Shout Music

The shout band tradition of the southeastern United States originated from the exuberant church music of North Carolina.African American brass players formed bands, predominantly trombone-based, inspired by jazz, blues and Dixieland, gospel and old-time spirituals: a more soulful version of a New Orleans Brass Band. The United House of Prayer For All People, an Apostolic denomination founded in 1919 in Massachusetts, is particularly known for its shout bands.

Shout Music is a type of gospel music characterized by very fast tempo, chromatic basslines, snare hits and hand claps on the upbeat of each beat. The organ typically plays dominant 7 chords while improvising over blues riffs. The pianist typically plays counter rhythms to the established rhythmic structure. There are many variations of this particular style of music. Often gospel artists will break into Shout Music at the end of a song or as a finale. Shout Music is used as a bed for vocal riffing and calling out of catch phrases, or "shouting."

While shout bands became prevalent during the 1920s and 1930s, by the 1960s the trombone, which allows for a wide range of emotive expression, emerged as the lead instrument within the shout band. Large groups of trombones are treated almost as a vocal choir, each with its own part.

Upbeat and engaging, shout band music consists of three sections: the recitive and call, which involves a musical statement from the trombones; the aria, which develops the melody and tempo; and the shout, the ending call-and-response. As the song progresses, the sound intensifies from a whisper at the beginning to an exuberant crescendo during the shout.
