Swing is an outgrowth of the 1920s big band traditions in Chicago, Kansas City, and New York City. By the 1930s, these and other cities became major centers for the development of the swing style. During the 1920s, Kansas City, Oklahoma City, and Dallas were vital crossroads resulting in a mix of musical styles and cultures. Transcontinental trips often required a stop in one of these cities. Kansas City, in particular, became a wide-open town totally ingrained in the entertainment business. Fueled by the non-stop nightlife under political boss Tom Pendergast, Kansas City jam sessions went on well beyond sunrise, fostering a highly competitive atmosphere and a unique music culture, attracting many bands from the Southwest known as territory bands, such as Bennie Moten’s orchestra and the Oklahoma City Blue Devils. Count Basie became an Oklahoma City Blue Devil around 1929 and also played with Bennie Moten. After the end of both bands, Basie formed his own orchestra, recruiting members from these two bands.

In Kansas City, Bennie Moten’s and Count Basie’s bands had begun developing a looser type of big band arrangement that allowed for freer styles of soloing, giving rise to a unique Kansas City swing style in the 1930s. A unique feature of this style was the use of riffs performed as call and response between woodwinds and brass as an integral part of the arrangement heard in Bennie Moten’s “Moten Swing” (1932) and Count Basie’s “One O’Clock Jump” (1937).

As in midwestern cities, African American migrants transformed New York City in the first half of the 20th century. In Harlem, the creative and literary arts, Black musicals, and big band entertainment flourished within the movement known as the Harlem Renaissance, in which music played as great or possibly a greater role than literature. African American theaters and night clubs, the Apollo, the Savoy, and the Lafayette, became legendary for presenting jazz combos and orchestras. The Cotton Club started in Harlem before it moved downtown. Performers played, sang, danced, and presented shows and stand-up comedy in these large entertainment venues. Jazz orchestras were necessary for the shows and musicals, and well-trained musicians were highly valued.

Ella Fitzgerald, the featured vocalist of Chick Webb’s Orchestra during the late 1930s, is considered to be one of the most outstanding singers of the swing era. Her vocal command expanded to an unusual range of four octaves, and she is best known for her melodic approach to scatting. Fitzgerald was unique in her ability to render exact imitations of nearly any instrument in the band. Fitzgerald recorded several standards that became hit songs. Her version of the nursery rhyme “A-Tisket, A-Tasket” (1938) brought her international fame. Among all the jazz vocalists that followed, most cite her as having the most influence on their scatting style. Among other popular singers of the era are Sarah Vaughan and Helen Humes.

Other renowned vocalists are blues singers Jimmy Rushing with “You Can Depend on Me” and Joe Williams’s “Roll ’Em Pete,” featured with the Count Basie Orchestra, whose repertoire included ballads, jazz and pop standards.

Afro-Cuban Swing Orchestras

A distinctly new genre appeared in the late 1930s that to some degree bridged the differences between big band swing and bebop combos, and this was West Indian influenced music. Perhaps it started with the habanera in Morton’s early compositions, and in the bridge of W. C. Handy’s “St. Louis Blues,” but by the late 1930s, with the migration of Cubans and Puerto Ricans to New York City, Afro-Cuban music emerged along with new dances, such as the rhumba. Cubans Mario Bauzá and Machito (Francisco Raúl Gutiérrez Grillo), founder of the Afro-Cubans; Puerto Rican Ernesto Antonio “Tito” Puente with “Oye como va”; and Afro-Cuban drummer Chano Pozo (Luciano Pozo González), famous for playing with and influencing Dizzy Gillespie’s “Manteca,” were among the most prominent band leaders and musicians. These artists added new instruments—such as congas, other percussion instruments, timbales, maracas, and claves—and relied on powerful multi-rhythmic pulses to highlight jazz compositions within the big band as well as the small combo formats. Charlie Parker’s album South of the Border illustrated the influence of this genre on a bop artist, and the Tokyo Cuban Boys, an Afro-Cuban band dating from the post–World War II years, exemplified the music’s international appeal.

The most prominent features of big band swing were the use of written arrangements and improvised solos, repetitive horn riffs, call and response between the brass and reed sections, and a rhythmic drive derived from walking and/or boogie-woogie type bass lines.

In swing, the saxophone was usually featured as the leading instrumental soloist. Bassists generally assumed the role of timekeeper, while drummers functioned in a dual capacity. Foremost, they accentuated the movement of choreographed dancers. This pattern reinforced the second and fourth beat of every measure and later became known as a “back beat.” Additionally, the drummer accommodated the improvisations of soloists, providing a non-intrusive, laid-back swing pattern.

Jazz vocalists during this era were highly influenced by horn players. They used their voices as instruments to demonstrate their command of scat singing.
