Riff in the context of "Industrial metal"

Rhythm (from Greek ῥυθμός, rhythmos, "any regular recurring motion, symmetry") generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years.

The Oxford English Dictionary defines rhythm as "The measured flow of words or phrases in verse, forming various patterns of sound as determined by the relation of long and short or stressed and unstressed syllables in a metrical foot or line; an instance of this".

A hook is a musical idea, often a short riff, passage, or phrase, that is used in popular music to make a song appealing and to "catch the ear of the listener." The term generally applies to popular music, especially rock, R&B, hip hop, dance, and pop. In these genres, the hook is often found in, or consists of, the chorus. A hook can be either melodic or rhythmic, and often incorporates the main motif for a piece of music.

Lester Willis Young (August 27, 1909 – March 15, 1959), nicknamed "Pres" or "Prez", was an American jazz tenor saxophonist and occasional clarinetist.

Coming to prominence while a member of Count Basie's orchestra, Young was one of the most influential players on his instrument. In contrast to many of his hard-driving peers, Young played with a relaxed, cool tone and used sophisticated harmonies, using what one critic called "a free-floating style, wheeling and diving like a gull, banking with low, funky riffs that pleased dancers and listeners alike".

Rap metal is a fusion genre that combines hip hop with heavy metal. It usually consists of heavy metal guitar riffs, funk metal elements, rapped vocals and sometimes turntables.

"Shave and a Haircut" and the associated response "two bits" is a seven-note musical call-and-response couplet, riff or fanfare popularly used at the end of a musical performance, usually for comedic effect. It is used melodically or rhythmically, for example as a door knocker.

"Two bits" is a term in the United States and Canada for 25 cents, equivalent to a U.S. quarter. "Four bits" and "six bits" are also occasionally used, for example in the cheer "Two bits, four bits, six bits, a dollar." The final words may also be "get lost", "drop dead" (in Australia), or some other facetious expression. In the UK, it was often said as "five bob" (slang for five shillings), although words are now rarely used to accompany the rhythm or the tune.

William James "Count" Basie (/ˈbeɪsi/; August 21, 1904 – April 26, 1984) was an American jazz pianist, organist, bandleader, and composer. In 1935, he formed the Count Basie Orchestra, and in 1936 took them to Chicago for a long engagement and their first recording. He led the group for almost 50 years, creating innovations like the use of two "split" tenor saxophones, emphasizing the rhythm section, riffing with a big band, using arrangers to broaden their sound, his minimalist piano style, and others.

Many musicians came to prominence under his direction, including the tenor saxophonists Lester Young and Herschel Evans, the guitarist Freddie Green, trumpeters Buck Clayton and Harry "Sweets" Edison, plunger trombonist Al Grey, and singers Jimmy Rushing, Helen Humes, Dennis Rowland, Thelma Carpenter, and Joe Williams.

Benjamin Moten (November 13, 1893 – April 2, 1935) was an American jazz pianist and band leader born and raised in Kansas City, Missouri, United States.

He led his Kansas City Orchestra, the most important of the regional, blues-based orchestras active in the Midwest in the 1920s, and helped to develop the riffing style that would come to define many of the 1930s big bands. The jazz standard "Moten Swing" bears his name.

Lead guitar (also known as solo guitar) is a musical part for a guitar in which the guitarist plays melody lines, instrumental fill passages, guitar solos, and occasionally, some riffs and chords within a song structure. The lead is the featured guitar, which usually plays single-note-based lines or double-stops.In rock, heavy metal, blues, jazz, punk, fusion, some pop, and other music styles, lead guitar lines are often supported by a second guitarist who plays rhythm guitar, which consists of accompaniment chords and riffs.

Glam metal (also known as hair metal or pop metal) is a subgenre of heavy metal that features pop-influenced hooks and guitar riffs, upbeat rock anthems, and slow power ballads. It borrows heavily from the fashion and image of 1970s glam rock.

Early glam metal evolved directly from the glam rock movement of the 1970s, as visual elements taken from acts such as T. Rex, David Bowie and New York Dolls (and to a lesser extent, the punk and new wave movements taking place concurrently in New York City) were fused with the decidedly more heavy metal leaning and theatrical acts such as Alice Cooper and Kiss. The first examples of this fusion began appearing in the late 1970s and early 1980s in the United States, particularly on the Los Angeles Sunset Strip music scene. Early glam metal bands include Mötley Crüe, Hanoi Rocks, Ratt, Quiet Riot, Twisted Sister, Bon Jovi, and Dokken. Glam metal achieved significant commercial success from approximately 1982 to 1991, bringing to prominence bands such as Poison, Skid Row, Cinderella, and Warrant. From a strictly visual perspective, glam metal is defined by flashy and tight-fitting clothing, makeup, and an overall androgynous aesthetic in which the traditional "denim & leather" aspect of heavy metal culture is replaced by spandex, lace, and usually heavy use of bright colours.

The swing era (also frequently referred to as the big band era) was the period (1933–1947) when big band swing music was the most popular music in the United States, especially for teenagers. Though this was its most popular period, the music had actually been around since the late 1920s and early 1930s, being played by black bands led by such artists as Duke Ellington, Jimmie Lunceford, Bennie Moten, Cab Calloway, Earl Hines, and Fletcher Henderson, and white bands from the 1920s led by the likes of Jean Goldkette, Russ Morgan and Isham Jones. An early milestone in the era was from "the King of Swing" Benny Goodman's performance at the Palomar Ballroom in Los Angeles on August 21, 1935, bringing the music to the rest of the country. The 1930s also became the era of other great soloists: the tenor saxophonists Coleman Hawkins, Ben Webster and Lester Young; the alto saxophonists Benny Carter and Johnny Hodges; the drummers Chick Webb, Gene Krupa, Jo Jones and Sid Catlett; the pianists Fats Waller and Teddy Wilson; the trumpeters Louis Armstrong, Roy Eldridge, Bunny Berigan, and Rex Stewart.

Developments in dance orchestras and jazz music culminated in swing music during the early 1930s. It brought to fruition ideas originated with Louis Armstrong, Earl Hines, Fletcher Henderson, Duke Ellington, and Jean Goldkette. The swing era also was precipitated by spicing up familiar commercial, popular material with a Harlem-oriented flavor and selling it via a white band for a white musical/commercial audience. In Benny Goodman's band, the most diversified styles flowed together: the ensemble style developed by Fletcher Henderson, who arranged for Goodman; the riff technique of Kansas City; and the precision and training of many white musicians. On the other hand, the easy melodic quality and clean intonation of Goodman's band made it possible to "sell" jazz to a mass audience.

Charles Edward Anderson "Chuck" Berry (October 18, 1926 – March 18, 2017) was an American guitarist, singer, and songwriter; and one of the pioneers of rock and roll. Nicknamed the "Father of Rock and Roll", he refined and developed rhythm and blues into the major elements that made rock and roll distinctive with songs such as "Maybellene" (1955), "Roll Over Beethoven" (1956), "Rock and Roll Music" (1957), and "Johnny B. Goode" (1958). Writing lyrics that focused on teen life and consumerism, and developing a music style that included guitar solos and showmanship, Berry was a major influence on subsequent rock music.

Born into a middle-class black family in St. Louis, Berry had an interest in music from an early age and gave his first public performance at Sumner High School. While still a high school student, he was convicted of armed robbery and was sent to a reformatory, where he was held from 1944 to 1947. After his release, Berry settled into married life and worked at an automobile assembly plant. By early 1953, influenced by the guitar riffs and showmanship techniques of the blues musician T-Bone Walker, Berry began performing with the Johnnie Johnson Trio. His break came when he traveled to Chicago in May 1955 and met Muddy Waters, who suggested he contact Leonard Chess, of Chess Records. With Chess, he recorded "Maybellene"—Berry's adaptation of the country song "Ida Red"—which sold over a million copies, reaching number one on Billboard magazine's rhythm and blues chart.
