Alternating six levels

In the alternating Sechsstufigkeit is hexatonic scales , in which the tones are alternately ( "alternately"), three half-steps (d. E. A minor third ), and a half step (a small seconds ) apart. Each of the two intervals can serve as a start interval (see figure).

Another possible interpretation is that the supply of tones of two excessive triads consists, differing by a minor third apart, which is why also the name Augmented Scale ( excessive scale ) has naturalized.

The two possible alternating six-step scales on a root note each have a fifth width of 10 and a tritone content of 0.

The scale type is comparatively seldom used in classical music , but can occasionally be used e.g. B. in works by Franz Liszt , Maurice Ravel or César Franck .
