The shout tradition fit well into this framework and became ever more popular across the spectrum of Pentecostalism and, eventually, the larger charismatic Evangelical world.
This has had an outsize influence on the spread (and musical structure) of the tradition in modern times, in addition to the popularity of videos on social media depicting the practice.
[3] In its most standard form, shout music is characterized by very fast tempo, chromatic basslines and piano/organ chords, snare hits and hand claps on the upbeat of each beat.
Often bands will break into shout music at the end of a song or as a finale, or at a particularly high emotional point during a church service or sermon—often cued by the singer or speaker themselves.
Shouts typically lack sheet music and can vary from less than one minute to as long as over an hour and may span many different songs.
The United House of Prayer For All People (UHOP), an African-American denomination founded in 1919 in Massachusetts, is particularly known for its shout bands and distinctive form of shout music: brass players, predominantly trombone-based, inspired by jazz, blues and Dixieland, gospel and old-time spirituals: a more soulful/spiritual version of a New Orleans brass band.
This kind of shout music is made to closely emulate the exact sound and techniques used by the voices of singers and choirs, including but not limited to vibratos, slurs, and glissando.
Though they are not usually seen, other instruments are also utilized in such shout bands, including trumpets, flugelhorns, saxophones, clarinets, flutes, washboards and more.
