Q: Context: A chain gun is a type of machine gun or autocannon that uses an external source of power to cycle the weapon rather than diverting energy from the cartridge , and does so via a continuous loop of chain similar to that used on a motorcycle or bicycle . `` Chain gun '' is a registered trademark of Alliant Techsystems Inc. for a chain - powered weapon ., The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm. The term is from Middle French and originated as the diminutive of the word boulle (boullet) which means "small ball." Bullets are made of a variety of materials. They are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a large numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, and warfare. , An autocannon or automatic cannon is a large, fully automatic, rapid-fire projectile weapon that fires armour-piercing or explosive shells, as opposed to the bullet fired by a machine gun. Autocannons often have a larger calibre than a machine gun (e.g., 20 mm or greater), but are usually smaller than a field gun or other artillery. When used on its own, the word "autocannon" indicates a single-barrel weapon. When multiple rotating barrels are involved, the word "rotary" is added, and such a weapon is referred to as a "rotary autocannon." Modern autocannons are typically not single soldier-portable or stand-alone units, rather they are usually vehicle-mounted, aircraft-mounted, or boat-mounted, or even remote-operated as in some naval applications. As such, ammunition is typically fed from a belt to reduce reloading or for a faster rate of fire, but a magazine remains an option. They can use a variety of ammunition: common shells include high-explosive dual-purpose types (HEDP), any variety of armour-piercing (AP) types, such as composite rigid (APCR) or discarding sabot types (APDS)., A battle rifle is a military service rifle that fires a full-power rifle cartridge, such as 7.62×51mm NATO, 7.62×54mmR, 7.92x57mm Mauser, .303 British, or .30-06 Springfield. Compared to assault rifles and their intermediate cartridges, the higher-caliber rounds provide greater power and range, though they have greater weight and produce stronger recoil, making them less than ideal for fully automatic fire., A field gun is an artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march and when in combat could be moved about the battlefield in response to changing circumstances (field artillery), as opposed to guns installed in a fort (garrison artillery/coastal artillery), or to siege cannon or mortars which were too large to be moved quickly, and would be used only in a prolonged siege., A submachine gun (SMG) is an air-cooled, magazine-fed, automatic carbine designed to fire pistol cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun., Rate of fire is the frequency at which a specific weapon can fire or launch its projectiles. It is usually measured in rounds per minute (RPM or round/min), or rounds per second (RPS or round/s)., A machine gun is a fully automatic mounted or portable firearm, designed to fire bullets in quick succession from an ammunition belt or magazine, typically at a rate of 300 to 1800 rounds per minute. Fully automatic firearms are generally categorized as submachine guns, assault rifles, battle rifles, automatic shotguns, machine guns, or autocannons. Machine guns with multiple rotating barrels are referred to as "rotary machine guns"., An automatic shotgun is an automatic firearm that fires shotgun shells and uses some of the energy of each shot to automatically cycle the action and load a new round. It will fire repeatedly until the trigger is released or ammunition runs out. Automatic shotguns have a very limited range, but provide tremendous firepower at close range., A shotgun (also known as a scattergun, or historically as a fowling piece) is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug. Shotguns come in a wide variety of sizes, ranging from 5.5 mm (.22 inch) bore up to bore, and in a range of firearm operating mechanisms, including breech loading, single-barreled, double or combination gun, pump-action, bolt-, and lever-action, semi-automatic, and even fully automatic variants., Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantry's small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an army's total firepower., An assault rifle is a selective-fire rifle that uses an intermediate cartridge and a detachable magazine. Assault rifles were first used during World War II. Though Western nations were slow to accept the assault rifle concept after World War II, by the end of the 20th century they had become the standard weapon in most of the world's armies, replacing semi-automatic rifles, battle rifles and sub-machine guns in most roles. Examples include the StG 44, AK-47 and the M16 rifle., Subject: chain gun, Relation: subclass_of, Options: (A) ability (B) action (C) ammunition (D) army (E) artillery (F) assault rifle (G) autocannon (H) battle (I) battle rifle (J) belt (K) bullet (L) cannon (M) class (N) energy (O) field gun (P) fire (Q) firearm (R) fort (S) gun (T) hunting (U) infantry (V) lighter (W) machine (X) magazine (Y) march (Z) military ([) option (\) part (]) power (^) projectile (_) rate (`) rifle (a) service (b) shooting (c) shot (d) shotgun (e) single (f) solid (g) submachine gun (h) technology (i) term (j) variety (k) vehicle (l) weapon (m) word

Q: Context: A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores)., Doo-wop is a genre of music that was developed in African-Americans communities of New York City, Philadelphia, Chicago, Baltimore, Newark, Pittsburgh, Cincinnati, Detroit, Washington, D.C. and Los Angeles in the 1940s, achieving mainstream popularity in the 1950s and early 1960s. Built upon vocal harmony, doo-wop was one of the most mainstream, pop-oriented R&B styles of the time. Singer Bill Kenny (19141978) is often called the "Godfather of Doo-wop" for his introducing the "top and bottom" format which featured a high tenor singing the lead and a bass singer reciting the lyrics in the middle of the song. Doo-wop features vocal group harmony, nonsense syllables, a simple beat, sometimes little or no instrumentation, and simple music and lyrics., `` Stand by Me '' is a song originally performed by American singer - songwriter Ben E. King , written by King , Jerry Leiber and Mike Stoller . According to King , the song title is derived and was inspired by a spiritual composition by Sam Cooke called `` Stand by Me Father '' ( although Mike Stoller has stated differently ) . This spiritual was sung by The Soul Stirrers with Johnnie Taylor singing lead . There have been over 400 recorded versions of `` Stand by Me '' performed by many artists . The song has been featured on the soundtrack of the 1986 film Stand by Me . In 2012 it was estimated that the songs royalties had topped £ 17 million , making it the sixth highest earning song as of that time . 50 % of the royalties were paid to King . In 2015 , King 's original version was inducted into the National Recording Registry by the Library of Congress for being `` culturally , historically , or aesthetically significant '' , just under five weeks before King 's death . Later in the year the 2015 line up of The Drifters covered the song in tribute to King ., Johnnie Harrison Taylor (May 5, 1934  May 31, 2000) was an American vocalist in a wide variety of genres, from blues, rhythm and blues, soul, and gospel to pop, doo-wop and disco., The Drifters are a long-lasting American doo-wop and R&B/soul vocal group. They were originally formed to serve as a backing group for Clyde McPhatter (of Billy Ward and his Dominoes) in 1953., "Yakety Yak" is a song written, produced, and arranged by Jerry Leiber and Mike Stoller for The Coasters and released on Atlantic Records in 1958, spending seven weeks as #1 on the R&B charts and a week as number one on the Top 100 pop list. This song was one of a string of singles released by The Coasters between 1957 and 1959 that dominated the charts, one of the biggest performing acts of the rock and roll era., Lyricist Jerome "Jerry" Leiber (April 25, 1933  August 22, 2011) and composer Mike Stoller (born March 13, 1933) were American songwriting and record producing partners. They found initial successes as the writers of such crossover hit songs as "Hound Dog" (1952) and "Kansas City" (1952). Later in the 1950s, particularly through their work with The Coasters, they created a string of ground-breaking hitsincluding "Young Blood" (1957), "Searchin'" (1957), and "Yakety Yak" (1958)that used the humorous vernacular of teenagers sung in a style that was openly theatrical rather than personal. They were the first to surround black music with elaborate production values, enhancing its emotional power with The Drifters in "There Goes My Baby" (1958), which influenced Phil Spector, who studied their productions while playing guitar on their sessions., Rhythm and blues, often abbreviated as R&B or RnB, is a genre of popular African-American music that originated in the 1940s. The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when "urbane, rocking, jazz based music with a heavy, insistent beat" was becoming more popular.
In the commercial rhythm and blues music typical of the 1950s through the 1970s, the bands usually consisted of piano, one or two guitars, bass, drums, saxophone, and sometimes background vocalists. R&B lyrical themes often encapsulate the African-American experience of pain and the quest for freedom and joy. Lyrics focus heavily on the themes of triumphs and failures in terms of relationships, freedom, economics, aspirations, and sex., Phillip Harvey "Phil" Spector (born Harvey Phillip Spector; December 26, 1939) is an American record producer, musician, songwriter, and businessman who developed the Wall of Sound, a music production formula he described as a "Wagnerian" approach to rock and roll.

He is acknowledged as one of the most influential figures in pop music history., Disco is a genre of dance music containing elements of funk, soul, pop, and salsa. It achieved popularity during the mid-1970s to the early 1980s. Its initial audiences in the U.S. were club-goers from the gay, African American, Italian American, Latino, and psychedelic communities in Philadelphia and New York City during the late 1960s and early 1970s. Disco can be seen as a reaction against both the domination of rock music and the stigmatization of dance music by the counterculture during this period. It was popular with both men and women, from many different backgrounds., "Searchin'" is a song written by Jerry Leiber and Mike Stoller specifically for The Coasters. It was released as a single on Atco Records in March 1957, and topped the Rhythm and Blues Chart for twelve weeks.
