Doo-wop

Doo-wop (also spelled doowop and doo wop) is a subgenre of rhythm and blues music that originated in African-American communities during the 1940s, mainly in the large cities of the United States, including New York, Philadelphia, Pittsburgh, Chicago, Baltimore, Newark, Detroit, Washington, D.C., and Los Angeles. It features vocal group harmony that carries an engaging melodic line to a simple beat with little or no instrumentation. Lyrics are simple, usually about love, sung by a lead vocal over background vocals, and often featuring, in the bridge, a melodramatically heartfelt recitative addressed to the beloved. Harmonic singing of nonsense syllables (such as "doo-wop") is a common characteristic of these songs. Gaining popularity in the 1950s, doo-wop was commercially viable until the early 1960s and continued to influence performers in other genres.

Doo-wop has complex musical, social, and commercial origins.^{[citation needed]}

Doo-wop's style is a mixture of precedents in composition, orchestration, and vocals that figured in American popular music created by songwriters and vocal groups, both black and white, from the 1930s to the 1940s.

Composers such as Rodgers and Hart (in their 1934 song "Blue Moon"), and Hoagy Carmichael and Frank Loesser (in their 1938 "Heart and Soul") used a I–vi–ii–V-loop chord progression in those hit songs; composers of doo-wop songs varied this slightly but significantly to the chord progression I–vi–IV–V, so influential that it is sometimes referred to as the '50s progression. This characteristic harmonic layout was combined with the AABA chorus form typical for Tin Pan Alley songs.

Hit songs by black groups such as the Ink Spots ("If I Didn't Care", one of the best selling singles worldwide of all time, and "Address Unknown") and the Mills Brothers ("Paper Doll", "You Always Hurt the One You Love" and "Glow Worm") were generally slow songs in swing time with simple instrumentation. Doo-wop street singers generally performed without instrumentation, but made their musical style distinctive, whether using fast or slow tempos, by keeping time with a swing-like off-beat, while using the "doo-wop" syllables as a substitute for drums and a bass vocalist as a substitute for a bass instrument.

Doo-wop's characteristic vocal style was influenced by groups such as the Mills Brothers, whose close four-part harmony derived from the vocal harmonies of the earlier barbershop quartet.

The Four Knights' "Take Me Right Back to the Track" (1945), the Cats and the Fiddle's song "I Miss You So" (1939), and the Triangle Quartette's even earlier record "Doodlin' Back" (1929) prefigured doo-wop's rhythm and blues sound long before doo-wop became popular.
