. Southern Europeans played short and long lutes whose pegs extended to the sides, unlike the rear-facing pegs of Central and Northern European instruments. Idiophones such as bells and clappers served various practical purposes, such as warning of the approach of a leper . The ninth century revealed the first bagpipes , which spread throughout Europe and had many uses from folk instruments to military instruments. The construction of pneumatic organs evolved in Europe starting in fifth-century Spain , spreading to England in about 700. The resulting instruments varied in size and use from portable organs worn around

1694-540: A great relief of Amenhotep III , and are of particular interest because similar designs have been found in far-reaching places such as Tbilisi , Georgia and among the Native American Yaqui tribe. The people of Mesopotamia preferred stringed instruments , as evidenced by their proliferation in Mesopotamian figurines, plaques, and seals. Innumerable varieties of harps are depicted, as well as lyres and lutes,

1815-546: A large horseshoe magnet. Slingerland ceased making electric instruments in 1940 in order to exclusively focus on producing percussion instruments. The company remained in the Slingerland family until 1970, but continued to be a prominent drum manufacturer throughout the 1970s. After introducing the Magnum series in 1982, Slingerland lost its footing, and the company folded in 1986. Slingerland changed ownership multiple times until it

1936-732: A long violent period of war and destruction. This period saw the Kassites destroy the Babylonian empire in Mesopotamia and the Hyksos destroy the Middle Kingdom of Egypt . When the Pharaohs of Egypt conquered Southwest Asia in around 1500 BC, the cultural ties to Mesopotamia were renewed and Egypt's musical instruments also reflected heavy influence from Asiatic cultures. Under their new cultural influences,

2057-460: A melody. In contrast, pre-Columbian South American civilizations in areas such as modern-day Peru , Colombia , Ecuador , Bolivia , and Chile were less advanced culturally but more advanced musically. South American cultures of the time used pan-pipes as well as varieties of flutes, idiophones, drums, and shell or wood trumpets. An instrument that can be attested to the Iron Age Celts

2178-466: A mixture of timbres, a development needed for the complexity of music of the time. Trumpets evolved into their modern form to improve portability, and players used mutes to properly blend into chamber music . Beginning in the seventeenth century, composers began writing works to a higher emotional degree. They felt that polyphony better suited the emotional style they were aiming for and began writing musical parts for instruments that would complement

2299-632: A musical instrument by interacting with it in some way — for example, by plucking the strings on a string instrument , striking the surface of a drum , or blowing into an animal horn. Researchers have discovered archaeological evidence of musical instruments in many parts of the world. One disputed artifact (the Divje Babe flute ) has been dated to 67,000 years old, but consensus solidifies around artifacts dated back to around 37,000 years old and later. Artifacts made from durable materials, or constructed using durable methods, have been found to survive. As such,

2420-690: A musical instrument, is a simple flute , dated back 50,000–60,000 years. Many scholars date early flutes to about 40,000 years ago. Many historians believe that determining the specific date of musical instrument invention is impossible, as the majority of early musical instruments were constructed of animal skins, bone, wood, and other non-durable, bio-degradable materials. Additionally, some have proposed that lithophones , or stones used to make musical sounds—like those found at Sankarjang in India—are examples of prehistoric musical instruments. Musical instruments developed independently in many populated regions of

2541-644: A result of Gibson's bankruptcy auction to a private individual who proceeded to liquidate the remaining stock via eBay. This included drums produced in Nashville and in Taiwan. On November 25, 2019, it was announced that DW Drums had taken over ownership of the Slingerland brand from Gibson. Slingerland's most famous product line is the Radio King series of drums. These drums were introduced in 1936–37, and remained Slingerland's flagship snare drums and drum sets until 1957, when

2662-414: A toxic mist of water and hexavalent chromium is released from the bath. Wet scrubbers are used to control these emissions. The liquid from the wet scrubbers is treated to precipitate the chromium and remove it from the wastewater before it is discharged. Additional toxic waste created from hexavalent chromium baths include lead chromates , which form in the bath because lead anodes are used. Barium

2783-608: A unique system of classifying their musical instruments according to their material makeup. In Vietnam, an archaeological discovery of a 2,000-year old stringed instrument gives important insights on early chordophones in Southeast Asia. Idiophones were extremely important in Chinese music, hence the majority of early instruments were idiophones. Poetry of the Shang dynasty mentions bells, chimes, drums, and globular flutes carved from bone,

2904-666: A wider variety of expression. Large orchestras rose in popularity and, in parallel, the composers determined to produce entire orchestral scores that made use of the expressive abilities of modern instruments. Since instruments were involved in collaborations of a much larger scale, their designs had to evolve to accommodate the demands of the orchestra. Some instruments also had to become louder to fill larger halls and be heard over sizable orchestras. Flutes and bowed instruments underwent many modifications and design changes—most of them unsuccessful—in efforts to increase volume. Other instruments were changed just so they could play their parts in

3025-403: Is hydrogen evolution reaction (HER), and the role of chromate is to scavenge H ions in a reaction that competes with H 2 evolution: The shine of plated chrome depends on whether microscopic cracks in the plating are visible on the surface. The dull appearance of some chrome layers is due to continuous cracks that propagate through the whole plated metal layer, while bright deposits appear in

3146-427: Is a device created or adapted to make musical sounds . In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist . The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as

3267-477: Is a technique of electroplating a thin layer of chromium onto a metal object. A chrome plated part is called chrome , or is said to have been chromed . The chromium layer can be decorative, provide corrosion resistance, facilitate cleaning, and increase surface hardness. Sometimes a less expensive substitute for chrome, such as nickel, may be used for aesthetic purposes. Chromium compounds used in electroplating are toxic . In most countries, their disposal

3388-460: Is also dependent on the current density, because a higher current density requires a higher temperature. Finally, the whole bath is agitated to keep the temperature steady and achieve a uniform deposition. One functional disadvantage of hexavalent chromium plating is low cathode efficiency, which results in bad throwing power . This means it leaves a non-uniform coating, with more on edges and less in inside corners and holes. To overcome this problem

3509-565: Is also not reliable, as it cannot always be determined when and how cultures contacted one another and shared knowledge. Sachs proposed that a geographical chronology until approximately 1400 is preferable, however, due to its limited subjectivity. Beyond 1400, one can follow the overall development of musical instruments over time. The science of marking the order of musical instrument development relies on archaeological artifacts, artistic depictions, and literary references. Since data in one research path can be inconclusive, all three paths provide

3630-584: Is also popular for the etching of nimonic alloys. Sometimes the component enters the chrome plating vat while electrically live. Sometimes the component has a conforming anode made from lead/tin or platinized titanium. A typical hard chrome vat plates at about 0.001 inches (25 μm) per hour. Some common industry specifications governing the chrome plating process are AMS 2460, AMS 2406, and MIL-STD-1501. Hexavalent chromium plating , also known as hex-chrome , Cr , and chrome(VI) plating, uses chromium trioxide (CrO 3 , also known as chromic anhydride) as

3751-497: Is also used to control the sulfate concentration, which leads to the formation of barium sulfate (BaSO 4 ). Trivalent chromium is intrinsically less toxic than hexavalent chromium. Because of the lower toxicity it is not regulated as strictly, which reduces overhead costs . Other health advantages include higher cathode efficiencies, which lead to less chromium air emissions; lower concentration levels, resulting in less chromium waste and anodes that do not decompose.

3872-635: Is among many indications that the Indus Valley and Sumerian cultures maintained cultural contact. Subsequent developments in musical instruments in India occurred with the Rigveda , or hymns. These songs used various drums, shell trumpets, harps, and flutes. Other prominent instruments in use during the early centuries AD were the snake charmer's double clarinet , bagpipes , barrel drums, cross flutes, and short lutes. In all, India had no unique musical instruments until

3993-678: Is dependent on the user's experience and capabilities. While they are effective for the control of toxic airborne chromium, many widely used wetting agent fume suppressants are toxic themselves because they contain perfluoroalkyl substances (PFAS), which are hazardous chemicals that can cause long-term health effects. This makes electroplating one of the jobs with the highest risk of occupational exposure to PFAS, but not as high as firefighters using fluorinated aqueous film forming foams . In addition to their detrimental effects on human health, PFAS are persistent pollutants that cause significant bioaccumulation and biomagnification , putting animals at

4114-488: Is described as one of the last drummers to play rock using "vintage weapons," besides Neil Hennessy of the punk rock band the Lawrence Arms . Jamie Oliver, veteran drummer of English punk rock band UK Subs , frequently appears live with his beloved vintage silver tone Slingerland. In addition, drummer Jean-Marc Butty uses vintage Slingerland Drums with PJ Harvey . Musical instrument A musical instrument

4235-425: Is designed to be aesthetically pleasing and durable. Thicknesses range from 2 to 20 μin (0.05 to 0.5 μm), however, they are usually between 5 and 10 μin (0.13 and 0.25 μm). The chromium plating is usually applied over bright nickel plating . Typical base materials include steel , aluminium , plastic , copper alloys, and zinc alloys. Decorative chrome plating is also very corrosion resistant and

4356-563: Is done from liquids comprising Cr species. Such solutions were avoided prior to ca. 2020, because of air-sensitivity and hydrogen evolution from aqueous Cr solutions. In the 2020s, it was discovered that chromous chloride has ca. 4.0 M solubility in water at room temperature (i.e. with H 2 O:Cr molar ratio around 14:1), and such liquids behave like supersaturated electrolytes with a reduced propensity toward hydrogen evolution. The best quality bright deposits are produced at relatively high current density of 20 mA/cm . Decorative chrome

4477-472: Is metal and contains no hexavalent chromium after it is rinsed, so chrome plating is not banned. Chrome-lining protects the barrel or chamber of arms from corrosion and makes these parts also easier to clean, but this is not the main purpose for lining a barrel or chamber. Chrome-lining was introduced in machine guns to increase the wear resistance and service life of highly stressed arms parts like barrels and chambers, allowing more rounds to be fired before

4598-435: Is misleading to arrange the development of musical instruments by workmanship, since cultures advance at different rates and have access to different raw materials. For example, contemporary anthropologists comparing musical instruments from two cultures that existed at the same time but differed in organization, culture, and handicraft cannot determine which instruments are more "primitive" . Ordering instruments by geography

4719-401: Is misleading, since advancements in musical instruments have sometimes reduced complexity. For example, construction of early slit drums involved felling and hollowing out large trees; later slit drums were made by opening bamboo stalks, a much simpler task. German musicologist Curt Sachs , one of the most prominent musicologists and musical ethnologists in modern times, argues that it

4840-413: Is more robust than hexavalent chromium because it can withstand current interruptions. One of the disadvantages when the process was first introduced was that decorative customers disapproved of the color differences. Companies now use additives to adjust the color. In hard coating applications, the corrosion resistance of thicker coatings is not quite as good as it is with hexavalent chromium. The cost of

4961-415: Is often used on car parts, tools and kitchen utensils. Thin dense chrome (TDC) differs from decorative chrome. While decorative chrome is applied primarily for aesthetic purposes with thin layers that provide a shiny finish, TDC, such as Armoloy , focuses on enhancing surface performance. It delivers wear resistance, corrosion protection, and hardness without adding significant thickness. TDC also avoids

5082-533: Is subject to different types of quality requirements depending on the application; for instance, the plating on hydraulic piston rods are tested for corrosion resistance with a salt spray test . Most bright decorative items affixed to cars are referred to as "chrome", meaning steel that has undergone several plating processes to protect it from weathering and moisture but the term passed on to cover any similar-looking shiny decorative auto parts, including silver plastic trim pieces in casual terminology. Triple plating

5203-424: Is the carnyx , which is dated to c. 300 BC. The end of the bell, which was crafted from bronze, was into the shape of a screaming animal head which was held high above their heads. When blown into, the carnyx would emit a deep, harsh sound; the head also had a tongue which clicked when vibrated. It is believed the intention of the instrument was to use it on the battleground to intimidate their opponents. During

5324-418: Is the most expensive and durable process, which involves plating the steel first with copper and then nickel before the chromium plating is applied. Prior to the application of chrome in the 1920s, nickel electroplating was used. In the short production run prior to the US entry into World War II , the government banned plating to save chromium and automobile manufacturers painted the decorative pieces in

5445-488: Is tightly regulated. Some fume suppressants used to control the emission of airborne chromium from plating baths are also toxic, making disposal even more difficult. The preparation and chrome plating of a part typically includes some or all of these steps: There are many variations to this process, depending on the type of substrate being plated. Different substrates need different etching solutions, such as hydrochloric , hydrofluoric , and sulfuric acids . Ferric chloride

5566-475: Is used to make musical sounds . Once humans moved from making sounds with their bodies — for example, by clapping—to using objects to create music from sounds, musical instruments were born. Primitive instruments were probably designed to emulate natural sounds , and their purpose was ritual rather than entertainment. The concept of melody and the artistic pursuit of musical composition were probably unknown to early players of musical instruments. A person sounding

5687-730: Is wasted when grinding the piece back to desired dimensions. Modern engineered coatings do not suffer such drawbacks, which often price hard chrome out due to labor costs alone. Hard chrome replacement technologies outperform hard chrome in wear resistance, corrosion resistance, and cost. Hardness up to 80 HRC is not extraordinary for such materials. Modern engineered coatings applied using spray deposition can form layers of uniform thickness that often require no further polishing or machining. These coatings are often composites of polymers , metals, and ceramic powders or fibers as proprietary formulas protected by patents or as trade secrets, and thus are usually known by brand names. Hard chromium plating

5808-547: The Alboka (from Arab, al-buq or "horn") nowadays only alive in Basque Country . It must be played using the technique of the circular breathing. Southeast Asian musical innovations include those during a period of Indian influence that ended around 920 AD. Balinese and Javanese music made use of xylophones and metallophones , bronze versions of the former. The most prominent and important musical instrument of Southeast Asia

5929-572: The Bible and the Talmud . The Hebrew texts mention two prominent instruments associated with Jubal : the ugab (pipes) and kinnor (lyre). Other instruments of the period included the tof ( frame drum ), pa'amon (small bells or jingles), shofar , and the trumpet-like hasosra . The introduction of a monarchy in Israel during the 11th century BC produced the first professional musicians and with them

6050-570: The Chukchi people of the Russian Far East , the indigenous people of Melanesia , and many cultures of Africa . In fact, drums were pervasive throughout every African culture. One East African tribe, the Wahinda , believed it was so holy that seeing a drum would be fatal to any person other than the sultan. Humans eventually developed the concept of using musical instruments to produce melody , which

6171-524: The Han dynasty . Although civilizations in Central America attained a relatively high level of sophistication by the eleventh century AD, they lagged behind other civilizations in the development of musical instruments. For example, they had no stringed instruments; all of their instruments were idiophones, drums, and wind instruments such as flutes and trumpets. Of these, only the flute was capable of producing

6292-487: The Jiahu site of central Henan province of China have found flutes made of bones that date back 7,000 to 9,000 years, representing some of the "earliest complete, playable, tightly-dated, multinote musical instruments" ever found. Scholars agree that there are no completely reliable methods of determining the exact chronology of musical instruments across cultures. Comparing and organizing instruments based on their complexity

6413-615: The Royal Cemetery in the Sumerian city of Ur . These instruments, one of the first ensembles of instruments yet discovered, include nine lyres (the Lyres of Ur ), two harps , a silver double flute , a sistrum and cymbals . A set of reed-sounded silver pipes discovered in Ur was the likely predecessor of modern bagpipes . The cylindrical pipes feature three side holes that allowed players to produce

6534-480: The ground harp , ground zither , musical bow , and jaw harp . Recent research into usage wear and acoustics of stone artefacts has revealed a possible new class of prehistoric musical instrument, known as lithophones . Images of musical instruments begin to appear in Mesopotamian artifacts in 2800 BC or earlier. Beginning around 2000 BC, Sumerian and Babylonian cultures began delineating two distinct classes of musical instruments due to division of labor and

6655-545: The post-classical era . Musical instruments such as zithers appeared in Chinese writings around 12th century BC and earlier. Early Chinese philosophers such as Confucius (551–479 BC), Mencius (372–289 BC), and Laozi shaped the development of musical instruments in China, adopting an attitude toward music similar to that of the Greeks. The Chinese believed that music was an essential part of character and community, and developed

6776-441: The theremin . Musical instrument classification is a discipline in its own right, and many systems of classification have been used over the years. Instruments can be classified by their effective range, material composition, size, role, etc. However, the most common academic method, Hornbostel–Sachs , uses the means by which they produce sound. The academic study of musical instruments is called organology . A musical instrument

6897-468: The urghun ( organ ), shilyani (probably a type of harp or lyre ), salandj (probably a bagpipe ) and the lyra . The Byzantine lyra, a bowed string instrument, is an ancestor of most European bowed instruments, including the violin . The monochord served as a precise measure of the notes of a musical scale, allowing more accurate musical arrangements. Mechanical hurdy-gurdies allowed single musicians to play more complicated arrangements than

7018-439: The war effort . These drums were named the "Rolling Bomber" series, and are highly collectible. The Rock and Roll era of the 1960s and 1970s was a good time for many American drum companies, including Slingerland, although its main competitor, Ludwig , had the advantage of being endorsed by Ringo Starr , but Slingerland, too, produced drums in that era and had robust sales. Beside long time endorser Buddy Rich , Slingerland in

7139-550: The "New Violin Family" began in 1964 to provide differently sized violins to expand the range of available sounds. The slowdown in development was a practical response to the concurrent slowdown in orchestra and venue size. Despite this trend in traditional instruments, the development of new musical instruments exploded in the twentieth century, and the variety of instruments developed overshadows any prior period. Chrome plating Chrome plating (less commonly chromium plating )

7260-432: The "active Cr " also undergoes within less than 1 second a transition into "inactive Cr ", which is believed to be a polymeric hexa-aqua complex. Some complexes of Cr with ligand other than water can undergo relatively fast electroreduction to metallic chromium, and they are used in chromate-free chromium plating methods. A different school of thought suggests, that the main problem with chromium plating from Cr solution

7381-619: The "father" was the bigger or more energetic instrument, while the "mother" was the smaller or duller instrument. Musical instruments existed in this form for thousands of years before patterns of three or more tones would evolve in the form of the earliest xylophone . Xylophones originated in the mainland and archipelago of Southeast Asia , eventually spreading to Africa, the Americas, and Europe. Along with xylophones, which ranged from simple sets of three "leg bars" to carefully tuned sets of parallel bars, various cultures developed instruments such as

7502-436: The 1920s. By the 1970s, the Slingerland line of marching equipment had become very popular in marching bands, colleges, and drum corps. During the late 1970s, Slingerland introduced its TDR marching snare drum, with a novel strainer and synthetic-gut snare that produced a distinctive sound. Another late-70s innovation was the Slingerland cutaway multi-tenors that were carried in trio, quad, or quint arrangements. The cutaway design

7623-496: The 1970s garnered drummers Danny Seraphine with Chicago and Nigel Olsson , the drummer for Elton John , and Neil Peart of Rush . Short-lived in the 1970s was Slingerland's version of Ludwig Vistalite drums . They stopped production quickly after their introduction due to a patent infringement suit and a cease and desist warrant from Ludwig regarding Slingerland's foray into acrylic drums. These drums today remain collectible. Slingerland marching drums were produced as early as

7744-554: The General Butler Vagabonds all used Slingerland equipment in the late 1970s and early 1980s. In the early 1980s, Slingerland was gaining significant market share, but the company was sold, and corporate finances fell apart. By the late 1980s, Slingerland had fallen behind technologically, and Ludwig-Musser , and especially Pearl drums , began to pick up its market share. For most of the company's pre-1970s history, Slingerland's manufacturing processes were not standardized in

7865-557: The Middles Ages came from Asia. The lyre is the only musical instrument that may have been invented in Europe until this period. Stringed instruments were prominent in Middle Age Europe. The central and northern regions used mainly lutes, stringed instruments with necks , while the southern region used lyres, which featured a two-armed body and a crossbar. Various harps served Central and Northern Europe as far north as Ireland, where

7986-402: The Radio King model briefly disappeared from the product line. Between 1960 and 1962, Radio Kings were reintroduced. Older Radio Kings are obsessively collected by vintage drum enthusiasts. Gene Krupa and Buddy Rich were both Radio King endorsers. The original Radio King snare drum is distinguished by its construction: rather than several plies of mahogany , like most snare drums of the era,

8107-507: The activation step is done in the chromium bath. The chromium bath is a mixture of chromium trioxide and sulfuric acid , the ratio of which varies greatly between 75:1 to 250:1 by weight. This results in an extremely acidic bath (pH 0). The temperature and current density in the bath affect the brightness and final coverage. For decorative coating the temperature ranges from 35 to 45 °C (100 to 110 °F), but for hard coating it ranges from 50 to 65 °C (120 to 150 °F). Temperature

8228-624: The area. Rather, the history of musical instruments in the area begins with the Indus Valley civilization that emerged around 3000 BC. Various rattles and whistles found among excavated artifacts are the only physical evidence of musical instruments. A clay statuette indicates the use of drums, and examination of the Indus script has also revealed representations of vertical arched harps identical in design to those depicted in Sumerian artifacts. This discovery

8349-505: The changes to timbre and volume was a shift in the typical pitch used to tune instruments. Instruments meant to play together, as in an orchestra, must be tuned to the same standard lest they produce audibly different sounds while playing the same notes. Beginning in 1762, the average concert pitch began rising from a low of 377 vibrations to a high of 457 in 1880 Vienna. Different regions, countries, and even instrument manufacturers preferred different standards, making orchestral collaboration

8470-405: The chemicals is greater, but this is usually offset by greater production rates and lower overhead costs. In general, the process must be controlled more closely than in hexavalent chromium plating, especially with respect to metallic impurities. This means processes that are hard to control, such as barrel plating, are much more difficult using a trivalent chromium bath. Divalent chromium plating

8591-560: The cultural contacts seem to have dissipated; the lyre, a prominent ceremonial instrument in Sumer, did not appear in Egypt for another 800 years. Clappers and concussion sticks appear on Egyptian vases as early as 3000 BC. The civilization also made use of sistra, vertical flutes , double clarinets , arched and angular harps, and various drums. Little history is available in the period between 2700 BC and 1500 BC, as Egypt (and indeed, Babylon) entered

8712-404: The end of the chamber, freebore, leade and rifling. Hard chrome-lining protects the chamber, freebore, leade and rifling with a thin coat of wear resistant chrome. This significantly extends barrel life in arms that are fired for prolonged periods in full-auto or sustained rapid fire modes. Some arms manufacturers use Stellite-lining alloy as an alternative to hard chrome-lining to further increase

8833-496: The evolving class system. Popular instruments, simple and playable by anyone, evolved differently from professional instruments whose development focused on effectiveness and skill. Despite this development, very few musical instruments have been recovered in Mesopotamia . Scholars must rely on artifacts and cuneiform texts written in Sumerian or Akkadian to reconstruct the early history of musical instruments in Mesopotamia. Even

8954-484: The first bowed zithers appeared in China in the 9th or 10th century, influenced by Mongolian culture. India experienced similar development to China in the post-classical era; however, stringed instruments developed differently as they accommodated different styles of music. While stringed instruments of China were designed to produce precise tones capable of matching the tones of chimes, stringed instruments of India were considerably more flexible. This flexibility suited

9075-464: The first lyre . Modern histories have replaced such mythology with anthropological speculation, occasionally informed by archeological evidence. Scholars agree that there was no definitive "invention" of the musical instrument since the term "musical instrument" is subjective and hard to define. Among the first devices external to the human body that are considered instruments are rattles , stampers, and various drums . These instruments evolved due to

9196-454: The first such book was Sebastian Virdung 's 1511 treatise Musica getuscht und ausgezogen ('Music Germanized and Abstracted'). Virdung's work is noted as being particularly thorough for including descriptions of "irregular" instruments such as hunters' horns and cow bells, though Virdung is critical of the same. Other books followed, including Arnolt Schlick 's Spiegel der Orgelmacher und Organisten ('Mirror of Organ Makers and Organ Players')

9317-455: The flame from a cutting torch, the gases heating up the metal to red-hot state and the velocity tearing away metal. Under slow fire conditions, the affected areas are able to cool sufficiently in between shots. Under sustained rapid fire or automatic/cyclic fire there is no time for the heat to dissipate. The heat and pressure effects exerted by the hot propellant gasses and friction by the projectile can quickly cause damage by washing away metal at

9438-526: The following year, a treatise on organ building and organ playing. Of the instructional books and references published in the Renaissance era, one is noted for its detailed description and depiction of all wind and stringed instruments, including their relative sizes. This book, the Syntagma musicum by Michael Praetorius , is now considered an authoritative reference of sixteenth-century musical instruments. In

9559-457: The forerunner of modern stringed instruments such as the violin . Musical instruments used by the Egyptian culture before 2700 BC bore striking similarity to those of Mesopotamia, leading historians to conclude that the civilizations must have been in contact with one another. Sachs notes that Egypt did not possess any instruments that the Sumerian culture did not also possess. However, by 2700 BC

9680-402: The gods. Greeks played a variety of wind instruments they classified as aulos (reeds) or syrinx (flutes); Greek writing from that time reflects a serious study of reed production and playing technique. Romans played reed instruments named tibia , featuring side-holes that could be opened or closed, allowing for greater flexibility in playing modes. Other instruments in common use in

9801-480: The harp eventually became a national symbol. Lyres propagated through the same areas, as far east as Estonia . European music between 800 and 1100 became more sophisticated, more frequently requiring instruments capable of polyphony . The 9th-century Persian geographer Ibn Khordadbeh mentioned in his lexicographical discussion of music instruments that, in the Byzantine Empire , typical instruments included

9922-513: The highest trophic level at the highest risk for toxic effects. It has been known for over a century, that chromium electroplating is relatively easy from (di)chromate solutions, but difficult from Cr solutions. Several theories have been proposed to explain this finding. An earlier view suggested, that an active Cr species (perhaps, with a ligand rather than water) forms initially from electroreduced Cr . This active Cr species can be reduced into metallic chromium relatively easy. However,

10043-630: The human motor impulse to add sound to emotional movements such as dancing. Eventually, some cultures assigned ritual functions to their musical instruments, using them for hunting and various ceremonies. Those cultures developed more complex percussion instruments and other instruments such as ribbon reeds, flutes, and trumpets. Some of these labels carry far different connotations from those used in modern day; early flutes and trumpets are so-labeled for their basic operation and function rather than resemblance to modern instruments. Among early cultures for whom drums developed ritual, even sacred importance are

10164-574: The latter half of the sixteenth century, orchestration came into common practice as a method of writing music for a variety of instruments. Composers now specified orchestration where individual performers once applied their own discretion. The polyphonic style dominated popular music, and the instrument makers responded accordingly. Beginning in about 1400, the rate of development of musical instruments increased in earnest as compositions demanded more dynamic sounds. People also began writing books about creating, playing, and cataloging musical instruments;

10285-443: The latter of which has been excavated and preserved by archaeologists. The Zhou dynasty saw percussion instruments such as clappers , troughs, wooden fish , and yǔ (wooden tiger). Wind instruments such as flute, pan-pipes , pitch-pipes , and mouth organs also appeared in this time period. The xiao (an end-blown flute ) and various other instruments that spread through many cultures, came into use in China during and after

10406-582: The limitations of the process, which are overcome by plating extra thickness then grinding down and lapping to meet requirements, or to improve the overall aesthetics of the chromed piece. Increasing plating thickness amplifies surface defects and roughness in proportional severity, because hard chrome does not have a leveling effect. Pieces that are not ideally shaped in reference to electric field geometries (nearly every piece sent in for plating, except spheres and egg shaped objects) require even thicker plating to compensate for non-uniform deposition, and much of it

10527-433: The main ingredient. Hexavalent chromium plating solution is used for both decorative and hard plating, as well as bright dipping of copper alloys, chromic acid anodizing , and chromate conversion coating . A typical hexavalent chromium plating process is: The activation bath is typically a tank of chromic acid with a reverse current run through it. This etches the work-piece surface and removes any scale . In some cases,

10648-425: The main ingredient. Trivalent chromium plating is an alternative to hexavalent chromium in certain applications and thicknesses (e.g. decorative plating). A trivalent chromium plating process is similar to the hexavalent chromium plating process, except for the bath chemistry and anode composition. There are three main types of trivalent chromium bath configurations: The trivalent chromium-plating process can plate

10769-530: The microcracking associated with decorative chrome, making it ideal for industrial applications where durability and friction reduction are necessary. Thin dense chrome is commonly used in precision tools, aerospace, medical, and food processing equipment. Hard chrome , also known as industrial chrome or engineered chrome , is used to reduce friction, improve durability through abrasion tolerance and wear resistance in general, minimize galling or seizing of parts, expand chemical inertness to include

10890-483: The modern horn or, more colloquially, French horn, had emerged by 1725. The slide trumpet appeared, a variation that includes a long-throated mouthpiece that slid in and out, allowing the player infinite adjustments in pitch . This variation on the trumpet was unpopular due to the difficulty involved in playing it. Organs underwent tonal changes in the Baroque period, as manufacturers such as Abraham Jordan of London made

11011-458: The most profound changes occurred during the Renaissance period. Instruments took on other purposes than accompanying singing or dance, and performers used them as solo instruments. Keyboards and lutes developed as polyphonic instruments, and composers arranged increasingly complex pieces using more advanced tablature . Composers also began designing pieces of music for specific instruments. In

11132-400: The music that accompanied wedding and circumcision ceremonies. Persian miniatures provide information on the development of kettle drums in Mesopotamia that spread as far as Java. Various lutes, zithers, dulcimers , and harps spread as far as Madagascar to the south and modern-day Sulawesi to the east. Despite the influences of Greece and Rome, most musical instruments in Europe during

11253-516: The neck to large pipe organs. Literary accounts of organs being played in English Benedictine abbeys toward the end of the tenth century are the first references to organs being connected to churches. Reed players of the Middle Ages were limited to oboes ; no evidence of clarinets exists during this period. Musical instrument development was dominated by the Occident from 1400 on, indeed,

11374-504: The nevel must be similar to vertical harp due to its relation to nabla , the Phoenician term for "harp". In Greece , Rome , and Etruria , the use and development of musical instruments stood in stark contrast to those cultures' achievements in architecture and sculpture. The instruments of the time were simple and virtually all of them were imported from other cultures. Lyres were the principal instrument, as musicians used them to honor

11495-419: The old Slingerland Radio King snare drum is evidenced by myriad professional drummers who still used the snare in 2017, despite endorsing other brands. A departure from the standard Slingerland product line occurred during World War II when wood was used to manufacture drum parts that had traditionally been made of brass , chrome , nickel , and steel . This was due to the high demand for metals needed for

11616-538: The oldest known musical instrument and the only Neanderthal musical instrument. Mammoth bone and swan bone flutes have been found dating back to 30,000 to 37,000 years old in the Swabian Alps of Germany. The flutes were made in the Upper Paleolithic age, and are more commonly accepted as being the oldest known musical instruments. Archaeological evidence of musical instruments was discovered in excavations at

11737-428: The part may be over-plated and ground to size, or auxiliary anodes may be used around the hard-to-plate areas. Hexavalent chromium is also considerably more toxic than trivalent chromium, rendering it a major health risk both in manufacturing and disposal if not handled with care. Trivalent chromium plating , also known as tri-chrome , Cr , and chrome(III) plating, uses chromium sulfate or chromium chloride as

11858-533: The people of the New Kingdom began using oboes , trumpets, lyres , lutes , castanets , and cymbals . Unlike Mesopotamia and Egypt, professional musicians did not exist in Israel between 2000 and 1000 BC. While the history of musical instruments in Mesopotamia and Egypt relies on artistic representations, the culture in Israel produced few such representations. Scholars must therefore rely on information gleaned from

11979-766: The period of time loosely referred to as the post-classical era and Europe in particular as the Middle Ages , China developed a tradition of integrating musical influence from other regions. The first record of this type of influence is in 384 AD, when China established an orchestra in its imperial court after a conquest in Turkestan . Influences from Middle East, Persia, India, Mongolia, and other countries followed. In fact, Chinese tradition attributes many musical instruments from this period to those regions and countries. Cymbals gained popularity, along with more advanced trumpets, clarinets, pianos, oboes, flutes, drums, and lutes. Some of

12100-426: The process of assigning names to these instruments is challenging since there is no clear distinction among various instruments and the words used to describe them. Although Sumerian and Babylonian artists mainly depicted ceremonial instruments, historians have distinguished six idiophones used in early Mesopotamia: concussion clubs, clappers, sistra , bells, cymbals, and rattles. Sistra are depicted prominently in

12221-507: The region included vertical harps derived from those of the Orient , lutes of Egyptian design, various pipes and organs, and clappers, which were played primarily by women. Evidence of musical instruments in use by early civilizations of India is almost completely lacking, making it impossible to reliably attribute instruments to the Munda and Dravidian language-speaking cultures that first settled

12342-468: The rising popularity of the guitar. As the prevalence of string orchestras rose, wind instruments such as the flute, oboe, and bassoon were readmitted to counteract the monotony of hearing only strings. In the mid-seventeenth century, what was known as a hunter's horn underwent a transformation into an "art instrument" consisting of a lengthened tube, a narrower bore, a wider bell, and a much wider range. The details of this transformation are unclear, but

12463-405: The scores. Trumpets traditionally had a "defective" range—they were incapable of producing certain notes with precision. New instruments such as the clarinet , saxophone , and tuba became fixtures in orchestras. Instruments such as the clarinet also grew into entire "families" of instruments capable of different ranges: small clarinets, normal clarinets, bass clarinets, and so on. Accompanying

12584-399: The singing human voice. As a result, many instruments that were incapable of larger ranges and dynamics, and therefore were seen as unemotional, fell out of favor. One such instrument was the shawm. Bowed instruments such as the violin , viola , baryton , and various lutes dominated popular music. Beginning in around 1750, however, the lute disappeared from musical compositions in favor of

12705-421: The sixteenth century, musical instrument builders gave most instruments – such as the violin – the "classical shapes" they retain today. An emphasis on aesthetic beauty also developed; listeners were as pleased with the physical appearance of an instrument as they were with its sound. Therefore, builders paid special attention to materials and workmanship, and instruments became collectibles in homes and museums. It

12826-692: The slides and tremolos of Hindu music. Rhythm was of paramount importance in Indian music of the time, as evidenced by the frequent depiction of drums in reliefs dating to the post-classical era. The emphasis on rhythm is an aspect native to Indian music. Historians divide the development of musical instruments in medieval India between pre-Islamic and Islamic periods due to the different influence each period provided. In pre-Islamic times, idiophones such as handbells , cymbals, and peculiar instruments resembling gongs came into wide use in Hindu music. The gong-like instrument

12947-465: The specimens found cannot be irrefutably placed as the earliest musical instruments. The Divje Babe Flute is a perforated bone discovered in 1995, in the northwest region of Slovenia by archaeologist Ivan Turk. Its origin is disputed, with many arguing that it is most likely the product of carnivores chewing the bone, but Turk and others argue that it is a Neanderthal -made flute. With its age estimated between 43,400 and 67,000 years old, it would be

13068-501: The stops more expressive and added devices such as expressive pedals. Sachs viewed this trend as a "degeneration" of the general organ sound. During the Classical and Romantic periods of music, lasting from roughly 1750 to 1900, many musical instruments capable of producing new timbres and higher volume were developed and introduced into popular music. The design changes that broadened the quality of timbres allowed instruments to produce

13189-461: The way that modern large-scale manufacturing companies' are. Exceptions to nearly every strict product taxonomy existed. This is due in large part to the fact that parts would often be left over from year to year and would be used by workers even though some of those parts had been officially discontinued from the line. Jean-Paul Gaster of the American rock band Clutch uses Slingerland drums, and

13310-694: The wear resistance and service life of highly stressed arms parts. Hexavalent chromium is the most toxic form of chromium. In the U.S., the Environmental Protection Agency regulates it heavily. The EPA lists hexavalent chromium as a hazardous air pollutant because it is a human carcinogen , a "priority pollutant" under the Clean Water Act , and a "hazardous constituent" under the Resource Conservation and Recovery Act . Due to its low cathodic efficiency and high solution viscosity ,

13431-412: The workpieces at a similar temperature, rate and hardness, as compared to hexavalent chromium. Plating thickness ranges from 5 to 50 μin (0.13 to 1.27 μm). The functional advantages of trivalent chromium are higher cathode efficiency and better throwing power. Better throwing power means better production rates. Less energy is required because of the lower current densities required. The process

13552-502: The world. However, contact among civilizations caused rapid spread and adaptation of most instruments in places far from their origin. By the post-classical era , instruments from Mesopotamia were in maritime Southeast Asia , and Europeans played instruments originating from North Africa . Development in the Americas occurred at a slower pace, but cultures of North , Central , and South America shared musical instruments. By 1400, musical instrument development slowed in many areas and

13673-546: Was a bronze disk that was struck with a hammer instead of a mallet. Tubular drums, stick zithers ( veena ), short fiddles, double and triple flutes, coiled trumpets, and curved India horns emerged in this time period. Islamic influences brought new types of drum, perfectly circular or octagonal as opposed to the irregular pre-Islamic drums. Persian influence brought oboes and sitars , although Persian sitars had three strings and Indian version had from four to seven. The Islamic culture also introduced double- clarinet instruments as

13794-494: Was acquired from Gretsch (part of the Gibson Guitar Corporation by then) in 1994. Gibson revived the brand, but had limited success, due to premium pricing and poor economic conditions. In 1998, Slingerland released a model based on its Gene Krupa signature drum kit. In 2018, much if not all of the remaining warehouse stock of Slingerland drums, including bare shells, hardware and complete drum sets, were sold as

13915-409: Was dominated by the Occident . During the Classical and Romantic periods of music, lasting from roughly 1750 to 1900, many new musical instruments were developed. While the evolution of traditional musical instruments slowed beginning in the 20th century, the proliferation of electricity led to the invention of new electric and electronic instruments, such as electric guitars , synthesizers , and

14036-455: Was during this period that makers began constructing instruments of the same type in various sizes to meet the demand of consorts , or ensembles playing works written for these groups of instruments. Instrument builders developed other features that endure today. For example, while organs with multiple keyboards and pedals already existed, the first organs with solo stops emerged in the early fifteenth century. These stops were meant to produce

14157-755: Was first used in 1977 by the Santa Clara Vanguard under drum captain Fred Sanford and the Oakland Crusaders under Tom Float. Famous drum corps such as the 27th Lancers Drum and Bugle Corps of Revere, Massachusetts under Charlie Poole, the Bridgemen of Bayonne, New Jersey under Dennis Delucia, the Chicago Cavaliers under Gus Barbaro and Brian Callahan, the Pittsburgh Royal Crusaders and

14278-503: Was later moved from Chicago proper to Niles , a suburb in Cook County, Illinois . Although the Slingerland company was best known as a drum kit manufacturer, it also made guitars in the 1930s. The Songster electric guitar , featured in a 1939 company catalog, pre-dates Les Paul's "log" guitar and is probably the earliest Spanish-style solid-body electric guitar model. The guitar's pickup includes individual string magnets as well as

14399-513: Was previously common only in singing. Similar to the process of reduplication in language, instrument players first developed repetition and then arrangement. An early form of melody was produced by pounding two stamping tubes of slightly different sizes—one tube would produce a "clear" sound and the other would answer with a "darker" sound. Such instrument pairs also included bullroarers , slit drums, shell trumpets , and skin drums. Cultures who used these instrument pairs associated them with gender;

14520-473: Was started in 1926 in answer to the entry of the Ludwig & Ludwig drum company into the banjo market . A resourceful and energetic businessman, H.H. established an extensive dealer network throughout the U.S., the then-territory of Hawaii (in the early 1930s) and China. After H.H.'s death from a stroke, the company was run by his wife, Nona, and one of their children, Henry Jr. The company's manufacturing plant

14641-571: Was the gong. While the gong likely originated in the geographical area between Tibet and Burma , it was part of every category of human activity in maritime Southeast Asia including Java . The areas of Mesopotamia and the Arabian Peninsula experiences rapid growth and sharing of musical instruments once they were united by Islamic culture in the seventh century. Frame drums and cylindrical drums of various depths were immensely important in all genres of music. Conical oboes were involved in
