In Jazz, from around the 1960s, modern modes have been used. The first method is to use as an available note scale in certain code. The second method is to use mode as a tone, and to phrasing and harmony on it. In the second method, the emphasis is placed on the dominant tones and characteristic sounds.

In modern times, the mode is used to escape from music by a traditional narrow sense of tonality, that is, major and minor. For this reason, Ionian is not used because it makes it feel like a major tonality which is too much conventional tonality.
