Oom-pah

Oom-pah, Oompah, Ooumpah or Umpapa is an onomatopoeic term describing the rhythmic sound of a deep brass instrument in combination with the response of other instruments or registers in a band, a form of background ostinato.

The pah is played on the off-beats by higher-pitched instruments such as the clarinet, accordion or trombone.

Oompah is often associated with Volkstümliche Musik, a form of popular German music, and with polka.

A more modern variation is the playing of contemporary pop and rock songs in an Oompah style, by bands such as Global Kryner (Austria), Oompah Brass (UK) (who dubbed the style "Oompop"),[3] and Brumpah (UK, West Midlands).

[4] The American jam band Phish features the oom-pah-pah in their song "Harpua".
