Viennese trichord

In music theory, a Viennese trichord (also Viennese fourth chord and tritone-fourth chord), named for the Second Viennese School, is prime form <0,1,6>. It has Forte # 3-5. As opposed to Hindemith and 037 ( Play ), "Composers such as Webern ... are partial to 016 trichords, given their 'more dissonant' inclusion of ics 1 and 6."

In jazz and popular music, the chord usually has a dominant function, being the third, seventh, and added sixth/thirteenth of a dominant chord with elided root (and fifth, see jazz chord).
