..Swing

Swing music, also known as swing jazz, is a form of jazz music that developed during the 1920s and had solidified as a distinctive style by 1935 in the United States. Swing is distinguished primarily by a strong rhythm section, usually including double bass and drums, medium to fast tempo, and the distinctive swing time rhythm that is common to many forms of jazz.

History

Swing, like several other styles of 20th Century popular music, has its origins in African rhythms. Traditional West African music brought to the United States and elsewhere by enslaved Africans hybridized with western music to eventually create a distinct style. The first recordings labeled swing style date from the 1920s, and come from both the United States and the United Kingdom. They are characterized by the swing rhythm already at that time common in jazz music, and a distinctive lively style which is harder to define. Although swing evolved out of the lively jazz experimentation that began in New Orleans and that developed further (and in varying forms) in Kansas City and New York City, what is now called swing diverged from other jazz music in ways that distinguished it as a form in its own right.
Although swing was performed by small ensembles as well, the quintessential swing bands tended to be bigger and more crowded than other jazz bands, necessitating a slightly more detailed and organized type of composition and notation than was then the norm. Band leaders put more energy into developing arrangements, perhaps reducing the chaos that might result from as many as 12 or 16 musicians spontaneously improvising. But the best swing bands at the height of the era explored the full gamut of possibilities from spontaneous ensemble playing to highly orchestrated music in the vein of European art music.
A typical song played in swing style would feature a strong, anchoring rhythm section in support of more loosely tied wind, brass, and later, string and/or vocal sections. The level of improvisation that the audience might expect at any one time varied depending on the arrangement, the band, the song, and the band-leader. The most common style consisted of having a soloist take center stage, and improvise a solo within the framework of her or his bandmates playing support. As a song progressed, multiple soloists might be expected to take over and individually improvise their own part; however, it wasn’t unusual to have two or three band members improvising at any one time.
Swing jazz began to be embraced by the public around 1935. Prior to that, it had had limited acceptance, mostly among African American audiences. As the music began to grow in popularity throughout the States--as with many new popular musical styles--it met with some resistance from the conservative public, for its fast tempos, occasionally risqué lyrics, and other cultural associations such as the sometimes frenetic swing dancing that accompanied performances. Harsher conflicts arose when Swing spread to other countries; for example, in Germany it was forbidden by the Nazi regime on the basis of its connection to African and Jewish musicians (see Swing Kids). And, while jazz music was initially embraced during the early years of the Soviet Union, it was soon forbidden as a result of being deemed politically unacceptable.
In the U.S., By the late 1930s and early 1940s, swing had become the most popular musical style and remained so for several years, until it was supplanted in the late ‘40s by the pop standards sung by the crooners who grew out of the Big Band tradition that swing began. Bandleaders such as the Dorsey Brothers often helped launch the careers of vocalists who went on to popularity as solo artists, such as Frank Sinatra.
Swing music began to decline in popularity during WWII because of several factors. Most importantly it became difficult to staff a "big band" because many musicians were overseas fighting in the war. Also, the cost of touring with a large ensemble became prohibitive because of wartime economics. These two factors made smaller 3 to 5 piece combos more profitable and manageable. A third reason is the recording bans of 1942 and 1948 because of musicians' union strikes. In 1948, there were no records legally made at all, although independent labels continued to bootleg records in small numbers. When the ban was over in January 1949, swing had evolved into new styles such as jump blues and bebop.

Swing revival

The Swing Revival was a 1990s and early 2000s-era period of renewed popular interest in swing and jump blues music from the 1930s and 1940s as exemplified by Louis Prima. Influential swing revival groups included Big Bad Voodoo Daddy, the Cherry Poppin' Daddies, and The Brian Setzer Orchestra.
Most swing revival bands were based around a rock and roll rhythm section of electric guitar, double bass, and drum kit, with a three or four instrument horn section, which usually consisted of trumpet, saxophone, and trombone. One of the revival bands, The Brian Setzer Orchestra, used a much larger horn section, with thirteen wind instruments, which more closely matched the size of the groups during the swing era in the 1930s.
Much of the swing revival drew on the style popularized by Louis Prima, and groups such as the Brian Setzer Orchestra recorded several of Prima's pieces. Swing revival bands focused on the highly rehearsed and arranged sweet style rather than the hot style, which was more improvisational, and which focused on instrumentalist virtuosity.
