A five-note chord formed by adding the 7th a 3rd above a triad, and then the 9th another 3rd above. This 9th resolves downward by a 2nd. A ninth chord on the dominant is called a “dominant ninth,” used in four-part writing with 1 note omitted.
三和音に３度上の第７音、その上さらに３度上の第９音を重ね、五和音としたもの。 この第９音は２度下行して解決する。 属音上の九の和音を「属九の和音」といい、四声体では１音を省略して使う。
