  • Big Band

    The big band is a type of musical ensemble associated with jazz, a style of music which became popular during the Swing Era from the early 1930s until the late 1950s. Big bands evolved with the times and continues to today. A big band typically consists of approximately 12 to 25 musicians and contains saxophones, trumpets, trombones, marimba, singers (or vocalists), and a rhythm section. The terms jazz band, jazz ensemble, stage band, jazz orchestra, society band and dance band may be used to describe a specific type of big band. In contrast to smaller jazz combos, in which most of the music is improvised, or created spontaneously, music played by big bands is highly "arranged", or prepared in advance and notated on sheet music. The music is traditionally called "charts". Improvised solos may be played only when called for by the arranger.

    Towards the end of the 1920s, a new form of Big Band emerged which was more authentically "jazz," in that more space was given to improvised soloing. This form of music never gained the popularity of the dance form of jazz. The few recordings made in this form of jazz were labelled race records and were intended for a limited urban audience. Few white musicians were familiar with this music, Johnny Mercer, Harold Arlen and Hoagy Carmichael being notable exceptions. The three major centres in this development were New York City, Chicago and Kansas City. In the former, a sophisticated approach to arranging predominated, first in the work of Don Redman for the Fletcher Henderson band, later in the work of Duke Ellington for his Cotton Club orchestra, and Walter 'Foots' Thomas for Cab Calloway's, Charlie Spivak and His Orchestra, and Mel Torm?'s Mel-Tones. Some big ensembles, like the Joe "King" Oliver outfit played a kind of half arranged, half improvised jazz, often relying on head arrangements. Other great bands, like the one of Luis Russell became a vehicle for star instrumentalists, in his case Louis Armstrong. There the whole arrangement had to promote all the possibilities of the star, although they often contained very good musicians, like Henry "Red" Allen, J. C. Higginbotham and Charlie Holmes. Others such as Alvino Rey grew popular with shows in New York City and then toured the country sharing their hit songs and new musical styles.

    Typical big band arrangements of the swing period are written in strophic form with the same phrase and chord structure repeated several times. Each iteration, or chorus, most commonly follows Twelve bar blues form or Thirty-two-bar (AABA) song form. The first chorus of an arrangement typically introduces the melody, and is followed by subsequent choruses of development. This development may take the form of improvised solos, written soli sections, and shout choruses. An arrangement's first chorus is sometimes preceded by an introduction, which may be as short as a few measures or may extend to chorus of its own. Many arrangements contain an interlude, often similar in content to the introduction, inserted between some or all choruses. Other methods of embellishing the form include modulations and cadential extensions.
