As we know, the augmented is a symmetrically built scale. Symmetric is the word used to describe scales (and chords) where more than one root will result in the same set of notes. There are several different types e.g. Whole tone scale, Diminished scale, augmented scale, half diminished scale, two-semitone tritone scale.
The symmetric scales are rarely used for whole melodies or prolonged periods of improvising, because their regular intervals do not fit well with the Major scale or with any of the minor scales. However, they can be effective when improvising for adding brief passages of tension. They also play a useful role for improvising over a key change, since they can partially fit with two different Major or minor scales at the same time.
