Chamber jazz is a genre of jazz involving small, acoustic-based ensembles where group interplay is important. It is influenced aesthetically by musical neoclassicism and is often influenced by classical forms of Western music as well as non-Western music or culture. That stated, in many cases the influence is traditional Celtic music, Central European folk music, or Latin American music instead. The genre primarily began in Europe so significant neoclassical composers of Europe, like Igor Stravinsky, are important in it. The German ECM Records also played a role in it beginning in the late 1960s. It is also noted for using instruments not normally associated with jazz. For example, chamber jazz will make use of the oboe, mandolin, cymbalum, or the tabla.
