Anharmoniuden

Anharmoniuden, also known as the anharmonic tone, is a musical interval that is not part of the standard diatonic scale. It is formed by raising the third degree of the major scale by a semitone, resulting in a minor third interval. This interval is often used in jazz and other forms of modern music to create a sense of tension and dissonance.

The anharmonic tone is named after the German composer and theorist Johann Philipp Kirnberger, who first described it in his 1779 work "Die Kunst des reinen Satzes." Kirnberger used the term "anharmonisch" to describe the interval because it is not found in the traditional harmonic system of the time.

It is also used in other forms of modern music, such as rock and pop, to create a sense of tension and dissonance.
